Studies on physico chemical characteristics and comparative study on extraction yield of Adulasa (Adhatoda vasica) leaf

Abstract

The objective of present investigation is evaluating physico-chemical properties of Adulasa leaves which have many pharmaceutical effects. In the present investigation the physical properties like weight, length, width, shape and size were observed along with the chemical properties like moisture, fat, protein, ash, crude fibre and carbohydrates which found (15.2), (1.75), (6.12), (2.18), (6.5) and (68.5) per cent respectively. The calcium content was found higher and chromium content was lower in adulasa leaves respectively. Comparative study of leaf extraction was carried out to determine the per cent extraction yield by using various solvents in which aqueous have highest extraction yields and petroleum ether have lowest i.e.(30.1) and (5.6) per cent respectively.
