Abstract:
This study was conducted in the laboratories of the Faculty of Science and the Higher Institute for Environmental Research at Tishreen University, where the seeds were collected during In 2020, from plants that grow wild in Syria (Lattakia and Al-Haffa regions), to determine the percentage of castor oil extracted using the Soxhlet device, analyze this oil, and determine its components and percentages using Gas chromatography technology combined with GC/MS mass spectrometry. The results of the analysis showed that the percentage of oil was 40% in the sample taken from the first site, and 54% in the sample taken from the second site, and that the oil extracted from the seeds contains (6) fatty acids, which constituted 100% of the total oil in the first site, and it contains (5) Fatty acids, which constituted 100% of the total oil in the second site, as it was found that the ricinoleic compound was the main component of the oil at a rate of 76.04% in the sample from the first site and 73.68% in the sample from the second site. The first site was distinguished by containing linolenic acid, which constituted 0.41% of the total oil. This difference is due to the quality of seeds, geographical origin, climatic conditions, and differences in varieties.
Keywords: Castor oil, Soxhlet, Ricinoleic, Gas chromatography.
