Isolation and Characterization of Octadecanoic Acid from The Ethyl Acetate Root Extract of Trigonella foneum graecum L. by Using Hydroponics Method

Abstract

The octadecanoic acid (OA), methyl ester was isolated and characterized from root of fenugreek (T. foenumgraecum) using ethyl acetate (EAC) in hydroponics method. The OA was characterized by TLC & HPTLC and purified by HPLC. The structure and molecular weight (298) of OA was confirmed by GC-MS. The Rf value of sample (peak 4) was matched with standard. OA has strong anti-bacterial activity in B. subitlis and P. aeruginousa, where as weak activity in S. aureus and E. coli. Among the tested concentration of in vitro anti-oxidant activity of OA was maximum in 40µl and minimum in 20µl.
