ABSTRACT
Objective:
To study the glycoside chemical constituents of Bletilla striata grown in Guizhou Province.Methods:
The glycoside chemical constituents were separated and purified by silica gel column chromatography, MCI, gel column chromatography, medium pressure preparation, highperformance liquid chromatography and other modern separation methods. The structures were identified based on the spectral data.Results:
Thirteen glycosides were isolated from the 95% ethanol extracts 1-methyl-3-phenylpropyl-β-D-glucopyranoside (1), 1-(4-β-D-glucopyranosyl oxybenzyl) 4-ethyl (2R)-2-isobutylmalate (2), 3’,5- dimethoxy-bibenzyl-3-O-β-D-glucopyranoside (3), syringaresinol mono-β-D-glucoside (4), 4-O-(6’-O-glucosyl-p-coumaroyl)-4- hydroxybenzyl alcohol (5), (4-hydroxyphenyl) methyl-β-D-glucopyranoside (6), 4-methylphenyl-β-D-glucopyranoside (7), benzyl-β-D- glucopyranoside (8), phenyl-β-D-glucopyranoside (9), 4-[(acetyloxy) methyl] phenyl-β-D-glucopyranoside (10), batatasin III-3-O- glucoside (11), gastrodin (12) and 4-(4-β-D-glucopyranosyl-oxybenzyl)-(2R)-2-isobutylmalate (13).Conclusion:
Compound 1 is a new natural product. Compounds 3-6 are isolated from this plant for the first time; Compounds 2, 7-13 are obtained from this genus for the first time.
