Dendrobium huoshanense , a rare and endangered medicinal orchid species endemic to Huoshan County, Anhui Province, faces a severe limit of wild resources. Its medicinal efficacy derives from unique chemical constituents, which vary significantly across cultivation modes. We systematically compared sensory properties and nutritional constituents (polysaccharides, flavonoids, alkaloids, bibenzyls, minerals, and free amino acids) between D. huoshanense in three cultivation modes—greenhouse cultivation, understory gravel cultivation, and wild-simulated cultivation. Additionally, the gastroprotective effects of wild-simulated cultivated D. huoshanense on gastric mucosal epithelial cells were evaluated. Results demonstrated that wild-simulated cultivation yielded significantly higher levels of nutritional constituents compared to gravel and greenhouse cultivation. Furthermore, wild-simulated cultivated D. huoshanense exhibited notable protective effects against gastric mucosal epithelial cell damage. This study not only elucidates the influence of cultivation modes on the chemical profile of D. huoshanense but also provides scientific evidence supporting its gastric protective properties, offering a foundation for its sustainable utilization and quality-oriented cultivation.

In this paper, a synthesized material change from perovskite-layer-structured La 2 Ti 2 O 7 to perovskite type LaTiO 3 induced by Li 2 CO 3 addition was observed. The [TiO 6 ] octahedral site symmetry and particle uniformity showed an obvious variation with the change from La 2 Ti 2 O 7 to LaTiO 3 . A broadband far-red emission from 670 to 780 nm emerged when Mn 4+ , Li + ions were co-doped. Furthermore, (Mn 4+ , Li + ) co-doped LaTiO 3 phosphor can be effectively excited by near-UV and blue lights, which is suitable for combining with commercial InGaN LED chips. The LaTiO 3 :0.4%Mn 4+ , 150%Li + phosphor exhibited a high quantum efficiency of 71.1% and a good thermal stability with emission intensity retained 65% at 423 K. Finally, a LED device was fabricated with the LaTiO 3 :0.4%Mn 4+ , 150%Li + phosphor, which matches well with the absorption of photochrome of P FR and shows a good potential for use in agricultural cultivation fields.

Artificial light-emitting diode (LED) light source, regarded as a front-runner technology for the promoting of plant growth, has attracted much attention toward the burgeoning fertilizer-free indoor plant cultivation. It still remains a challenge that explore a far-red-emitting phosphor of high-thermal stability. Overall, we report a Mn 4+ ion-doped ordered double perovskite tungstates prepared by high-temperature solid-state reaction method in air. The crystal structure, morphology, and fluorescence properties were investigated and discussed in detail. The far-red emission of the optimized CaSrMgWO 6 :1%Mn 4+ , covering the wavelength region of 630–780 nm, matches the absorption ranges of the chlorophyll a and phytochrome (P fr ). The value of Dq/B is estimated to be 2.81. Most notable is the excellent thermal quenching resistance of the Mn 4+ emission, remaining 86.7% at 150 °C, thereby suitably fabricating a far-red LED device. The LED light-driven regulation of the physiological and biochemical changes enables a proof-of-concept garlic cultivation. The growth of weight, stem length, and root length of the garlic was significantly promoted with the extra supply of the far-red light. This work demonstrates that the as-obtained far-red-emitting phosphor holds a promising perspective for the phosphor-converted far-red LED light sources toward the flourishing fertilizer-free indoor plant cultivation.

