Abstract: Alstonia scholaris (L.) R.Br. (Apocynaceae), called satiyana in Assamese, is an evergreen tropical tree native to the Indian sub-continent and South East Asia. A. scholaris has a rough grayish bark and a milky sap rich in poisonous alkaloids. The tree is traditionally used by many ethnic groups of North-East India and elsewhere as a remedy for various ailments. Scientific standardization and pharmaco-botanical parameters for the trunk bark is limited; hence this study, which attempts to both analyze the phytochemical composition and establish a physicochemical standard. This information will be helpful in controlling quality parameters for the development of drugs.
