Individuals infected with COVID-19 often experience the distressing discomfort of pharyngitis. Thus, it is crucial to develop novel drugs to improve therapeutic options. In this study, we investigated the interaction between bioactive compounds isolated from Acanthopanax trifoliatus (L.) Merr and proteins associated with COVID-19 and pharyngitis through in silico analysis. Several molecules demonstrated high affinities to multiple targets, indicating significant potential for alleviating pharyngitis and other COVID-19-related symptoms. Among them, rutin and isochlorogenic acid C, two major components in Acanthopanax trifoliatus (L.) Merr ethanol extracts, were further experimentally demonstrated to exhibit strong inhibitory effects against SARS-CoV-2 and to possess significant anti-inflammatory activities. Inhibition of over 50% in several key genes was observed, demonstrating the efficacy of in silico methods in identifying high-affinity target binders. Our findings provide a theoretical foundation for the development of Acanthopanax trifoliatus (L.) Merr as a novel multi-target therapeutic agent for both COVID-19 and pharyngitis.

Acanthopanax trifoliatus (L.) Merr (AT) is a medicinal and edible plant with high nutritional value. The biological activity of A. trifoliatus (L.) Merr and its basis for injury treatment are explored in this paper. AT was ethanol-extracted then refined separately with petroleum ether, chloroform, ethyl acetate, and n-butanol. Active ingredients were analyzed, and anti-bacterial, anti-inflammatory, analgesic, and hemostatic effects were explored. Petroleum ether layer (PEL) extract produced the strongest antibacterial effect. Ethyl acetate layer (EAL) extract had the highest active substance content, with strong hemostatic and analgesic activities. Chloroform layer (CL) extract had the strongest anti-inflammatory effect and significantly reduced IL-1β protein expression. Active ingredients were analyzed using HPLC and UPLC-MS to determine saponin, polyphenol, flavonoid, and characteristic ingredient contents. EAL extract had the highest polyphenol and flavonoid levels, including rutin, chlorogenic acid, isochlorogenic acid A, and isochlorogenic acid C, which may contribute to its nutritional activities. The study provides a reliable theoretical and practical basis for the applications of AT nutraceutical products.

Stems and leaves of Acanthopanax trifoliatus (L) Merr (AT) are commonly used as an edible vegetable in China. The scientific basis of antioxidant and antiinflammatory activities of AT was investigated. The polyphenol contents and free radical scavenging activities of AT ethanol extracts (EAT) were determined. Chlorogenic acid, isochlorogenic acid A, isochlorogenic acid C, and rutin were identified as major components in EAT. LPS-induced NO production in RAW264.7 cells was decreased significantly ( p <0.05) after EAT treatment, compared with controls. In vivo studies indicated that EAT had more activity than chlorogenic acid per mg of dry weight for inhibition of TPA-induced ear edema. TPA-induced increases in cytokine production (TNF-α, IL-6, MMP-9, and TIMP-1) were significantly ( p <0.05) reduced by EAT treatment, compared with controls. EAT exerts anti-inflammatory activities probably due, at least in part, to chlorogenic acid.

This study aimed to establish a bidirectional fermentation system using Tremella fuciformis and Acanthopanax trifoliatus to promote the transformation and utilization of the synthesized antioxidant metabolites from fermentation supernatant. The effect of fermentation conditions on the total phenolic content was investigated using response surface methodology in terms of three factors, including temperature (22-28°C), pH (6-8), and inoculum size (2-8%, v/v). The optimized fermentation parameters were: 28°C, pH 8, and an inoculum size of 2%, which led to a maximum total phenolic content of 314.79 ± 6.89 μg/mL in the fermentation supernatant after 24 h culture. The content of total flavonoids and polysaccharides reached 78.65 ± 0.82 μg/mL and 9358.08 ± 122.96 μg/mL, respectively. In addition, ABTS+, DPPH⋅, and ⋅OH clearance rates reached 95.09, 88.85, and 85.36% at 24 h under optimized conditions, respectively. The content of total phenolics, flavonoids and polysaccharides in the optimized fermentation supernatant of T. fuciformis - Acanthopanax trifoliatus increased by 0.88 ± 0.04, 0.09 ± 0.02, and 33.84 ± 1.85 times that of aqueous extracts from A. trifoliatus , respectively. Simultaneously, 0.30 ± 0.00, 0.26 ± 0.01, and 1.19 ± 0.12 times increase of antioxidant activity against ABTS+, DPPH⋅, and ⋅OH clearance rates were observed, respectively. Additionally, the metabolite composition changes caused by fermentation were analyzed using ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) based on untargeted metabolomics and the phytochemical profile of fermentation supernatant differentiated significantly based on unsupervised principal component analysis (PCA) during fermentation from 24 to 96 h. Furthermore, a significant increase in antioxidant phenolic and flavonoid compounds, such as ellagic acid, vanillin, luteolin, kaempferol, myricetin, isorhamnetin, and (+)-gallocatechin, was observed after fermentation. Thus, these results indicated that the fermentation broth of T. fuciformis and A. trifoliatus had significant antioxidant activity, and may have potential application for health products such as functional beverages, cosmetics, and pharmaceutical raw materials.

