Muell.-Arg. leaves and root.Methods:The in vitro derived rootlets and leaves segments of B.montanum were cut into 0.5-0.7 cm in length and cultured on Murashige and Skoog solid medium supplemented with 3%sucrose,gelled with 0.7%agar and different concentration of 2,4-D either alone or in combinations.The preliminary phytochemical screening was performed by Harborne method.Antibacterial efficacy was performed by well diffusion method and incubated for 24 h at 37℃.Results:The highest percentage of callus formation(leaves segments 86.9±0.56:root segments 78.7±0.51) was obtained on Murashige and Skoog’s basal medium supplemented with 3%sucrose and 2.0 mg/L of 2.4-Dichlorophenoxy acetic acid.The phytochemical study revealed the high quantity presence of steroids,triterpenoids,glycosides,saponins,alkaloids,flavanoids, phenolic compounds,tannins,sugars etc of root and leaves derived calli.The ethanol extract of leaves segment derived calli of B.montanum showed the maximum solubility and antimicrobial activity with the MIC ranged from 100 to 200μL.Conclusions:The preliminary phytochemical study confirmed that the calli mediated tissues showed the higher percentage of metabolite constituents and extraction value compared to the in vivo leaves and roots.The present study observation suggested that a possibility to establish high yielding genotypes by in vitro culture for production of medicinally important bioactive compounds.展开更多
