Phytochemical analysis and correlation of total polyphenol content and antioxidant properties of Symplocos cochinchinensis leaves

This study screened phytochemicals to determine their total polyphenols content (TPC) by Folin-Ciocalteu reagents and to evaluate antioxidant activity using DPPH scavenging, ABTS cation decolorization, and reducing power assays of various extracts of Symplocos cochinchinensis leaves. A correlation between TPC and antioxidant activity was analysed by Pearson’s method.
