Establishment of suspension cell culture of Gymnema sylvestre R.Br.- A threatened anti-diabetic plant


A cell suspension culture was established from leaf explants of wild Gymnema sylvestre plants collected from Muniyankudisai,Tamilnadu, India. Murashige and Skoog medium supplemented with 9.0 μM l-1 of 2, 4- Dichlorophenoxy acetic acid and 2.1 μM l-1Benzyl adenine produced yellow friable callus with green patches.The cells were subcultured conscientiously twelve times to getconsistent growth of the cells in suspension. From the 10thsubculture onwards callus cells acclimatized to grow in suspensionwith aggregation and reached 168.6 g l-1 fw and 5.16 g l-1 dw of cellbiomass.