The development of high-brightness far-red-emitting phosphors with emission wavelength within 650–750 nm is of great significance for indoor plant cultivation light-emitting diode (LED) lighting. Herein, we demonstrate a novel efficient far-red-emitting phosphors CaMg 2 La 2 W 2 O 12 :Mn 4+ (abbreviated as CMLW:Mn 4+ ) toward application in plant cultivation LEDs. Interestingly, the CMLW:Mn 4+ phosphors show a broad excitation band in the 250–600 nm spectral range with two peaks at 352 and 479 nm, indicating they could be efficiently excited by near-ultraviolet and blue light. Under 352 nm excitation, the CMLW:Mn 4+ phosphors exhibit an intense far-red emission band in the wavelength range of 650–800 nm peaking at 708 nm, corresponding to the 2 E g → 4 A 2g transition of Mn 4+ ions. Mn 4+ doping concentration-dependent luminescence properties are studied in detail, and the concentration quenching mechanism is also investigated. Particularly, the internal quantum efficiency of CMLW:Mn 4+ phosphors reaches as high as 44%, and their PL spectra match well with the absorption spectrum of phytochrome P FR (P FR stands for far-red-absorbing form of phytochrome). Furthermore, a prototype LED device is fabricated by coating the as-prepared CMLW:0.8%Mn 4+ phosphors on a 460 nm blue LED chip, which produces bright far-red emissions upon 20–300 mA driving currents. This work reveals that the newly discovered far-red-emitting CMLW:Mn 4+ phosphors hold great potential for application in indoor plant cultivation.

Development of efficient sunlight conversion materials is critical for advancing sustainable agricultural practices, but current solutions often face challenges such as poor stability, high cost, and reliance on rare-earth elements. This study presents a rare-earth-free xCsMnCl 3 (H 2 O) 2 /(1−x)Cs 3 SbCl 6 heterojunction ( x = 1−0.65) synthesized via an eco-friendly mechanochemical method. By strategically combining Cs 3 SbCl 6 as a UV-absorbing donor with CsMnCl 3 (H 2 O) 2 as an efficient red emitter. The optimized heterojunction achieves a remarkable 36-fold enhancement at 626 nm (Full width at half maxima (FWHM) = 88 nm), perfectly matching chlorophyll a's absorption spectrum. Comprehensive experimental and theoretical analyses, including UV–vis absorption, photoluminescence (PL) spectroscopy, and density functional theory (DFT) calculations, reveal a dual enhancement mechanism: i) efficient interfacial electron-hole transfer and ii) suppression of non-radiative recombination through defect passivation. The practical application is demonstrated through a sunlight conversion film fabricated by embedding the 0.75CsMnCl 3 (H 2 O) 2 /0.25Cs 3 SbCl 6 composite in Ecoflex-0030, which exhibits exceptional environmental stability (90% PL retention after 90 days) and mechanical durability (500% tensile strain). The plant growth experiments confirm the film's agricultural efficacy, with chives and green cabbage growth rates increasing by 1.5- and 1.3-fold, respectively, compared to natural light conditions. This work not only addresses the limitations of existing light-conversion materials but also establishes a rare-earth-free, eco-friendly platform for energy-efficient agriculture.

The excessive use of antibiotics and subsequent release into the aquatic environment causes deleterious effects on organisms. Using easily separable catalysts to remove antibiotics from aquatic environments is an effective strategy to release the burden of the aquatic ecosystem. Herein, as the natural porous cellulose fiber, Juncus effusus (JE) exhibits distinctive designability on the functional materials. The JE-based W-doped Bi 2 S 3 photocatalysts (W-Bi 2 S 3 -JE) were obtained by in-situ coating on the surface of JE fibers to improve the photodegradation performance of tetracycline (TC) antibiotic pollutants. Owing to the natural porous net-working structure of JE fiber, the aggregation of particles is reduced, promoting adsorption and photocatalysis. Under the condition of pH = 3.0 and mass of photocatalyst is 100 mg, the photodegradation efficiency is 98 % under irradiation for 180 min and the photodegradation efficiency could maintain 78 % after five cycles. Finally, the cultivation of crops was conducted to investigate the purification property of the solution after photocatalytic degradation. Compared with the solution before photodegradation, mung bean seeds can take root and germinate well irrigated by the solution after photodegradation and the growth is as strong as that of agricultural irrigation water. The W-Bi 2 S 3 -JE photocatalyst provides an attractive approach to restore the aquatic ecosystem polluted by antibiotics of TC, improving the application potential in environmental remediation.

