Phytochemical characterization of CP
Phytochemical compositions of the CP were clarified by using high performance liquid chromatography (HPLC). The 5 components in the CP were identified in the chromatogram with peaks at 17.19 min to3-cafeoylquinic acid, 20.19 min to isoquercitrin, 22.19 min to kaempferol-3-glucoside, 23.43 min to kaempferol 3-rhamnoside, 27.56 min to quercetin by the comparison to external standards (
