Evaluation of antibacterial activity of sesquiterpene Ar- Turmerone from Curcuma soloensis Val. rhizomes

Abstract

Curcuma soloensis Val. is a family plant Zingiberaceae and is known as "temu glenyeh". This plant has potential as a medicinal plant but has not been widely reported about its bioactivities. One of them was antibacterial activity. Therefore, the aim of this study was to evaluate the antibacterial activity of ar-turmerone, a sesquiterpenoid which was successfully isolated from Curcuma soloensis Val. rizhomes. Antibacterial test was carried out by using disc diffusion method and evaluated against four bacteria namely Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Klebsiella pneumonia ATCC 13883, and Pseudomonas aeruginosa ATCC 27853. The result showed that ar-turmerone was not active against all of these bacteria.
