Abstract

Houttuynia cordata Thunb., a traditional medicinal plant with a variety of pharmaceutical activities. In this study, antioxidant activities of extracts obtained from flower, leaf, stem, and root of two H. cordata accessions and their contents of phenolic compounds and flavonoids were evaluated. Results indicated that the total phenolic contents ranged from 1.90 to 10.26 mg gallic acid g-1 dw. The flavonoid contents were between 0.751 to 12.4 mg rutin g-1 dw. The results indicated that the total phenolic and flavonoid contents, as well as antioxidant activities, as observed in flower and leaf were generally higher than that in root and stem. The two H. cordata accessions tested showed no significant difference within antioxidant activities. Therefore, we recommend using the leaf and flower of H. cordata as potential natural antioxidant for food and medical products.

 

Key words: Houttuynia cordata Thunb., phenolics, flavonoid, antioxidant activity.
