Dr. S. Bangajavalli*

ABSTRACT

Saraca asoca (Roxb.) Willde.belongs to the family Fabaceae. It is commonly Asoka tree.Te investigation was carried out to determine the bioactive compounds of bark of Saraca asoca using Perkin-Elmer Gas Chromatography – Mass Spectrometry, while the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology(NIST). GC-MS analysis of ethanolic extract of Saraca asoca bark revealed the existence of sixteen compounds. Among these the major compounds are1,3-Benzenediol, 4-propyl- (30.03%), 2-Hydroxy-5-methylisophthalaldehyde (22.06%), Homovanillic acid (8.60%), Methyl 4-Omethyl- d-arabiopyranoside (7.34%), Methoxyolivetol (6.79%), n-Hexadecanoic acid (6.00%) and the minor compounds are β-Sitosterol (4.04%), 9,12-Octadecenoic acid (Z, Z)- (3.41%), 9-Octadecenoic acid (Z)-, methyl ester (2.45%), Isoquinolin-6,7-diol-1-carboxylic acid, N-acetyl-l-methyl- (0.77%), Butorphanol (0.62%). The results of this study offer a platform of using Saraca asoca bark as herbal alternative for various diseases.
