Sterol profile of some medicinal and aromatic plants: Effect of silyl derivatization step

Erman Beyzi [1] , Selma Büyükkılıç Beyzi [2] , Kevser Karaman [3]


In this study, crude oils were extracted using different parts (seed/fruit) of some medicinal and aromatic plants (fenugreek, fennel, coriander, black cumin and anise) and then sterol composition was determined. Two different methods have been used for sample preparation process. In first method, silyl derivatization was applied and in the other method derivatizing agents were not used. It has been determined that the oil ratios were changed between 4.27 - 4.63% in fenugreek, 8.60 - 9.10% in fennel, 9.57 - 10.70% in coriander, 22.77 - 23.50% in black cumin and 11.10 - 11.50% in anise. Five sterol standards (Brassicasterol, Campesterol, Stigmasterol, β-Sitosterol and β-Sitostanol) were used in the study. After preparation step, samples were injected into the Gas Chromatograph device and the analysis was carried out. In both methods, β- sitosterol was the highest component of sterol in oils. It has been determined that lower results were obtained in the method performed with the derivatizing agents. Brassicasterol has been identified only in anise and fennel oils in the method performed without the derivatizing agents, while it has also been found in black cumin oil in other method. According to literature, it was concluded that the derivation process was more compatible.
