title: Two novel taxane diterpenoids from the needles of Japanese yew, Taxus cuspidata.
abstract: Two novel taxane diterpenoids were isolated from the needles of Japanese yew, Taxus cuspidata, and their structures were determined to be lbeta-hydroxy-7beta-acetoxytaxinine (1) and lbeta,7beta-dihydroxytaxinine (2) on the basis of spectral analyses including 2D-NMR studies.
