BACKGROUND Insomnia, a prevalent sleep disorder, detrimentally affects quality of life and is often challenging to manage with conventional treatments. This study delved into identifying and quantifying the main compounds by employing ultra-performance liquid chromatography–Q-Exactive-Orbitrap mass spectrometry, and further to evaluate the therapeutic potential of Rosa roxburghii folium (RRF) extract, with multiple pharmacological activities. Previous research had hinted at the efficacy of glycosides in influencing the γ -aminobutyric acid (GABAergic) system, which plays a pivotal role in sleep regulation. Utilizing a p -chlorophenylalanine-induced insomnia model in BALB/C mice, this investigation aimed to unravel the effects of various dosages of RRF extract on sleep quality and elucidated its mechanism of action. RESULTS A total of 66 compounds in the RRF extract were analyzed. Behavioral assessments demonstrated notable enhancements in sleep duration and latency. Biochemical analyses further corroborated these findings, revealing modulation in neurotransmitter levels indicative of a potential mechanism through the GABAergic and serotoninergic pathways. Additionally, histological evaluations suggested anti-inflammatory and antioxidant effects of the RRF extract. CONCLUSION The findings from this study underscored the therapeutic efficacy of RRF extract in combating insomnia, particularly highlighting its glycoside components’ role. The extract's significant improvement in sleep duration and latency, alongside its modulation of neurotransmitter levels, showcases its potential as a natural remedy for insomnia. Through its action on the GABAergic and serotoninergic pathways, as well as its anti-inflammatory and antioxidant effects, RRF extract emerges as a promising candidate for insomnia treatment, offering a holistic approach to sleep disorder management. © 2024 Society of Chemical Industry.

Geochemical fluoride pollution is a global public health issue affecting a wide range and large population. The major health hazard from long-term fluoride exposure is skeletal fluorosis, a highly disabling and irreversible bone damage disease with no effective early interventions available to date. Given reactive oxygen species (ROS) accumulation is a key event in fluoride-induced bone damage, we established a sodium fluoride-exposed rat model. During the phase when fluoride induced ROS accumulation and mild bone damage in rat bone tissue, we administered Rosa roxburghii Tratt juice (RRTJ)—a natural food-medicinal homologous plant with antioxidant properties—to explore its intervention effect and potential mechanism against fluoride-induced bone damage. Results showed RRTJ inhibited fluoride-induced decreases in bone mineral density and trabecular number in male rats. Since enhanced bone resorption mediated by osteoclast overactivation is the initiating link of these fluoride-induced pathological changes, this study further found RRTJ suppressed fluoride-induced increases in osteoclast activity in male rat bone tissue, specifically reducing osteoclast numbers in bone tissue and lowering serum levels of bone resorption markers CTX and TRAP-5b. This effect is achieved by RRTJ scavenging fluoride-induced ROS accumulation in bone tissue, restoring ROS/TNF-α/NF-κB pathway homeostasis, and thereby inhibiting the overexpression of osteoclast activation-related genes tartrate-resistant acid phosphatase and cathepsin K. In conclusion, this study confirms RRT inhibits fluoride exposure-induced bone damage in male rats by regulating ROS/TNF-α/NF-κB pathway homeostasis. These findings provide new perspectives on the mechanism of fluoride-induced bone damage and, more importantly, reveal a potential novel intervention strategy.

An extraction assay applying microwave-assisted enzymatic treatment for polysaccharides in Rosa roxburghii was developed using response surface methodology. The process parameters were optimized using Plackett-Burman (PB) design and central composite design to enhance the Rosa roxburghii polysaccharide extraction yield. Specific conditions (microwave power, 575 W; microwave time, 18 min; liquid-to-material ratio, 13.5:1 mL/g; and enzyme dose, 6.5 g/mL) generated an experimental yield of 36.21 ± 0.62%, which closely agreed with the predicted value of 35.75%. Purification with a DEAE-52 cellulose column generated two fractions, PR-1 (from 6.2 × 10 3 to 7.4 KDa) and PR-2 (from 559.8 to 106.6 KDa). Subsequently, the antioxidant activity and α- d -glucosidase inhibitory activity of the two polysaccharide fractions were assessed; PR-1 exhibited stronger antioxidant activity and α- d -glucosidase inhibitory activity than PR-2. Finally, the monosaccharide composition of PR-1 was determined by HPLC using a 1-phenyl-3-methyl-5-pyrazolone precolumn derivatization method. The result showed that PR-1 contained mannose , ribose , rhamnose , glucosamine hydrochloride, glucuronic acid , galacturonic acid, glucose, galactose , arabinose and fucose with molar percentages of 2.1%, 0.54%, 2.1%, 0.26%, 1.5%, 22.7%, 24.0%, 26.4%, 19.6% and 0.89%, respectively.

