  • Comparison of antidiabetic potential of (+) and (-)-hopeaphenol, a pair of enantiomers isolated from Ampelocissus indica (L.) and Vateria indica Linn., with respect to inhibition of digestive enzymes and induction of glucose uptake in L6 myotubes

    The remarkable a-glucosidase inhibition exhibited by the acetone extract of the rhizome of Ampelocissus indica (L.) and stem bark of Vateria indica Linn. (IC50 23.2 and 1.47 mg mL1) encouraged us to isolate the phytochemicals from these plants. (+) and ()-hopeaphenol (1) and (2) were isolated from A. indica (L.) and V. indica Linn. respectively. Compounds 1 and 2 displayed IC50 values of 21.21 0.987 and 9.47 0.967 mM in an a-glucosidase inhibitory assay. The effect of glucose uptake performed...

  • Enhancing crop diversity leads to farm resilience

    Monocropping of cash crops for generating incomes has displaced mixed farming systems and associated local crop diversity, negatively impacting on food security and climate resilience. Initiatives to produce improved varieties through participatory varietal selection, intercropping trials with pulses and millets and promoting local millet seed production through community seed banks have made farming more resilient and remunerative.

    Home gardens are unique agricultural spaces and one of the oldest production systems; however, they are highly neglected in agricultural development programs. Women’s role, level of participation and responsibilities in home garden management varies across societies. In most cases women play a predominant role (Seeth et al. 1998 ; Talukder et al. 2000 ), whereas in others they perform a supportive role (Hoogerbrugge and Fresco 1993 ); this depends upon the purpose of managing the garden and...
