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.
