Gymnema sylvestre is a natural source of gymnemic acids—a group of closely related triterpenoid saponins used in the treatment of diabetes. The present study is aimed at enhancing gymnemic acid production in G. sylvestre cell suspension cultures using the signaling molecules—methyl jasmonate and salicylic acid. Methyl jasmonate yielded the maximum gymnemic(More)
Enhancement of secondary metabolite accumulation in cultured plant cells through biotic and abiotic elicitation has been recognised as an important biotechnological strategy. Gymnema sylvestre is a rich source of triterpenoid saponins—gymnemic acids used mainly in the treatment of diabetes I and II. The cell suspension cultures initiated from the leaves and(More)
Elicitation is one of the few strategies that find commercial application in the enhancement of secondary metabolite production from plants as well as cell culture systems. Due to their immense medicinal value, production of saponins in suspension cultures has been attempted by many researchers. Gymnema sylvestre is a rich source of gymnemic acids(More)
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(More)
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 ± 0.57 shoots) on MS media supplemented with zeatin at a concentration of 2 mg/l. The callus cultures of A. galanga were initiated from the rhizome explants on MS media(More)
Abutilon indicum exploited for its immense value has been propagated successfully through multiple shoot induction and somatic embryogenesis. Direct regeneration (8.20 ± 0.83 shoots) was achieved from nodal explants using 0.5 mg/l kinetin (Kn) in MS media. The basal callus from nodal explants turned embryogenic on subsequent introduction of 0.2 mg/l TDZ(More)
