ABSTRACT

In this study, Ornithogalum umbellatum L. growning around Edirne has been phytochemically investigated. Choloroform (CHCI,) and CHCI,:C₂Н,OH (2:1) extracts of the plant bulbs were seperated and purificated by using chromatographic methods. The chemical structures of the isolated four compounds from plant were elucidated by using UV, IR, NMR and FAB-Mass spectroscopies. One of them, 1-(2- methyl-undecanyl)-2-(3-methyl-heptyl)-benzenedicarboxlic acid diester, was shown below. In addition, CHCI, and CH,OH raw extract of the bulbs were combined and then was investigated for its antimicrobial activity. The raw extract at test concentrations did not inhibit growth of Bacillus subtilis, it was more effective relatively to gram-positive coccus excluding Enterococcus faecalis. For Enterococcus faecalis and Candida albicans, it was determinated to be the least effective. For gram-negative bacils, it showed that extract was variable effective.
