Concentration of quercetin and soluble tannin in Houttuynia cordata were determined at different growth stages as well as plant parts and application amounts of compost. Both contents of quercetin and tannin at growth stages were decreased before flowering time but slightly increased after flowering. The both contents of components in Houttuynia cordata collected on April 20 were shown to be markedly increased compared to those collected in May or June. The contents of quercetin and tannin at different organs were the highest in the flower. In the experiment of application amounts of compost, as application amounts is increased, fresh weight of aerial part was increased but the contents of quercetin and tannin were decreased. The contents of quercetin and tannin were the highest with 0.67% and 2.3%, respectively, in the compost non-treatment.
