dc.description.abstractThe incidences of metabolic disorders such as diabetes mellitus are increasing. One of the therapeutic approaches for this disorder is by reducing the a-glucosidase activity. In the study, the potential of Aglaonema simplex as therapeutic agent especially as glucosidase inhibitor due it polyhydroxylalkaloids was investigated. The in vitro plantlets of A.simplex were cultured in Murashige and Skoog medium for three and four months. The ethanolic extracts obtained were assayed for a-glucosidase inhibition activity. Results showed that stem and root extracts exhibited the high inhibition activity with IC50 4.5 and 3.9 mg/ml respectively at three months culture, 4.1 and 3.2 mg/ml respectively at four months culture. Roots at four months age of culture showed the most effective inhibitor with lowest IC5o value, 3 .2 mg/ml. The Lineweaver-Burk plots revealed that the inhibition activity of leave extracts was uncompetitive type, stems and roots were non-competitive. Km values for stem and root extracts at three and four months were remaining constant, 5.0 mM while Vmax for these parts were changes. Vmax of stem and root extracts were 0.5 and 0.4 mM.min-1 respectively at three months, 0.4 and 0.3 mM.min-1 respectively at four months culture.en_US
