摘要

A pair of taxoids were isolated from the needles of Taxus canadensis, which were identified as 2,10-diacetyl-5(Z)-cinnamoylphototaxicin II (1), a new taxoid, and 2,10-diacetyl-5(E)-cinnamoylphototaxicin II (2), a known one, by spectroscopic methods including (1)H, (13)C NMR, HSQC, HMBC, NOESY, and mass spectra.
