Abstract

The present study was carried out for the identification of phytochemicals present in the roots ofAporosa lindleyana and also to evaluate the total phenol, total flavonoids and antioxidant activity. Total phenol was carried out by Folin Ciocalteu method and the phenolic content was 31.20 mg/100 g of gallic acid equivalent (GE) and the flavonoid content was 203.10±0.9. Antioxidant activity was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the roots of A. lindleyana showed 19.91 mg/100 g of ascorbic acid equivalent antioxidant capacity (AEAC). The gas chromatography-mass spectrophotometer (GC-MS) study was also carried out and it showed the presence of phytochemicals like 1,2-benzenedicarboxylic acid, diphenyl ester (RT: 11.97), pthalic acid, bis (7 methylocytyl) ester (RT: 20.86) and squalene (RT: 24.70).
