· Plants encounter various abiotic stresses due to their sessile nature which include heavy metals, salt, drought, nutrient deficiency, light intensity, pesticide contamination, as well as extreme temperatures. These stresses impose major constraints limiting crop production and food security worldwide. Abiotic stresses primarily reduce the photosynthetic efficiency of plants, due to their ...
· 1. Introduction There are many reports on the antidiabetic properties of plant matters and galenical components. Polysaccharides are well known as active components. Panaxan A from carrot, aconitan A from Aconiti tuber, and gonaderan B & C from Ganogerma incidum have been reported (Konno et al., 1985, Takahashi et al., 1985, Hikino et al., 1989, Tomoda et al., 1990).
