Scirpus maritimus L., Carex Paradoxa Willd., sterols, triterpenoids, GC-MS, TLC, CCAbstract
Triterpenes and sterol fractions were isolated from the herb Scirpus maritimus L. and Carex Paradoxa Willd. by typical extraction with petroleum ether. The fraction of sterols was investigated using Gas Chromatography/Mass Spectrometry (GC/MS) techniques. The occurrence of cholesterol, campesterol, stigmasterol, and β-sitosterol 5α-stigmast-7EN-3α-ol has been observed in the Carex paradoxa Willd. Their percentage in the herb has been determined by quantitative analysis. The presence of campesterol, stigmasterol and a mixture of sitosterols in the herb Scirpus maritimus L. was indicated and its percentage in the herb was determined. Thin Layer Chromatography (TLC) was carried out to identify triterpenoids contained in investigated plants. By comparison with the standards of lupeol and β-amyrine the presence of lupeol and an unknown compound in Scirpus maritimus Willd. has been indicated. In the separation of triterpenoids Column Chromatography (CC) was used. Melting point of an unknown compound was marked, but it was unidentified because of lack of appropriate standards.
