Phenolics total and antioxidant activity of strawberry (Fragaria chiloensis)

The purpose of this research is to know the total of phenolics and antioxidant activity of Strawberry that grows in the area Alahan Panjang Solok Regency and Padang Panjang city. This research was carried out at the Chemical Laboratory of Agricultural Polytechinc State of Payakumbuh with a long six months time needed. To determine the levels of phenols total used Folin-Ciocalteu methode, and as a standard also to be used galat acid, while on antioxidant activity testing used DPPH free radical absorption methode. The results of research that methanol extract of Strawberries originally from Alahan Panjang have phenol total 180 mg/100 g of fresh sample and higher than Strawberries originally from Padang Panjang with phenol total 139.2 mg/100 g of fresh sample.
