Microsurgery characteristics, antioxidant and α - Glucosidase inhibition activities of Ipomoea pes - caprae
Abstract
Ipomoea pes - caprae is a wild plant grown on beaches in Southeast Asian countries so they are easy to find. Currently, only some parts such as flowers, fruits, seeds, and roots of Ipomoea pes - caprae have been studied to show quite good antioxidant potential. The study aimed to investigate the microsurgical characteristics, chemical composition and some biological activities of Ipomoea pes - caprae extracts. Research results showed that leaf microsurgery has an upper epidermis, thick tissue, libe, wood and lower epidermis. Body microsurgery has epidermis, lamina propria, soft tissue, hard tissue, libe, wood and soft tissue. The main chemical components of Ipomoea pes - caprae are polyphenols, carotenoids, anthraquinones, saponins, tannins, polyuronic compounds. The DPPH free radical scavenging test showed that the antioxidant activity of 50% ethanol extract was the highest with IC50 = 7.95 ± 0.35 µg/mL. The extracts also showed strong α-glucosidase inhibitory activity in which aqueous extract was the strongest with IC50 = 7.92 ± 0.05 µg/mL. However, the 96% ethanol extract had negligible α-glucosidase inhibitory activity.
