Seven glycosides were identified as kaempferol-3-O-α-L-rhamnopyranosyl(1→3)-[α-L-rhamnopyranosyl(1→6)]-β-D-galactopyranoside(I),kaempferol-3-O-rutinoside(II),7-ketologanin(III),oleoside-11-methyl ester(IV),7-gl.
从素馨花干燥花蕾70%乙醇提取物中分离得到7个糖苷类化合物,分别鉴定为山柰酚-3-O-α-L-吡喃鼠李糖基(1→3)-[α-L-吡喃鼠李糖基(1→6)]-β-D-吡喃半乳糖苷(I)、山柰酚-3-O-芸香糖苷(II)、7-ketologanin(III)、oleoside-11-methyl ester(IV)、7-glucosyl-11-methyl oleoside(V)、ligstroside(VI)、橄榄苦苷(VII)。
Methods The isolation and purification of glycosides were done with column chromatography on macro porous resin,polyamides and Sephadex LH-20,whilst the structure elucidation was done by HRCI-MS and NMR(1D and 2D) methods.
