A Quantitative and Qualitative Study of Fatty Acids in Ziziphus Species in Iran
Abstract
Background and Aim: The genus Ziziphus belongs to the Rhamnaceae family with 70 species of trees in the world. There are three native species of this genus in Iran. The fruit of these trees is edible and has medicinal value. Materials and Methods: Ziziphus samples were gathered from natural habitats in Iran. We used cold methylation and gas chromatography to extract and identify of fatty acids. Identification of the fatty acids was carried out through the investigation of the curves. The significance of the quantitative results was evaluated using one-way analysis of variance. Results: The study of fatty acids in pulps and seeds of the Ziziphus species showed that Oleic acid was the indicator in the studied species. Differences in the type of fatty acid were observed between the species. Examination of the fatty acids in the Ziziphus seed revealed that oleic acid is the main constituent of this oil and there is a quantitative and qualitative difference in the fat of the species. Conclusion: The fatty acids in seeds are higher than the fatty acids in the fruit pulp and the percentage of unsaturated fatty acids is higher than that of saturated fatty acids. The findings of this study are consistent those of with previous studies.References
