Antimicrobial Activity of Pecut Kuda Leaf Extract (Stachytarpheta jamaicensis (L. Vahl) against Mycobacterium smegmatis

Mycobacterium smegmatis infrequently causes infection, but it is easy to be pathogenic in immunosuppressed patients. Many reported that M. resistance several antibiotics became an impetus for searching new antimicrobials. Therefore, this study aims prove the effect of Pecut Kuda leaf extract (Stachytarpheta jamaicensis (L.) Vahl) on growth mc2 155. This research experimental with a post-test control group design. The susceptibility test was carried out using two-fold microdilution method and resazurin staining. concentration ethanol prepared range 10000.0 – 625.0 µg/ml. Phytochemical analysis content saponins, tannins, flavonoids, alkaloids also extract. can inhibit minimum inhibitory (MIC) 5000 µg/ml (very weak activity) because, at highest 10000 µg/ml, still cannot killed. Furthermore, contains which are known have antibacterial activity. However, further evaluation needed maximize activity extract, example, by fractionating
