Effect of different polarity solvents on the anti-inflammatory activity of Symplocos cochinchinensis leaves and correlation with total polyphenol content

Abstract

Symplocos cochinchinensis leaves known as Vietnamese traditional herbal medicines which have been utilized anciently to support the medication of infirmities. The study aimed to explore the correlation of total polyphenol content (TPC) with anti-inflammatory activity of S. cochinchinensis leaves. S. cochinchinensis leaf extracts (ethanol extract, chloroform, ethyl acetate, n-butanol, aqueous fractions) was determined the TPC by Folin-Ciocalteu reagent, anti-inflammatory proficiency by in vitro protein denaturation and membrane lysis assays.
