Antioxidant and Cytotoxic Activity of Cinnamtanin B1 - an Overexpressed Compound of Pteris vittata L.
Under Heavy Metal Stress
Cinnamtannin B1 is a naturally occuring A-type proanthocyanidin comprised of three monomeric units of flavan-3-ol ((−) epicatechin) (epicatechin-(4β→8,2β→O→7)-epicatechin-(4α→8)-epicatechin) that was for the first time isolated from the roots of Pteris vittata L. growing in Thai Nguyen province. The UHPLC - DAD analysis showed that cinnamtannin B1 is one of overexpressed compounds in this hyperaccumulator under heavy metal stress. This compound was evaluated for its antioxidant on DPPH scavenging capacity and cytotoxic activity against human pancreatic carcinoma (PANC-1) cell line with the IC50 value of 75.7 µM and 62.3 µM, respectively.
Keywords: Cinnamtannin B1, Pteris vittata, DPPH, PANC-1.
