The essential oil was obtained by hexan. The sample oil, which was light yellow in color, was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The oil obtained was analyzed by GC-MS and GC/MS. The components of the oil were identified by comparison of their mass spectra to those of a computer library or with authentic compounds and confirmed by comp...
