Phytochemical investigation of the native American plant led to the isolation of three new and eight known flavonol glycosides. The structures of the new compounds were established primarily by spectroscopic data as quercetin 3--(2″--α-l-rhamnopyranosyl-6″----coumaroyl)-β-D-glucopyranoside (), kaempferol 3--(2″--α-l-rhamnopyranosyl-6″----coumaroyl)-β-d-gluco-pyranoside () and quercetin 3--(2″--α--rhamnopyranosyl-6″----coumaroyl)-β-D-glucopyrano-side ().
对这种美洲本土植物进行的植物化学研究，导致分离出三种新的和八种已知的黄酮醇苷。新化合物的结构主要通过光谱数据确定为槲皮素3 - (2″ - α - l - 鼠李糖吡喃糖基 - 6″ - 香豆酰基) - β - D - 葡萄糖吡喃糖苷（）、山奈酚3 - (2″ - α - l - 鼠李糖吡喃糖基 - 6″ - 香豆酰基) - β - D - 葡萄糖吡喃糖苷（）和槲皮素3 - (2″ - α - 鼠李糖吡喃糖基 - 6″ - 香豆酰基) - β - D - 葡萄糖吡喃糖苷（）。
