To study the estimate method of C. chinensis and C. australia.
HPLC was used to determine the contents of four kinds of flavones of C. chinensis and C. australia growing on different hosts.
C. chinensis and C. australia growing on different hosts both had hyperoside, quercetin, kaempferol and isorhamnetin. The content range of hyperoside was 2.790-6.502 mg/g and was higher than other flavones. The content ranges of quercetin, kaempferol and isorhamnetin were 0.025-0.176 mg/g, 0.001-0.213 mg/g and 0.001-0.077 mg/g, respectively.
The contents of hyperoside and quercetin are higher in C. chineasis than in C. australia. The contents of kaempferol and isorhamnetin are lower in C. chinensis than in C. australia. The hosts influence flavones content of C. chinensis and C. australia.
