To study the lipoidal constituents of Setaria italica Beauv..Methods The constituents were isolated by chromatography and structurally elucidated on the basis of spectral analysis.Results The three glycerides were isolated as dilinolein (Ⅰ)， monolinolenin (Ⅱ)，α, β-digalactosyl-α′-linolenic-glyceride (Ⅲ).Conclusion These compounds were obtained from the plant for the first time. Compound Ⅲ is a new glycolipin.
ABSTRACT
Object To study the lipoidal constituents in Setaria italica (L ) Beauv Methods Individual compounds were isolated by chromatography and their structures elucidated by spectral analysis Results Two lipoidals were further isolated They were identified as glycerol-?, ?-dilinolenate-?′-rhamno-rhamnoside (Ⅰ) and 1-monoolein (Ⅱ) Conclusion The two compounds were obtained from this plant for the first time and compound Ⅰ is a new compound
ABSTRACT
Objective:To observe the analgesic effect of Yunzhi polysaccharopeptide (PSP) and analyze its mechanism. Methods: The hot plate test in mice and the tail stimulation vocalization test in rats were used.Results: PSP administered po at a dose of 1.0 g/kg for 7 days could produce a significant analgesic effect, which could last for more than two hours. The analgesic effect of PSP disappeared after lesion of mediobasal hypothalamus. Conclusions: PSP could elicit a central analgesic effect.
