Triterpenes and sterols in the flowers and leaves of Prunus spinosa L. (Rosaceae).
From the flowers of Prunus spinosa L. a mixture of alpha- and beta-amyrine, a mixture of ursolic and oleanolic acids, ursolic acid, a mixture of beta-sitosterol, gamma-sitosterol and stigmasterol and beta-sitosterol 3-O-beta-D-glucopyranoside were isolated. Their structure was determined by spectroscopic methods (GC/MS, IR, 1H and 13C NMR). Chromatographic methods (GC, HPLC, TLC) were employed to determine the presence of the listed compounds in the leaves. Also, the content of beta-sitosterol, ursolic and oleanolic acids in the leaves and flowers of blackthorn was determined by GC/MSD method.
