Popis:	Crystalline taraxasterol and its acetate were isolated for the first time from Onopordum acanthium. Two-dimensional COSY, HSQC, and HMBC NMR experimentswere carried out forcomplete assignment of signals in the PMR and 13C NMR. Chemical shifts of stereochemically important methyl C atoms C-28 and C-29 were measured.
