According to WHO (world health organization) 80% people around the globe use herbal medicines for primary health care. (1) As per WHO around 21,000 species have the potential of medicinal value. The morphological and microscopic identifications are utilized to determine the authenticity of herbal medicines and the physical and chemical characters are used to evaluate the quality of herbs in the existing quality standards.(2,3,4)
The present study having an aim of investigation of the physico-chemical & preliminary phytochemical screening of four extract that is, ethanolic & aqueous extracts of stem & both these extracts of H. indicus leaves. Moreover, activity also did on four extracts of L. camara leaves & flowers by using ethanolic & aqueous extracts of both individual parts of plant. For solvents ethanol & water has been used.
The physicochemical parameters of powders were determined wis-to-wis extractive value, loss on drying, foreign matter & moisture content. Moreover, micromeretic parameters such as angle of repose, bulk density & tapped density were also evaluated.
The presence of alkaloids, carbohydrates, glycosides, steroids, flavonoids, tannins were found in both stem & leaves extracts although proteins, amino acids & terpenoids were found only in stem extracts of H. indicus
In L. camara presence of carbohydrates & flavonoids were found in both stem & leaves extracts although glycosides, fixed oils, saponins & terpenoids were also found in extracts.
These studies provided referential informationâ€™s in regard to the identification parameters assumed significant in the way of acceptability of herbal drugs in present scenario.
