BIOACTIVE COMPOUNDS OF PILIOSTIGMA THONNINGII ESSENTIAL OIL DETECTED BY THE GAS CHROMATOGRAPHY-MASS SPECTROMETRY

Abstract

This study aimed to investigate the bioactive compounds present in Piliostigma thonningii essential oil (PEO) using the gas chromatography. Essential oil was extracted using the steam distillation method. . A total of about 32 active compound were detected including their percentage area and mass peaks. The active compounds include; Azulene, beta myrcene, beta limonene, cis- linaloxide, alpha cymene, beta ocimene, trans beta ocimene, 4-methylpropiohenone, 1,3 dimethyl-4-Isoprophylbenzene, dodecane, tridecane, 2,3-dimethylnephthalene, 1,8-dimethylnepthalene, alpha thujene, beta pinene, terpinen-4-ol, alpha terpineol, gamma terpineol, alpha cubebene, alpha yiangene, alpha selinene, chrysathenine, alpha allyltoluene, borneol, hexenyl acetate, camhene, n-nonanol, trans-pinocarveol, cis pinocarveol, Fenchol and alpha muurolene. However, the major bioactive compound are beta pinene (25.02%), beta limonene (12.85%) and alpha muurolene (9.63%).
