Abstract
Methanol extract of Pterocarpus santalinus (leaves) was evaluated for HPTLC finger print, phytochemical analysis and antioxidant activity. Preliminary phytochemical screening (HPTLC fingerprint) revealed the presence of terpenoids, steroids, flavonoids and carbohydrates. DPPH assay was used to determine the antioxidant property. The methanol extract of Pterocarpus santalinus showed significant DPPH radical inhibition (83.4% at 25 mg/ml concentration). The study reveals the potency of Pterocarpus santalinus as antioxidant source. Keywords: antioxidant, DPPH assay, Pterocarpus santalinus, secondary metabolites
Highlights
Healthy, disease free mature leaves of Pterocarpus santalinus were collected from Chittor, Andrapradesh, India
Literature study showed other biological activity but antioxidant activity of this plant, has not been reported. Based on this we have worked on the leaves of Pterocarpus santalinus to find out antioxidant activity, phytochemical analysis and HPTLC finger print
The free radical scavenging activity of the leaf extract and standard reference compound was analyzed by the DPPH assay as described by Sanchez-Moreno et al (1998) with minor modification
Summary
Disease free mature leaves of Pterocarpus santalinus were collected from Chittor, Andrapradesh, India. Free radical scavenging activity and HPTLC finger print of Pterocarpus santalinus L. 2 Jaya College of Engineering, Department of Chemistry, Chennai, India Abstract: Methanol extract of Pterocarpus santalinus (leaves) was evaluated for HPTLC finger print, phytochemical analysis and antioxidant activity.
