Elicitation of andrographolide in the suspension cultures of Andrographis paniculata.

Andrographis paniculata belonging to the family Acanthaceae produces a group of diterpene lactones, one of which is the pharmaceutically important-andrographolide. It is known to possess various important biological properties like anticancer, anti-HIV, anti-inflammatory, etc. This is the first report on the production of andrographolide in the cell suspension cultures of Andrographis paniculata by 'elicitation'.

Agrobacterium-mediated transformation in Alpinia galanga (Linn.) Willd. for enhanced acetoxychavicol acetate production.

Agrobacterium-mediated transformations ensure elevated amounts of secondary metabolite accumulation with genetic and biosynthetic stability. In the present study, Alpinia galanga rich in bioactive compounds was genetically transformed using different strains of Agrobacterium rhizogenes viz. LBA 9402, A(4), 532, 2364 and PRTGus.

Phytochemical analysis of Gymnema sylvestre and evaluation of its antimicrobial activity.

Gymnema sylvestre (CS 149), known to be a rich source of saponins and other valuable phytochemicals, has been analysed for antimicrobial activity. The chloroform extracts of aerial and root parts of G. sylvestre exhibited higher antimicrobial activity as compared to diethyl ether and acetone.

Direct and indirect organogenesis of Alpinia galanga and the phytochemical analysis.

Alpinia galanga is a rhizomatous herb rich in essential oils and various other significant phytoconstituents. Rapid direct regeneration was obtained from the rhizome explants (15.66 ± 0.
