In order to find out the content and pharmacological effects of the color related secondary metabolites in clematis hybridas, methods such as Folin-phenol method, vanillin-hydrochloric acid method, spectrophotometry were used to determine the content of total phenols, tannins, proanthocyanidins, flavonoids and anthocyanins in the calyx petals of 7 clematis hybridas varieties, and their pharmacological effects were studied and analyzed one by one. The results showed that 7 clematis hybridas varieties all accumulated abundant phenols and flavonoids in their calyx petals, with 6.51~8.50 mg/g and 1.15~3.04 mg/g, respectively, and also all accumulated a certain amount of tannins, proanthocyanidins and anthocyanins. The pharmacological analysis showed that the color related secondary metabolites (total phenols, tannins, proanthocyanidins, flavonoids and anthocyanins) in clematis hybridas all have good antioxidant activity and the ability to remove free radicals, which can effectively resist oxidation, anti-aging, remove free radicals in the body, protect cardiovascular and cerebrovascular systems, alleviate inflammation, inhibit cancer, etc. The implementation of this study has laid a foundation for ascertaining the medicinal value of the color related secondary metabolites in clematis hybridas, and also provided a theoretical basis for pharmaceutical development of secondary metabolites in the future.
