Antioxidant and α-glucosidase inhibitory activities of isolated compounds from ipomoea aquatica

Ipomoea aquatica Forsk is a green leafy vegetable that is a rich source of amino acids and vitamins. Antioxidant and α-glucosidase inhibitory activities of the hexane (IAHE) and methanol (IAME) fractions of the vegetable portion of I. aquatica were investigated. The IAME fraction exhibited a strong...
