Objective: To standardise the protocol for rapid callogenesis in Mussaenda frondosa L. using leaf explants. Qualitative and quantitative phytochemical analysis of leaf, stem and callus cultures.Methods: The leaf explants were inoculated onto MS medium supplemented with varying concentrations of growth regulators such as 2, 4 - D, NAA, BAP, Kn for the induction of callus. Qualitative and quantitative analysis of total phenol, flavonoids and alkaloids contents of leaf, stem and callus were tested by standard methods. The antioxidant activities were investigated using DPPH radical scavenging method and reducing power assay. The anti - inflammatory activity was evaluated by membrane stabilizing activity.Results: Pale green, healthy, friable and fast growing callus was obtained on the medium enriched with NAA (2mg/l) + Kn (4mg/l). Quantitative determination showed the highest concentration of total phenolics in the methanolic extract of in vitro grown callus (10 ± 1.1 mg of GA/g of extract), flavonoids in methanolic stem extract (137±1.6 mg of Quercitin/g of extract) and alkaloids in methanolic extract of leaf (118.3±1.5 mg/10g of extract). The methanolic leaf extract exhibited highest free radical scavenging activity with IC50 value of 40.6±10.06 μg/ml. The highest membrane stabilizing activity was shown by chloroform extract of the leaf (66.02%).Conclusion: The present preliminary phytochemical and pharmacological analysis may form the basis for drug development in future using callus cultures of M. frondosa.
