IntroductionAbout 2.5-7% of the world's populations diagnosed with leading endocrine disease diabetes mellitus which causes morbidity and mortality (Seghrouchni et al., 2002). By the act of pancreatic -amylase, starch has hydrolyzed and absorbed as glucose in the small intestine by -glucosidases, leads to hyperglycemic condition. Moreover, the use of several approaches, -glucosidase inhibitors is one of the alternative therapeutic approaches. Dietary carbohydrates such as maltose and sucrose absorbed by different types ofglucosidases viz. maltase, sucrase, glucoamylase and isomaltase present in the intestine. Thus, inhibition of these enzymes can definitely decrease the postprandial hyperglycemia and could be a key tactic in the managements of diabetes mellitus (Hirsh et al., 1997).The -glucosidase inhibitors have isolated from natural sources, such as plants, foodstuffs and microbes (Kumar et al., 2011).Coastal medicinal plants also engage in recreation to treat diabetes, particularly where most people have limited resources and do not have access to modern treatment (Ramanathan, 2000). The main interest of studies in to medicinal plants with hypoglycemic effect is to understand the metabolic activities of human intestinal tract. Citrullus colocynthis used for constipation, edema, bacterial infections, cancer and diabetes.The aerial part of C. colocynthis showed antimicrobial and anti-inflammatory, anti-oxidant and local anesthetic effect reported by Gurudeeban et al., (2010). Suaeda monoica, S. maritime and S. nudiflora are traditional medicines for wound healing and hepatitis. The aerial part of this family plant has triterpenoids, sterols which have antiviral activity (Bandaranayake, 2002
AbstractNumerous metabolic disorders and diseases associated with the glucosidase enzyme activity. Therefore, in the present study we evaluated alpha glucosidase inhibitory effect of coastal medicinal plants on Saccharomyces cerevisiae -glucosidase to control postprandial hyperglycemia. The n-hexane extracts of study plants screened for -glucosidase inhibitory activity using yeast glucosidase. The enzyme kinetics studied Line weaver burk plot method. Among the ten plants Citrullus colocynthis, Aegle marmelos and Ipomoea pes-caprae exhibited potent -glucosidase inhibitory activity, 85.9 ± 0.1, 72.2 ± 0.3 and 67.9 ± 0.1 respectively. From the enzyme kinetics assay potent plants contain uncompetitive inhibitors of alpha glucosidase. C. colocynthis, A. marmelos and Ipomoea pes-caprae have potential alphaglucosidase inhibitors that can exploited for its used to treat diabetes.
