Antituberculosis activity of extract and fractions of Tinospora Crispa against mycobacterium tuberculosis H37RV using mycobacteria growth indicator tube and agar proportion method

Abstract

Objective: The increasing incidence of multidrug-resistant tuberculosis (TB) has created a need to discover a new anti-TB drug candidates. The aim of this study was to screen extract and fractions of Tinospora crispa for activity against Mycobacterium tuberculosis H37Rv. Methods: The dried and pulverized T. crispa stem was extracted by maceration method using ethanol (96%). The anti-TB activity was carried out using mycobacteria growth indicator tube (MGIT) system and agar proportion method with Lowenstein–Jensen (LJ) medium. Result: The result of this study showed that ethanolic extract and fractions of T. Crispa did not exhibit anti-TB activity in the range of 100–1000 µg/ml with MGIT method, while with agar proportion method, there were M. tuberculosis colonies growth on the LJ containing 1000 µg/ml extract slants. Conclusion: The tested extract and fractions of T. crispa have no anti-TB activity against M. tuberculosis until 1000 µg/ml.
