Two new flavonol triglycosides, kaempferol 3-omicron-alpha-L-rhamnopyranosyl(1->2)-beta-D-galactopyranoside-7-O- alpha-L-arabinofuranoside and kaempferol 3-O-alpha-rhamnopyranosyl(1-->6)-beta-D-galactopyranoside-7-O- alpha-L-arabinofuranoside were isolated from the flowers of Indigofera hepepetala, together with three known glycosides, kaempferol 3-omicron-alpha-L-arabinopyranoside-7-O-alpha-L-rhamnopyranoside, kaempferol 3-O-alpha-L-rhamnopyranoside-7-O-alpha-L-arabinopyranoside and kaempferol 7-rhamnoside. The structures were determined by means of Rf values, UV, EI-mass spectrometry, FAB-mass spectrometry, 1H NMR, 13C (B.B and DEPT) NMR, NOE difference measurement and 1H-1H COSY spectral data.
从苏门答腊木蓝的花中分离出两种新的黄酮醇三糖苷，山柰酚3 - O - α - L - 鼠李吡喃糖基(1→2)-β - D - 吡喃半乳糖苷 - 7 - O - α - L - 阿拉伯呋喃糖苷和山柰酚3 - O - α - 鼠李吡喃糖基(1→6)-β - D - 吡喃半乳糖苷 - 7 - O - α - L - 阿拉伯呋喃糖苷，以及三种已知糖苷，山柰酚3 - O - α - L - 阿拉伯吡喃糖苷 - 7 - O - α - L - 鼠李吡喃糖苷、山柰酚3 - O - α - L - 鼠李吡喃糖苷 - 7 - O - α - L - 阿拉伯吡喃糖苷和山柰酚7 - 鼠李糖苷。通过比移值、紫外光谱、电子轰击质谱、快原子轰击质谱、1H核磁共振、13C（宽带去偶和DEPT）核磁共振、核Overhauser效应差值测量以及1H - 1H化学位移相关谱数据确定了这些化合物的结构。