SHAUE method rapidly extracts saponins via synergistic mechanical, osmotic, and cavitation effects. • Homogenization disrupts cell walls, increasing surface area for saponin release. • Salt-assisted and ultrasound steps enhance mass transfer and extraction efficiency. • D-101 macroporous resin realizes effective saponin purification, yielding high-purity products. A salt-enhanced homogenization-assisted ultrasonic extraction (SHAUE) method was developed for the efficient extraction of total saponins from Acanthopanax trifoliatus (ATS). The introduction of NaCl effectively modulated solvent polarity and disrupted saponin–matrix interactions, while homogenization and ultrasonic cavitation synergistically enhanced cell wall rupture and mass transfer. Under optimal conditions, the extraction yield of total saponins reached 3.29% with a purity of 22.50%, both of which were significantly higher than those obtained by conventional heat-reflux extraction (HRE). For further purification, D-101 macroporous resin was selected owing to its favorable adsorption–desorption behavior toward saponins, resulting in a marked increase in saponin purity from 22.50% to 62.57%. The main components of the purified saponins (PATS) were characterized and identified by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). In vitro bioactivity assays revealed that the PATS exhibited significant anti-inflammatory activity in LPS-induced RAW264.7 macrophages. This study provides a green and efficient approach for the extraction of saponins, and offers a theoretical basis and technical support for the further development and application of saponins in functional foods and anti-inflammatory products Download: Download high-res image (398KB) Download: Download full-size image

Objectives: To evaluate the Spectrum-Effect relationships between the High-Performance Liquid Chromatography (HPLC) Fingerprints of fractions with different polarities and the anti-inflammatory and antioxidant effects of A. trifoliatus and to identify its pharmacodynamic material basis.Materials and Methods: Chemical Fingerprints of A. trifoliatus fractions with different polarities (all fractions and ethyl acetate, n-butanol and water fractions) were obtained by HPLC, and Principal Component Analysis (PCA) was performed. The foot swelling and prostaglandin E2 (PGE2) content in mice induced by carrageenan were used as anti-inflammatory markers, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) methods were used as antioxidant indicators. Moreover, the Spectrum-Effect relationship between common peaks and efficacy value was conducted by Grey Relational Analysis (GRA) and Partial Least Squares analysis (PLS).Results: PCA identified three principal components, and all fractions of A. trifoliatus had good anti-inflammatory and antioxidant effects. Based on GRA and PLS analysis, peaks 1 and 2 (neochlorogenic acid), 4 and 5 (chlorogenic acid), 8, 9, 10, 11 (isochlorogenic acid B), and 12 were involved in anti-inflammatory efficacy, and peaks 1 and 2 (neochlorogenic acid), 3, 4, and 5 (chlorogenic acid), and 6, 7, 9, 10, and 13 (isochlorogenic acid A) were involved in antioxidant efficacy.Conclusion: This study on the Spectrum-Effect relationship of different polar fractions of A. trifoliatus provides data to support the discovery of the pharmacodynamic material basis of the anti-inflammatory and antioxidant properties of A. trifoliatus.

Five terpenoids ( 1 – 5 ) from a vegetable plant Acanthopanax trifoliatus (L.) Merr. were investigated for their effects on human prostate cancer cells. The diterpenoid ( 3 ) and triterpenoids ( 4 and 5 ) were found to inhibit the growth and stimulate apoptosis in PC-3 cells. The effects of these terpenoids on PC-3 cells were associated with strong suppression of nuclear factor-κB (NF-κB) and signal transducer and activator of transcription 3 (STAT3). These terpenoids also inhibited the expression of survivin, a downstream target of NF-κB and STAT3. The in vivo study using a xenograft mouse model showed that 5 strongly inhibited the formation and growth of PC-3 tumours. Moreover, treatment with 5 strongly decreased the expression of phospho-STAT3 and survivin in PC-3 tumours. Our results indicate that 5 has preventive efficacy on the development of PC-3 xenograft tumours. This terpenoid may serve as a candidate for future development as a novel agent for prostate cancer prevention.

Increasing numbers of studies suggest that short-chain fatty acids (SCFAs) are closely related to diabetes. However, the complexity of fecal pretreatment makes the detection of SCFAs in feces relatively difficult. In this study, we established a sample pretreatment protocol that involved no tedious steps, requiring only the grinding of appropriate amounts of feces into powder in liquid nitrogen. The SCFA content in feces was then detected using the headspace-gas chromatography (HS-GC) method. The method achieved good linearity ( R 2 ≥ 0.9940), and the limits of quantification (LOQs) and detection (LODs) of all investigated SCFAs ranged from 0.15 to 0.45 mM and 0.05 to 0.15 mM, respectively. The recoveries of the SCFAs ranged from 91.55 to 103.96% in mouse fecal samples. The HS-GC method was then applied to evaluate the effects of a neutral polysaccharide from Acanthopanax trifoliatus (ATP1-1) on the fecal SCFA content in streptozotocin (STZ)-induced diabetic mice. After 6 weeks of treatment with 140 mg/kg/d ATP1-1, the expression levels of acetic acid, propionic acid, butyric acid, isobutyric acid, isovaleric acid and valeric acid were increased by 215.4, 88.8, 95.3, 300.8, 260.7 and 158.0%, respectively, which indicated that the hypoglycemic effect of ATP1-1 may be related to its impact on SCFAs. Our simplified pretreatment of fecal samples is suitable for the analysis and detection of SCFAs in mouse feces by HS-GC.
