contain, together with tecomoside, large quantities of it's benzoic and cinnamic esters. A novel glucoside was isolated and, by spectroscopic and chemical data, characterized as 7-O-(p-methoxy) benzoyl tecomoside. Flowers of T. capensis contain only tecomoside, together with two phenylethanoid-derived glucosides, cornoside and it's rearranged aglycone, halleridone, and rengioside B.
Tecoma capensis 的叶子与 tecomoside 一起含有大量的
苯甲酸酯和
肉桂酸酯。分离出一种新型
葡萄糖苷,并通过光谱和
化学数据表征为 7-O-(p-甲氧基) 苯甲酰 tecomoside。T. capensis 的花仅含有 tecomoside,以及两种
苯乙醇衍生的
葡萄糖苷、cornoside 及其重排的苷元、halleridone 和 rengioside B。
