Two new rearranged taxoids from Taxus wallichiana ZUCC.
Two new rearranged taxane diterpenoids, 5alpha,7beta,10beta,13alpha-tetrahydroxy-2alpha,9alpha,15-triacetoxy-11(15-->1)-abeo-taxa-4(20), 11-diene (1) and 5alpha,9alpha,10beta,13alpha-tetraacetoxy-15-hydroxy-11(15-->1)-abeo-taxa-4(20), 11-diene (2) have been isolated from the barks of Taxus wallichiana. The structures of these compounds have been confirmed by modern spectroscopic techniques.
