A COMPARATIVE PHYTOCHEMICAL ANALYSIS OF CHURNA AND BHAVITA CHURNA OF STEM BARK OF ASOKA – SARACA ASOCA (ROXB.) DE WILDE
Abstract
Bhavana is a process for potentiating or purification of drugs. Bhavana should be done for seven times by completely soaking the churna (powder) in any liquid (swarasa, kashaya etc) for one whole night and then drying the next day under sunlight. This increases the efficacy of the drug and hence the effective dose can be reduced. In the present study, bhavana of churna (powder) of stem bark of Asoka [Saraca asoca (Roxb.) de Wilde] was done in kashaya prepared of stem bark of the drug and bhavita churna was made. The preliminary phytochemical evaluation of churna and bhavita churna of stem bark of Asoka [Saraca asoca (Roxb.) de Wilde] was carried out. On analysing the presence of phytochemical constituents both churna and bhavita churna revealed the presence of alkaloids, flavonoids, saponins, carbohydrates, phenols, steroids and tannins. Bhavita churna showed more extractive and successive solvent extractive values than churna of the drug indicating quantitative enhancement of phytoconstituents which substantiate the fact that process of bhavana help to increase the potency and efficacy of the drug.
Key words: Bhavana, Churna, Bhavita churna, Stem bark, Asoka
