GC-MS Analysis of Bio-active Compounds in Ethanol Extract of Putranjiva roxburghii Wall. Fruit Peel

Introduction: Putranjiva roxburghii Wall. has long been used in folkloric medicine for treating arthralgia, fever, hemorrhoids, muscle pain and rheumatism. But no reports were found regarding phytochemical constituents in P. roxburghii fruit peel. Therefore, this study was designed to analyze extract of P. roxburghii fruit peel (PRFP). Methods: Gas chromatography-mass spectrometry (GC-MS) analysis of the ethanol extract of PRFP was carried out by using a GC-MS equipment. Results: The GC-MS analysis has revealed the existence of different phytochemical compounds in the ethanolic extract of PRFP. The major compounds in PRFP extract are Cyclohexanol, 5-methyl-2-(1-methylethenyl)- (4.56%), 6-Octen-1-ol, 3,7-dimethyl- (41.07%), Geraniol (2.45%), (1R,2S,5R)-2-(2-Hydroxy-2-propanyl)-5-methylcyclohexanol (14.09%), 2,6-Octadiene, 2,6-dimethyl- (7.04%), p-Menthane-3,8-diol, cis-1,3,trans-1,4- (3.39%), 2,6-Octadien- 1-ol, 3,7-dimethyl-, acetate (6.69%) and 13-Docosenamide, (Z)- (2.83%). A total of 25 compounds identified representing 99.98% of total ethanolic extract. Conclusion: Overall finding suggests that PRFP contain various phytocomponents and is recommended as an important source of pharmaceutical ingredients.
