Stib. Methods Compounds were isolated by silica gel column chromatography and Sephadex LH-20 gel column chromatography, and the structures were identified by spectral analysis. Result Five compounds were identified as 3β, 6β, 23-trihydroxyolean-12-en-28-oic acid (1), ursolic acid (2), n-heptadecanoic acid (3), n-octadecanoic acid (4), and β-sitosterol (5). Conclusion Five compounds were isolated from the plant for the first time.展开更多
A new depside named salvianolic acid H was isolated from the aqueous extract of Salvia cavaleriei vat.simplicifolia,along with salvianolic acid A,B,C,isosalvianolic acid C,lithospermic acid, rosmarinic acid,R-(+)-β-(...A new depside named salvianolic acid H was isolated from the aqueous extract of Salvia cavaleriei vat.simplicifolia,along with salvianolic acid A,B,C,isosalvianolic acid C,lithospermic acid, rosmarinic acid,R-(+)-β-(3,4-dihydroxyphenyl)lacticacid and protocatechualdehyde.Rosmarinic acid was obtained as the major component.展开更多
A new lignan glycoside, named (7S,8R,8'R)-(-)-lariciresinol-9-O-a-L-rhamnopyranosyl (1-2) 13-D-glucopyranoside (1),was isolated from the ethanol extract ofPilea cavaleriei Levi subsp, cavaleriei, together wit...A new lignan glycoside, named (7S,8R,8'R)-(-)-lariciresinol-9-O-a-L-rhamnopyranosyl (1-2) 13-D-glucopyranoside (1),was isolated from the ethanol extract ofPilea cavaleriei Levi subsp, cavaleriei, together with 17 known lignans (2-18). The structuresof these compounds were elucidated by extensive spectroscopic analysis, including 1D NMR, 2D NMR and HR-ESI-MS.All the compounds were obtained from the genus Pilea for the first time.展开更多
