Two novel taxane diterpenoids from the needles of Japanese yew, Taxus cuspidata.
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.
