Abstract

The rate of growth and production of bioactive substances from Rehmannia glutinosa Liboschitz (Scrophulariaceae) were studied with the variation on the constituents of the culture media. The best growth was observed from MS basal medium containing 3.0 ppm NAA and 2.0 ppm kinetin. Carbohydrates (fructose, glucose and sucrose), phytosterols(${\beta}-sitosterol$, campesterol and stigmasterol) and carotenoid like substances were identified by GC-MS and TLC from the callus mass. However, catalpol was not detected from both solid and cell suspension cultures containing geraniol. Callus cultured Rehmannia glutinosa in the MS basal medium containing 0.1 ppm NAA and 0.1 ppm kinetin become differentiated to root.
