Isolation and Analysis of Essential Oils From Bangle (Zingiber purpureum Rosc.) Rhizome

Abstract

This research was conducted to determine the % yield of bangle rhizome essential oil, determine the chemical components of bangle rhizome essential oils, and determine the antibacterial activity of Streptococcus mutans. Isolation of Bangle rhizome essential oils was obtained by a% yield is 0.29%, and the density is 0.94%. The analysis of bangle rhizome essential oils components with GC-MS showed that there were 26 chemical compounds with the highest compounds, namely sabinene at 39.37% and terpineol-4 at 22.87%. Bangle rhizome essential oils has no activity on Streptococcus mutans in a concentration of 0.625%, 1.25%, 2.5%, and 5%. This is indicated by the absence of an inhibition zone on the BAP media. The positive control used was amoxicillin 3%. The negative control used was ethyl acetate p.a. Amoxicillin showed an inhibition zone is 29 mm, a strong inhibition zone against antibacterial compounds. The negative control did not show any activity to Streptococcus mutans, which was indicated by the absence of a clear zone on the test medi