This study aimed to investigate the dissipation, residues and dietary assessment of kresoxim-methyl in the application of Rosa Roxburghii and soil field using liquid chromatography-tandem mass spectrometry (LC–MS/MS). The results show that kresoxim-methyl in R. roxburghii samples was extracted by acetonitrile and purified by ethyl enediamine-N-propylsilane (PSA), while kresoxim-methyl in soil samples was extracted by acetonitrile and purified by octadecylsilyl solid phase dispersant (C 18 ). 0.1% formic acid (v/v)-water–methanol solution was used as the mobile phase, LC–MS/MS exhibited a good linearity in the range of 0.001–10 mg L −1 . The recoveries of R. roxburghii and soil matrix were 82.48%–102.55%, and the relative standard deviation ( RSD) were 1.13%–4.21%. The limit of detection ( LOD ) and quantification ( LOQ ) of kresoxim-methyl in R. roxburghii and soil samples was 0.50 and 0.60 µg kg −1 , respectively. The dissipation dynamics of kresoxim-methyl in R. roxburghii and soil followed the first-order kinetics, with the half-life of 4.28 and 4.41 days, respectively. The terminal residual amount of kresoxim-methyl in R. roxburghii and soil samples was 0.003–1.764 and 0.007–2.091 mg kg −1 , respectively. The dietary intake risk assessment indicates that a risk quotient ( RQ ) for kresoxim-methyl based on the national estimated daily intake ( NEDI ) of 0.1995 mg was 0.79%, suggesting that the use of kresoxim-methyl on R. roxburghii at recommended dosage was safe to consumers. This study provides the theoretical basis for guiding the rational use of kresoxim-methyl in the production of R. roxburghii .

Inhibitory effects (IEs) of flavonoids from Rosa roxburghii and R. sterilis fruits against α-glucosidase were investigated. Crude extract of R. roxburghii fruits ( Rr CE) and R. sterilis fruits ( Rs CE) were extracted with ethanol. The n-butanol extraction of aqueous Rr CE dispersion ( Rr CE - B) showed the greatest inhibition of α-glucosidase. The most abundant three components in Rr CE - B were kaempferol hexose, rutin, and catechin (Cat). The predominant active compounds were characterized as flavonoids by UV–vis spectra. Combination analysis suggested that Rr CE was a favorable choice to combine with acarbose (Aca). After simulated gastric digestion, IEs of flavonoids decreased greatly, especially when sodium nitrite was supplemented in the simulated gastric fluid (SGF). The UV–vis spectra indicated that flavonoids were basically stable in the SGF without sodium nitrite, but were oxidized by the HNO 2 , a natural component in the gastric fluid. The results of this study will help food scientists design special foods for diabetic patients.

Depression is a common mental disorder that substantially impairs patients’ daily life and work. To identify natural and safe preventive options, we investigated the preventive effect and underlying mechanism of theGanoderma lucidumandRosa roxburghiiTratt formula (GLRRTF) on depression. A total of 72 chemical components in GLRRTF were identified by UHPLC-ESI-Q-Exactive Plus Orbitrap-MS Analysis. GLRRTF (containing 400 mg/kg ofG. lucidumextract and 800 mg/kg ofR. roxburghiiextract per day), administered as a 1-week preventive intervention followed by 4 weeks of co-administration with chronic unpredictable mild stress, prevented the development of depression-like behaviors in male C57BL/6J mice and reduced neuronal damage in the hippocampus. Airflow-assisted desorption electrospray ionization mass spectrometry imaging and enzyme-linked immunosorbent assays showed that GLRRTF corrected abnormalities in neurotransmitter levels. The 16S rRNA sequencing indicated that GLRRTF restored dysbiosis of the gut microbiota. Metabolomic profiling revealed that GLRRTF increased the level of tryptophan and promoted tryptophan metabolism towards the 5-HT and indole pathways in feces and the brain. Western blot demonstrated that GLRRTF increased 5-HT production from tryptophan in the brain by regulating tryptophan hydroxylase 2 and DOPA decarboxylase. GLRRTF activated the PI3K/AKT pathway by regulating brain-derived neurotrophic factor and its receptor tropomyosin receptor kinase B. This research provides a comprehensive mechanistic understanding of GLRRTF’s preventive effect against depression, highlighting its potential as a novel, safe, and preventive functional food formulation.
