In Vitro antioxidant activity of extracts from the leaves of Abies pindrow Royle
Traditionally, the leaves of Abies pindrow Royle are employed as an ayurvedic remedy for fever, hypoglycaemic, respiratory and inflammatory conditions. In this study, dichloromethane, methanol and acetone extracts of A. pindrow leaves were analysed for their phytochemical content and in vitro antioxidant activities. The methanol extract exhibited highest antioxidant activity while acetone extract showed presence of relatively high total phenol and flavonoids contents. The present study provides evidence that extracts of Abies pindrow leaves are a potential source of natural antioxidants and could serve as a base for future drugs.