Panax notoginsengis an important functional health product, and has been used worldwide because of a wide range of pharmacological activities, of which the taproot is the main edible or medicinal part. However, the technologies for origin discrimination still need to be further studied. In this study, an ICP-MS/MS method for the accurate determination of 49 elements was established, whereby the instrumental detection limits (LODs) were between 0.0003 and 7.716 mg/kg, whereas the quantification limits (LOQs) were between 0.0011 and 25.7202 mg/kg, recovery of the method was in the range of 85.82% to 104.98%, and the relative standard deviations (RSDs) were lower than 10%. Based on the content of multi-element inP. notoginseng(total of 89 mixed samples), the discriminant models of origins and cultivation models were accurately determined by the neural networks (prediction accuracy was 0.9259 and area under ROC curve was 0.9750) and the support vector machine algorithm (both 1.0000), respectively. The discriminant models established in this study could be used to support transparency and traceability of supply chains ofP. notoginsengand thus avoid the fraud of geographic identification.Keywords:Panax notoginseng;ICP-MS/MS;multi-element;origin discrimination;cultivation model discrimination

Li 2 MgTiO 4 :Cr 3+ , Mn 4+ phosphors were successfully synthesized by the high-temperature solid-state reaction method. Cr 3+ , Mn 4+ co-doped Li 2 MgTiO 4 phosphors have two emission peaks at 674 nm and 719 nm, corresponding to 2 E→ 4 A 2 transitions of Mn 4+ and 2 E→ 4 A 2 transitions of Cr 3+ , respectively. The two emission peaks are matched with the absorption of P R and P FR , and the intensity ratio of the two emission peaks is adjusted by changing the doping concentration of Mn 4+ , indicating that the phosphors have potential applications in plant cultivation. In addition, it can be observed that the emission peak corresponding to Mn 4+ can decrease sharply with the increase of excitation wavelength, while the emission peak corresponding to Cr 3+ can change little, which indicates that the phosphors can be used for wavelength detection. The security ink prepared by Li 2 MgTiO 4 :Cr 3+ , Mn 4+ phosphors shows that it can be applied in anti-counterfeiting labels. These results suggest that Li 2 MgTiO 4 :Cr 3+ , Mn 4+ have the great potentiality to be used for plant cultivation, wavelength detection and anti-counterfeiting.

Paeonia lactiflora Pall. is an economically significant plant widely used in medicine and ornamentation, with a long history of cultivation. The prevalent cultivars of medicinal P. lactiflora in China display distinct morphological traits. Nevertheless, a systematic elucidation of their quality attributes remains to be achieved. This study employed ultra-performance liquid chromatography-quadrupole-orbitrap mass spectrometry (UPLC-Q-Orbitrap-MS) and ultra-performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-QQQ-MS/MS), combined with statistical analysis to investigate the metabolites of P. lactiflora roots in 17 medicinal cultivars from five major production regions in China. Significant morphological differences were observed in petal morphology, flower color, carpel features, as well as stem and leaf characteristics. In total, 167 compounds were identified or putatively characterized, including 101 phenolics, 36 terpenoids, 14 organic acids, eight amino acids, and eight other compounds (glycosides, polyols, lipids, and carbohydrates). The DD-SIMCA model established based on one-class classification successfully distinguished monopetalous red-flowered medicinal P. lactiflora from other types and differentiated herbs from Dao-di regions from those of non-Dao-di regions. Monopetalous red-flowered cultivars, representing an abundant germplasm resource, exhibited relatively high levels of terpenoids and phenolic compounds. This study has addressed the issue of compositional differences among different cultivars, screened out high-quality medicinal cultivars of P. lactiflora , and provided a theoretical basis for germplasm breeding work. Meanwhile, these findings offer a scientific rationale for the traditional view that MR cultivars are superior in traditional medicinal applications.

