对新热带Cavendishia属116种植物的叶片进行了调查，结果表明该属植物以黄酮c -苷的存在为特征。其他成分包括黄酮类（木犀草素、黄菊醇和tricin）、黄酮醇（槲皮素、山奈酚和杨梅素）、二氢黄酮醇、原花青素和鞣花酸或水杨酸。在6种植物中发现了二苯乙烯，白藜芦醇，这是该家族中仅有的第二份报告。一种天然杂交种的身份鉴定。通过对两种亲本植物的叶片特征酚类物质的检测，证实了槲皮的存在。
A survey of the leaves of 116 spp. of the neotropical genus Cavendishia shows that the genus is characterized by the presence of flavone C-glycosides. Other constituents include flavones (luteolin, chrysoeriol and tricin), flavonols (quercetin, kaempferol and myricetin), dihydroflavonols, proanthocyanidins, and ellagic or salicylic acids. The stilbene, resveratrol, is identified in 6 spp., this is only the 2nd report of stilbenoids in the family. The identity of a natural hybrid C. endresii .times. C. quereme is confirmed by detecting in its leaves characteristic phenolics of both parental species.
