Abstract	Wrightia tinctoria (Roxb.) R.Br. belongs to family Apocynaceae is found in Western Ghats of India and is popular for its fragrant flowers and leaves oil. Extraction of essential oil from flowers was standardized by soxhlet extraction with ehanol. Essential oil extracted from flowers was also subjected to GC-MS analysis. The major components identified by soxhlet method were Phenol, 4-ethyl-2-methoxy (1.75), 3-Pyrimidinecarboxylic acid (1.69), 2, 5, 7-Nonatrien-4-one (0.91), 3-methyl-3-butanoic acid (11.52), 3, 6-Dioxa-2, 7-Disilanone-4,5-dicarboxylic acid (0.84), 2, 2, 7,7-tetra methyl- dimethyl ester (1.05), Diethyl phthalate (0.96). The major components identified in flowers by soxhlet technology were 15-methyl, methyl ester (40.90), Hexadecanoic acid (20.12) and Propanoic acid, 2-mercapto (15.40). The essential oils extracted from Wrightia tinctoria (Roxb.) R.Br. were also subjected to olfactory evaluation.
