Gymnema sylvestre is an important medicinal plant that bears bioactive compound namely gymnemic acids. The present work deals with the optimization of a cell suspension culture system of Gymnema sylvestre for the production of biomass and gymnemic acid, which has anti‐diabetic properties. We investigated the effect of inoculum densities (2.5–20.0 g/L), the strength of the Murashige and Skoog (MS) medium (0.25–2.0), carbon source (sucrose, glucose, fructose, maltose), and the concentration of the sucrose (1–8% w/v) to determine their effects on biomass accumulation and production of gymnemic acid. Overall, 10 g/L of inoculum density, full‐strength MS medium supplemented with 2,4‐dichlorophenoxy acetic acid (2.0 mg/L) and Kinetin (0.1 mg/L), and 3% w/v sucrose was found best for the accumulation of biomass and gymnemic acid content (9.95 mg/g dry weight). The results of the current study will be useful for bioprocess and biochemical engineers for large‐scale production of gymnemic acid in cell culture.
