Phytochemical and Ethnobotanical Evaluation of Garlic Bulb (Allium sativum L.)
Allium sativum L. bulb has been shown to be nutritionally and medicinally useful. Consequently, the phytochemical constituents and ethnobotanical properties of the bulb were investigated in five localities in Nigeria where many people use the bulb for different purposes. Phytochemical analysis revealed the presence of carbohydrates, glycosides and proteins in high concentrations. Alkaloids, saponins, reducing sugars, oils and steroids were detected in moderate amounts while flavonoids and acidic compounds were present in low concentrations. The bulb extract was however devoid of tannins, resins and terpenoids. The ethnobotanical survey showed that the garlic bulb is widely used for nutritional and therapeutic purposes in Nigeria and other parts of the world.
