水杨梅化学成分的研究(Ⅳ)

Studies on the Chemical Constituents of Thinleaf Adina (Adina rubella) (Ⅳ )

从水杨梅根中分得3个成分，经光谱和化学方法鉴定为；quinovicacid3β-O-β-D-fucopy-ranosyl－（28→1）β-D－glucopyranosylester（Ⅰ），quinovicacid3β－O－α－L－rhamnopyranosyl－（28→1）-β-D-glucopyranosylester（Ⅱ）和quinovicacid3β-O-β-D-glucopyranosyl（1→2）-β-D-glucopyra-noside（Ⅲ）。

Three compounds, quinovic acid 3β-O-β-D-fucopyranosyl- (28→1 )-β-D-glucopyranosyl ester (Ⅰ ),quinovic acid 3β-O-α-L-rhamnopyranosyl-(28→1)-β-D-glucopyranosyl ester (Ⅱ),quinovic acid 3β-O-β-D-glucopyranosyl (1→2)-β-D-glucopyranoside (Ⅲ),were isolated from roots of Adina rubella Hance. Their structures were established by chemical methods and spectral analysis. The three compounds were obtained from this genus for the first time.
