Two new hexenol glycosides, ()-hex-3-en-1-ol O--d-xylcopyranosyl-(1-6)- -d-glucopyranosyl-(1-2)--d-glucopyranoside () and ()-hex-3-en-1-ol O--d-xylcopyranosyl-(1-6)--d-glucopyranosyl-(1-2)--d-glucopyranoside (2), were isolated from the 50% ethanol elution of macroporous resin of var. . Their structures were established by detailed spectroscopic analysis, including extensive 2D-NMR data. This is the first time to report the () and () 3-hexenol glycosides from var. .
从 var. 的大孔树脂 50%乙醇洗脱部分分离得到两个新的己烯醇糖苷，（）-己-3-烯-1-醇 O--d-木糖基-(1-6)- -d-吡喃葡萄糖基-(1-2)--d-吡喃葡萄糖苷 () 和（）-己-3-烯-1-醇 O--d-木糖基-(1-6)--d-吡喃葡萄糖基-(1-2)--d-吡喃葡萄糖苷 (2)。通过详细的光谱分析，包括广泛的 2D-NMR 数据，确定了它们的结构。这是首次从 var. 中报道（）和（）3-己烯醇糖苷。
