چکیده
Many diseases are being spread in the word by micro organisms. This necessitates the development of cost effective and easily available antimicrobial medicines. Plants have generally been source of alkaloids, steroids, terpenoids, carbohydrates, amino acids, vitamins, glycosides and various pigments. The chemical exploitation of varieties of indigenous plants is therefore likely to offer a cost effective treatment for many diseases leading to the development of the nation and welfare of the society. The present communication reports that hydrocarbons, triterpenes and phytosterols present in Alstonia scholaris, are responsible for its medicinal value.
