Abstract

The free radical scavenging activity of Thespesia populnea bark (TPBE) and leaves (TPLE) has been studied using the methanolic extracts. In vitro antioxidant potential of leaves and stem bark were evaluated in three different models viz superoxide radical scavenging activity, lipid peroxide radical scavenging activity and hydroxyl radical scavenging activity. The two methanolic extract were prepared with different concentration from a maximum of 400μg to minimum of 50μg. All extract have different level of antioxidant property. In comparison, the antioxidant scavenging activity in hydroxyl radical was higher, In super oxide radical was moderate and lesser in lipid peroxide radical. These observations confirm that methanolic extract of Thespesia populnea bark and leaf have different polyphenolic constituent and its importance in antioxidant activity.

Abstract

Thespesia populnea is a reputed ever green tree belonging to the family Malvaceae; commonly known as Indian tulip tree. The plant is distributed tropical regions and coastal forest in India. It is well known and all the parts are used in traditional system of medicine. The plant has been used as astringent, antibacterial, hepatoprotective, haemostatic, anti-diarroheal and anti-inflammatory. The scientific parameter is necessary to identify the exact plant material and to find its quality and purity. The present study deals with various pharmacognostical examinations like organoleptic or macroscopical characters, microscopical or anatomical studies, physical evaluation and preliminary phytochemical screening of various successive extracts were carried out and the parameters were reported. These studies indicated the possible information for correct identification and standardization of this plant material.
