A new indole alkaloidal glucoside together with three known compounds aurantiamide acetate (2), eleutheroside E (3) and 1-O-caffeoyl-β-D-glucopyranoside (4) has been isolated from ethanol extract of the aerial parts of Clematis terniflora DC. On the basis of their spectroscopic and chemical evidence, the new compound was elucidated as (6-O-β-D-glucopyranosyl-1H-indol-3-yl) carboxylic acid methyl ester (1). Compounds 1 and 3 showed significant cytotoxicity against human ECA-109.
从Clematis terniflora DC 的地上部分的乙醇提取物中分离得到一个新的吲哚生物碱苷和三个已知化合物：aurantiamide 乙酸酯（2）、eleutheroside E（3）和 1-O-咖啡酰-β-D-吡喃葡萄糖苷（4）。根据它们的光谱和化学证据，新化合物被阐明为（6-O-β-D-吡喃葡萄糖基-1H-吲哚-3-基）羧酸甲酯（1）。化合物 1 和 3 对人 ECA-109 表现出显著的细胞毒性。
