Bacterial resistance to antibiotics causes the death rate to increase. In dealing with this problem, studies were carried out, one of which was by utilizing natural medicinal ingredients such as bawang sabrang (Eleutherine palmifolia Merr.) of the Iridaceae family. This study aims to determine the antibacterial activity of the residual fraction of the ethanolic extract of bawang sabrang bulbs (Eleutherine palmifolia Merr.) against gram-positive and gram-negative bacteria and to determine the class of chemical compounds.
The residual fraction of the ethanolic extract of bawang sabrang bulbs had antibacterial activity on all the tested bacteria. The chemical compounds contained in the remaining fraction of the ethanolic extract of bawang sabrang bulbs are alkaloids, flavonoids, glycosides, saponins, anthraquinone glycosides, tannins, triterpenoids, and steroids.
