To study the chemical constituents from Cissus assamica and obtain a more comprehensive understanding of its effective components.
Compounds were isolated by various column chromatographies with silica gel. Their structures were elucidated by spectral analysis (IR, MS, 1H-NMR, 13C-NMR) and chemical evidence.
Eight compounds were isolated and elucidated as ursolic acid (I), lupeol (II), n-hexacosinc acid (III), isolariciresinol-9-O-beta-D-glucopyranoside (IV), dauco sterin (V), 3,3'-dimethyl ellagic acid (VI), beta-Sitosterol (VII), bergenin (VIII).
Among these compounds, I-V are isolated from this plant for the first time.
研究锡金白粉藤的化学成分，更全面地了解其有效成分。
采用多种硅胶柱色谱法分离化合物。通过光谱分析（红外光谱、质谱、¹H-核磁共振、¹³C-核磁共振）和化学证据阐明其结构。
分离鉴定出8个化合物，分别为熊果酸（Ⅰ）、羽扇豆醇（Ⅱ）、正二十六碳酸（Ⅲ）、异落叶松脂素-9-O-β-D-吡喃葡萄糖苷（Ⅳ）、胡萝卜苷（Ⅴ）、3,3'-二甲基鞣花酸（Ⅵ）、β-谷甾醇（Ⅶ）、岩白菜素（Ⅷ）。
这些化合物中，Ⅰ-Ⅴ为首次从该植物中分离得到。
