Phytochemical constituents and antioxidant activity of various fractions of Guazuma tomentosa root heartwood

Renuka Jain, Namita Yadav

Abstract


Guazuma tomentosa is an important medicinal plant. The present investigation deals with GC-MS analysis of pet.ether, dichloromethane and ethyl acetate fractions of root heartwood of  G. tomentosa. In antioxidant activity of these fractions by employing DPPH free radical scavenging effect and FRAP total reduction capability method dichloromethane fraction was most effective exhibiting activity nearly equivalent to that of ascorbic acid (standard) at higher concentration, which could be attributed to the phenolic constituents in this fraction. Results indicated that dichloromethane fraction can be a potential source of natural antioxidant agents.
