Indole alkaloids in clonal propagules of Rauwolfia serpentina benthe ex kurz

Plantlets were succesfully regenerated from shoot cultures of Rauwolfia serpentina initiated from auxillary meristems on medium containing BA (4.44 M) + NAA (0.54 M). Rooting was initiated in White's basal medium supplemented with NAA (0.54 M). Tissue culture derived piants of R. serpentina (RSTC) were similar to normal plants (RS) in their morphological characteristics and chemical consitution. The biomass of the RSTC plants was higher (47.11 gms) than the normal plant (18.23 gms) on a dry weight basis. Five RSTC plants were cloned and the cloned plants were similar in biomass and alkaloid content to the normal plant.Abbreviations BA benzyl adenine - NAA naphthalene acetic acid - MS Murashige and Skoog - TLC thin layer chromatography - HPLC high performance liquid chromatography - F.W. fresh weight - D.W. dry weight - RS normal field grown plant established from stem cuttings - RSTC tissue culture plants established from shoot cultures - R reserpine - Aj ajmalicine - A ajmaline - S serpentine
