Abstract
Medicinal plants have been in use since 5000 years. Oldest known herbal is Pen- t’sao written by emperor Shen-Nung around 3000 years. It contains 365 drugs, one for each day of the year.

(Apocynaceae), commonly known as “Vilayti vakundi” is found all in dry area in India. The study includes preparation of different extracts by successive solvent extraction for detail analysis. Fluorescence analysis of different successive extract and powder were noted under UV light and normal ordinary light, which signifies there characteristics.
