GC-MS Analysis of Phytocomponents in Pleiospermium alatum (Wall. ex Wight & Arn.) Swingle, (Rutaceae)

Abstract

Pleiospermium alatum (Wall. ex Wight & Arn.) Swingle is one of the medicinally important plants belonging to the family Rutaceae, commonly known as Malai Naarthai. The present study deals with the GC-MS analysis of ethanol extract of the above mentioned plant. Thirteen phytochemical constituents from leaf and eleven phytochemical constituents from bark have been identified by comparing the chromatogram, peak value of the unknown compound with entries in NIST database. The prevalent compounds viz., Squalene (13.57%), Lupeol (8.81%), 9,12-Octadecadienoic acid (Z,Z)- (8.36%), n-Hexadecanoic acid (6.11%), ethyl ester, Phytol (5.13%) and Hexadecanoic acid (0.93%) are found in leaf. In bark the prevalent phytochemical constituents are 9,12-Octadecadienoic acid (Z,Z)- (18.81%), All-trans-Squalene (17.55%), n-Hexadecanoic acid (12.61%),Oleic acid (5.88%) and 9-Hexadecanoic acid (2.15%) in bark. These results indicate the ethanol extract of leaf and stem bark of P. alatum possess potent antioxidant, anti-inflammatory, anticancer, antitumour, antiarthritic, cancer preventive, antibacterial effects so that it can be recommended as a plant of phytopharmaceutical importance.
