In addition to four known glycosides, icariin, epimedin B, epimedosides A and E, two new glycosides of a flavonol with a gamma,gamma-dimethylallyl group were isolated from the underground parts of Vancouveria hexandra. The structures were determined to be des-O-methyl-anhydroicaritin 3-O-beta-D-xylopyranosyl(1----2)-alpha-L-rhamnopyranoside 7-O-beta-D-glucopyranosyl(1----2)-beta-D-glucopyranoside and anhydroicaritin 3-O-alpha-L-rhamnopyranosyl(1----3)-alpha-L-rhamnopyranoside 7-O-beta-D-glucopyranoside by means of spectral analysis.
除了四种已知的糖苷，淫羊藿苷、朝藿定B、淫羊藿苷A和淫羊藿苷E外，还从六角莲的地下部分分离出两种带有γ,γ-二甲基烯丙基的黄酮醇新糖苷。通过光谱分析确定其结构分别为去-O-甲基脱水淫羊藿素3-O-β-D-吡喃木糖基(1→2)-α-L-吡喃鼠李糖苷7-O-β-D-吡喃葡萄糖基(1→2)-β-D-吡喃葡萄糖苷和脱水淫羊藿素3-O-α-L-吡喃鼠李糖苷(1→3)-α-L-吡喃鼠李糖苷7-O-β-D-吡喃葡萄糖苷。
