A new flavonol tetraglycoside, together with two known flavonol glycosides, kaempferol 7-rhamnoside and kaempferol 3-rhamnosyl(1-->6) galactoside-7-rhamnoside, were isolated from fresh plant material of Cephalocereus senilis. The structure of the new compound was established as kaempferol 3-O-beta-D-glucopyranosyl(1-->2)-O-[alpha-L-rhamnopyranosyl (1-->6)]-beta-D-galactopyranoside-7-O-alpha-L-rhamnopyranoside based on spectroscopic data. The whole plant flavonoid chemistry was strikingly different from that found previously in chitin-treated cell suspension cultures of the same plant.
从老年翁柱的新鲜植物材料中分离出一种新的黄酮醇四糖苷，以及两种已知的黄酮醇糖苷，山柰酚7-鼠李糖苷和山柰酚3-鼠李糖基（1→6）半乳糖苷-7-鼠李糖苷。根据光谱数据，新化合物的结构确定为山柰酚3-O-β-D-吡喃葡萄糖基（1→2）-O-[α-L-吡喃鼠李糖基（1→6）]-β-D-吡喃半乳糖苷-7-O-α-L-吡喃鼠李糖苷。该植物全株的黄酮类化学物质与之前在同一植物的几丁质处理细胞悬浮培养物中发现的显著不同。
