Popis: | Two minor taxane glycosides were isolated for the first time from the needles of Taxus canadensis. Their structures were characterized as 2α,5α-diacetoxy-10β-(6′-O-acetyl-β-d-glucopyranosyl)oxy-14β-[(2′R,3′S)-3′-hydroxy-2′-methylbutanoyl]oxytaxa-4(20),11-diene (1) and 2α,14β-diacetoxy-10β-(β-d-glucopyranosyl)oxytaxa-4(20),11-dien-5β-ol (2) on the basis of 1D and 2D NMR data analysis and confirmed by high-resolution fast atom bombardment mass spectrometry. |