Radix Astragali (RA), the root of Astragalus membranaceus var. mongholicus (Bunge) P.K. Hsiao, known as “Huangqi” in Chinese, has been used as a traditional herbal medicine or food in China for more than 2,000 years and is now consumed globally. Unfortunately, the increasing demand for RA has led to the overexploitation of its wild stock, as well as quality problems, including adulteration and contamination. Therefore, the sustainable cultivation of RA is urgently needed. In the present research, semi-structured interviews and key informant interviews were conducted, over a 2-year period, to collect data from stakeholders in the main production areas; moreover, a targeted chemical analysis-based quality assessment strategy was applied to understand the quality of RA. Accordingly, 10 different types of value chains (VCs) were identified in RA production; meanwhile, the contents of the main active ingredients (astragaloside and calycosin-7-O-β-D-glucoside) were analyzed by HPLC-ELSD-UV and the yield of medicinal material was demined and further analyzed using k-means clustering analysis. The results show that the tight relationship between quality of the RA and stakeholders’ revenues among the VCs, which reflects a more general trend in the production system. Over the past few decades, vertical coordination has emerged increasingly in VCs of RA, which leads to a more coherent traceability system and rigorous regulations in the supply chains. Daodi herbs can be considered to be a standard that is distinctive with good quality characteristics that emphasize the origins of the medicinal plants. We find that the suitability of geographical areas and vertical integration can improve the VCs of RA, which further contributes to its quality control, as well as its sustainable production.

The dried rhizome ofNotopterygium incisum(NI) from theUmbelliferaefamily, genuinely produced in Sichuan, China, is a classic traditional Chinese medicinal herb for treating wind-dampness arthralgia. Due to scarce natural resources, wild NI is gradually being replaced by cultivated types. However, knowledge is limited regarding the differences in chemical composition and pharmacological effects between wild and cultivated NI and between Sichuan-grown and other-region-grown NI. In this study, a plant metabolomics strategy, based on GC–MS and UHPLC-Orbitrap MS, was employed to compare metabolic profiles between wild and cultivated NI and between cultivated NI from Sichuan and cultivated NI from Gansu and Qinghai. In total, 195 metabolites were identified, and the biosynthetic pathways of coumarins and phenolic acids, which were the most abundant secondary metabolites in NI, were summarized. Additionally, seven key metabolic intermediates were uncovered, revealing the reasons for the differences in metabolic profiles between wild and cultivated NI. The anti-inflammatory effect of wild and cultivated NI was verified by inflammatory gene expression and neutrophil count using a zebrafish yolk sac inflammation model. Overall, this study presents information on the types and synthesis of pharmacodynamic substances in NI and provides a basis for its cultivation and applications.

Soilless culture is gradually becoming a new direction in the development of agricultural cultivation. However, the synthetic substrates currently used suffer from the problems of being nutrient-less and non-degradable, which will ultimately lead to the misuse of chemical fertilizers and serious environmental pollution. In this study, L-Tyrosine(L-Tyr) was used as a nitrogen nutrient modifier, and L-Tyr-PCL-PCDL-PUF/KHA (L-Tyrosine-Polycaprolactone-Polycarbonate-Polyurethane Foam/Kalium Humate, LTPPPK) soilless substrate was prepared by using biodegradable polycaprolactone and potassium humate, a natural plant-stimulating hormone, as raw materials. The experimental results demonstrated that the incorporation of L-Tyr significantly enhanced the LTPPPK material's vesicular pore structure and morphology, characterized by an apparent density of 65.69 kg/m 3 , a porosity of 85.58%, a pore diameter of 0.96 ± 0.17 mm, a compressive strength of 0.015 MPa, and optimal thermal stability when the L-Tyr content was 3%. Additionally, L-Tyr enhanced the water absorption and retention capabilities, as well as the degradation performance of the material, achieving a maximum water absorption factor of 12.524 g/g. The degradation rate was found to be 10.95% after 6 months of degradation by N435 lipase, indicating that the material is environmentally friendly upon disposal. As a lettuce growing substrate, the LTPPPK material showed a 7.90% and 9.34% growth in root whisker and leaf width compared with the unmodified one after 42 days of lettuce growth, and the content of chlorophyll and soluble protein increased by 4.46% and 16.42%. It was shown that LTPPPK material can provide a certain amount of nitrogen and potassium for plant growth when used as lettuce cultivation substrate.
