Gi. Georg et al., A REINVESTIGATION OF THE TAXOL CONTENT OF HIMALAYAN TAXUS-WALLICHIANAZUCC AND A REVISION OF THE STRUCTURE OF BREVIFOLIOL, Bioorganic & medicinal chemistry letters, 3(6), 1993, pp. 1345-1348
When taken at the appropriate time and place, biorenewable leaves of t
he abundant Himalayan yew, Taxus wallichiana Zucc., contain significan
t quantities (0.045-0.130%) of taxol and other useful taxanes includin
g 10-deacetylbaccatin III and brevifoliol. Spectroscopic reexamination
of brevifoliol indicates that its structure must be revised to 11. Th
is makes brevifoliol and recently reported taxchinin A (12) close mole
cular relatives.
