Results: Aqueous extract of PSL at a dose of 500 mg kg-1 (based on previous experience), along with different concentrations of the above four functional ingredients (189.86 µg kg-1 linalool, 114.75 mg kg-1 5-hydroxy-4',7-dimethoxyflavanone, 32.4mg kg-1 2'-O-methylisoliquiritigenin and 44.44 mg kg-1 ferulic acid), had a sedative-hypnotic effect by affecting neurotransmitter levels in mice.
Conclusion: The data demonstrate that these four ingredients are the key functional factors for the sedative-hypnotic and anxiolytic effects of PSL aqueous extracts and that these effects occur via changes in neurotransmitter levels and pathways.

| Additional Infomation |
2'-O-methylisoglycyrrhizin belongs to the chalcone class of compounds. Its structure is similar to isoliquiritigenin, except that a hydroxyl group at the 2' position is replaced by a methoxy group. It is a metabolite. It belongs to the chalcone, monomethoxybenzene, and phenolic compounds. Its function is related to isoliquiritigenin. 2'-O-methylisoglycyrrhizin has been reported to exist in Dracaena cochinchinensis, Dracaena cambodiana, and other organisms with relevant data. Peanut stems and leaves (PSL) have traditionally been both a specialty food and a medicinal herb in Asia. Classical Chinese literature records the sedative, hypnotic, and anti-anxiety effects of peanut stems and leaves, a fact confirmed by many other researchers in recent years. In previous studies, we used ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC/QTOF-MS) to screen out four sleep-related components (linalool, 5-hydroxy-4',7-dimethoxyflavanone, 2'-O-methylisoglycyrrhizin and ferulic acid), among which 5-hydroxy-4',7-dimethoxyflavanone and 2'-O-methylisoglycyrrhizin are newly discovered components in peanut plants. In this study, we performed quantitative analysis on the above four components. At the same time, we also conducted several basic functional studies on mice, including motor activity, direct sleep test, pentobarbital-induced sleep time test, subthreshold dose pentobarbital test and sodium barbital sleep latency test, to determine the material basis of the sedative-hypnotic and anti-anxiety effects of peanut water extract. In addition, in order to elucidate its exact mechanism of action, we used ultra-high performance liquid chromatography-triple quadrupole mass spectrometry (UHPLC/QQQ-MS) to determine the neurotransmitter levels in three brain regions (cerebrum, cerebellum and brainstem).

| Solubility (In Vitro) |
DMSO: 100 mg/mL (369.99 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.25 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 3.6999 mL | 18.4993 mL | 36.9987 mL | |
| 5 mM | 0.7400 mL | 3.6999 mL | 7.3997 mL | |
| 10 mM | 0.3700 mL | 1.8499 mL | 3.6999 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
