| Summary: | Clitoria ternate L. widely found in Asia, Caribbean and South America which usually experiences tropical zones. Nowadays, these plants were widely used as medical plant for health purpose. The aims of this study are to analyzed the chemical compounds of crude flowers extract by phytochemical screening and to evaluated the antibacterial activity by using disc diffusion method. In this study, Clitoria ternatea L. flowers was extracted by using Soxhlet extraction method and ethanol was used as a solvent. From the extraction, the percentage yield of crude extract is 5.14%. The result for phytochemical screening shows that tannins, glycosides and saponin were found in Clitoria ternate L. flowers. The extracted crude extract was tested against two types of bacteria which are B. lichen and E. coli with three different concentrations. The average inhibition zone of Clitoria ternate L. flowers extract for 30 ppm, 20 ppm and 10 ppm against B. lichen are 13.3 ± 0.6 mm, 10.3 ± 1.5 mm and 8.3 ± 0.6 mm, respectively while for E. coli are 10.3 ± 1.5 mm, 8.3 ± 1.5 mm and 8.3 ± 1.2 mm, respectively. Different concentration shows different inhibition zone and 30 ppm shows the highest inhibition zone followed by 20 ppm and 10 ppm of extract. All concentrations of flowers extract showed less effective against both bacteria. |
