Two new flavonol glycosides were isolated from the 1-butanol (1-BuOH)-soluble fraction of a methanol (MeOH) extract of the leaves of Indigofera zollingeriana, along with four flavonol glycosides and three known megastigmane glucosides. The structures of the new compounds were elucidated by spectroscopic analyses as kaempferol 3-O-β-D-(2"-O-β-D-apiofuranosyl)glucopyranoside 7-O-α-L-rhamnopyranoside and 3-O-β-D-(2"-O-β-D-apiofuranosyl, 6"-O-α-L-rhamnopyranosyl)glucopyranoside 7-O-α-L-rhamnopyranoside.
从菘蓝叶甲醇提取物的正丁醇（1-BuOH）可溶部分中分离得到两种新的黄酮醇糖苷，以及四种黄酮醇糖苷和三种已知的megastigmane 葡萄糖苷。通过光谱分析阐明了新化合物的结构，分别为山柰酚 3-O-β-D-（2"-O-β-D-吡喃阿洛糖苷基）葡萄糖苷 7-O-α-L-鼠李吡喃糖苷和 3-O-β-D-（2"-O-β-D-吡喃阿洛糖苷基，6"-O-α-L-鼠李吡喃糖苷基）葡萄糖苷 7-O-α-L-鼠李吡喃糖苷。
