To study the chemical constituents from the roots of Craibiodendron henryi.
Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectral methods.
Twelve compounds were isolated from the ethyl acetate soluble fraction of the 95% ethanolic extract and their struc- tures were elucidated as quercetin (1), quercetin-3-O-rhamnicoside (2), quercetin-3-O-arabinofuranoside (3), (-)-epicatechin (4), proanthocyanidin A-2 (5), procyanidin B-2 (6), (-)-isolariciresinol-2a-O-beta-D-xylopyranoside (7), lyoniside (8), sitoster-yl-3beta-glucoside-6'-O-palmitate (9), beta-sitosterol (10), daucosterol (11) and octacosanoic acid (12).
Compounds 1-12 were isolated from this plant for the first time.
研究秀丽野海棠根的化学成分。
采用多种色谱技术分离纯化各成分。通过化学证据和光谱方法阐明其结构。
从95%乙醇提取物的乙酸乙酯可溶部分分离得到12个化合物，其结构分别鉴定为槲皮素（1）、槲皮素-3-O-鼠李糖苷（2）、槲皮素-3-O-阿拉伯呋喃糖苷（3）、（-）-表儿茶素（4）、原花青素A-2（5）、原花青素B-2（6）、（-）-异落叶松脂醇-2a-O-β-D-吡喃木糖苷（7）、里昂苷（8）、β-谷甾醇-3β-葡萄糖苷-6'-O-棕榈酸酯（9）、β-谷甾醇（10）、胡萝卜苷（11）和二十八烷酸（12）。
化合物1 - 12均为首次从该植物中分离得到。
