10.22376/ijpbs.2019.10.1.p1-12 Volume 1 Issue 4 2010 (October - December) The present work deals with evaluation of anti-tubercular activity of various aldehyde derivatives synthesized by Claisen-Schmidt condensation method. The formation of pyrazole derivatives by reaction with phenyl isothiocyanate was also attempted. The synthesized derivatives were screened for anti-tubercular activity and the compounds. All the Compounds characterized on the basis of their IR, MASS, 1H NMR spectroscopic data analysis.  Vimal I. Patel,Dr. Bhavesh Patel Synthesis,condensation,Pyrazolines,Antimycobacterial. 453-458
