(60j) “Essential Oil Constituents of Petiveria Alliacea L. by Soxhlet Extraction and GC-MS”

Since the end of the last century numerous studies have been carried out to investigating the insecticidal activity of herbs. Since 1949 the Petiveria alliacea L. plant have been recognized as a prospect source of natural insecticide. To explore the possibility of this field a study of the essential oil constituents of this plant was investigated. Petiveria alliacea L. is an herbaceous perennial that grows up to 1 m in height. It is indigenous to the Amazon rainforest and tropical areas of Central and South America, the Caribbean, and Africa. The soxhlet extraction technique was carried out with two different solvents, dichloromethane, CH2Cl2 and methanol, CH3OH using 0.4g of the plant powder. Gas Chromatography coupled to Mass Spectrometry, GC/MS was used to identify the essential oil constituents. The dichloromethane and methanol extract have several common compounds but methanol have more chemical constituents. The essential oil of the methanol extract was three times more than dichloromethane extract. The most abundance compounds is phytol follow by 4-vinyl-2-methoxy-phenol and phytol and hexadecanoic acid in methanol and dichloromethane extracts respectively. Some of the constituents are classify as insecticide, benzenecarboxylic acid, 5,6,7,7a-Tetrahydro-6-hydroxy-4,4,7a-trimethyl-2(4H)-benzofuranone, benzenemethanethiol, 4-vinyl-2-methoxy-phenol and others.
