Abstract

The present study was designed to characterize the physicochemical properties, fatty acids and essential oils profile of Gladiolus psittacinus bulb. Physicochemical analyses were carried out following standard methods. Fatty acid compositions and essential oils were analysed by GC/MS. The saponification and Iodine values obtained were 165.50 mgKOH/g and 42.20 mg/g respectively. 1,8 Cineole (46.05%) dominated the essential oils, while fatty acids such as linoleic acid associated with lowering of fasting blood sugar was present in high concentration. Phosphatidylcholine 23.35 mg/100g was the most dominant phospholipid, while sitosterol 20.03 mg/100g was the highest occurring phytosterol in Gladiolus psittacinus bulb oil. Due to the presence of high concentration of essential fatty acids, essential oils, phytosterols and phospholipids in Gladiolus psittacinus bulb oil, it may be recommended as an important part of human diet, a potential medicinal food whose addition to diet will promote human well-being in the management and treatment of lipids related disorders such as atherosclerosis and cardiovascular diseases.
