Penapisan Fitokimia, Kadar Kurkuminoid dan Aktivitas Antibakteri Temu Hitam (Curcuma aeruginosa (Christm) Roscoe.), Temu Putih (Curcuma zedoaria Roxb.) dan Temulawak (Curcuma xanthorrhiza Roxb.)

The content of secondary metabolites in the rhizome Curcuma genus such as Black turmeric (Curcuma aeruginosa Roxb.), White zedoaria (Christm.) Roscoe) and Java xanthorrhiza Roxb.) play a role various pharmacological activities. One them is curcuminoid compounds which have been proved to antibacterial activity. This study aims screen metabolite compounds, determine verify activity extracts Roxb.). Extraction was carried out by maceration method using 95% ethanol solvent. Phytochemical screening tested for alkaloid, polyphenols, flavonoids, quinones, tannins, saponins, steroids/ triterpenoids compounds. Determination UV-Vis Spectrophotometry method. test microdilution against Staphylococcus aureus, epidermidis, Propionibacterium acne bacteria. results phytochemical showed that three contained polyphenols flavonoids. Quinone are only extract turmeric. Saponin were detected extracts. Meanwhile, steroid/ triterpenoid determination on had highest curcuminoids (16.07 ± 0.023 mg CE/g extract). strongest samples shown with minimum inhibitory concentration (MIC) value 64 mg/mL aureus bacteria; 256 epidermidis 32 These indicate more active
