Five flavonols, four flavones and one C-glycosylflavone were isolated from the leaves of Cathcartia villosa which is growing in the Himalayan Mountains. They were characterized as quercetin 3-O-vicianoside (1), quercetin 7,4′-di-O-glucoside (3), quercetin 3-O-rutinoside (4), quercetin 3-O-glucoside (5), quercetin 3-O-arabinosylarabinosylglucoside (6) (flavonols), luteolin (7), luteolin 7-O-glucoside (8), apigenin (9), chrysoeriol (10) (flavones), and vicenin-2 (11) (C-glycosylflavone) by UV, LC-MS, acid hydrolysis, NMR and/or HPLC and TLC comparisons with authentic samples. On the other hand, two flavonols 1 and kaempferol 3-O-vicianoside (2) were isolated and identified from the flowers of the species. Flavonoids were reported from the genus Cathcartia in this survey for the first time. Their chemical characters were chemotaxonomically compared with those of related Papaveraceous genera, Meconopsis and Papaver.

从喜马拉雅山上生长的长毛C叶中分离出了五种黄酮醇，四种黄酮和一种C-糖基黄酮。它们表征为槲皮素-3- ö -vicianoside（1），槲皮素7,4'-二- Ö葡糖苷（3），槲皮素-3- ø -rutinoside（4），槲皮素-3- ø葡糖苷（5），槲皮素3- O-阿拉伯糖基阿拉伯糖基葡糖苷（6）（黄酮醇），木犀草素（7），木犀草素7- O-葡糖苷（8），芹菜素（9），金绿宝石油（10）（黄酮）和Vicenin-2（11）（C-糖基黄酮）通过UV，LC-MS，酸水解，NMR和/或HPLC和TLC与真实样品进行比较。另一方面，从该物种的花中分离并鉴定出两种黄酮醇1和山奈酚3- O- vicianoside（2）。在这项调查中，首次报道了车ath属中的类黄酮。在化学分类学上将它们的化学特性与相关罂粟属，Meconopsis和Papaver进行了化学分类。
