Quantitative analysis of total phenolic content in Adhatoda vasica Nees extracts.

Abstract

Adhatoda vasica leaves were analyzed for total phenolic contents. This phenolic component is responsible for antioxidant activity. The amount of total phenols were analyzed with the Folin-Ciocalteu reagent. Gallic acid was used as a standard compound and the total phenols were expressed as mg/g gallic acid equivalents (standard curve equation: y = 0.0061x + 0.0396, R= 0.9991). The total phenol varied from 63.95±2.1 to 92.4±0.14 mg/g in the extracts. The maximum phenolic content was found in the aqueous extract (92.4±0.14 mg/g).
