Abstract

Hibiscus sabdariffa L. has been used traditionally in many countries of the world as food, especially as a flavouring agent in food industry. H. Sabdariffa is used for treating heart, nerve, liver disease, high blood pressure, arteriosclerosis, sore throat, cough, hypoglycaemia, laxative, diuretic, kidney stone, scurvy... The aims of this study are evaluation of bioactivities of H. Sabdariffa and the production of transformed hairy root of H. Sabdariffa for pharmaceutical production. In this study, Yen and Duh method showed the reducing power of ethanol the root extract and leaf extract are higher than that of stem. The root extract showed the α-glucosidase inhibitory activity with IC50 at 0.2 mg/mL is higher than those of stem and leaf. These results shows that root has higher bioactivites than stem and leaf. In this study, hairy roots of H. Sabdariffa were successfully induced via Agrobacterium rhizogenes ATCC 15834 in the plant cells. The frequency of hairy root and number of hairy root induction from the wounded sites of leaves are the highest (100% and 12.89 roots). The stable introduction of rolB and rolC genes of A. rhizogenes ATCC 15834 into H. Sabdariffa plants was confirmed by PCR analysis. Besides, the absence of virG gene confirmed hairy roots as bacteria-free. Subsequently, these results demonstrated that H. Sabdariffa, particularly the roots, has great potential as pharmacological values and hairy root production can be used as pharmaceutical sources.
