Evaluation of genetic stability using FRAPD markers as novel method along with antioxidant and anti-diabetic properties of micropropagated Salacia chinensis L.

Salacia chinensis L., a perennial medicinal plant, is well-known for its well-documented anti-diabetic properties. The daily growing demand in pharmaceutical industry is stimulating the conservation and wide-ranging production of the plant using plant tissue culture techniques (micropropagation). In the present study, the plants generated by direct micropropagation from nodal explants were assessed using fluorescently labeled RAPD (FRAPD) primers. Although standard RAPD primer bands in agarose gel showed genetic stability, using FRAPD analysis in genetic DNA sequencer as a novel strategy showed more accurate and reliable method has indicated by the evidence in 5% genetic variation. Antioxidant and anti-diabetic activities of micropropagated plants versus mother plant were examined using DPPH, FRAP, α-amylase, and α-glucosidase assays. The results showed that the micropropagated plants, which are able to produce higher amount of secondary metabolites than the mother plant, possess higher in vitro antioxidant and anti-diabetic properties
