Taxane Ditepenoids from the Needles of Taxus baccata L. Growing in Iran

Chemical examination of the needles and young stems of Taxus baccata L. from Iran, resulted in the isolation of three taxane diterpenoids , two previously reported taxoids, taxupinanane L and taxupinanane G, and a new taxoid, 2,9-deacetyltaxinine J. The structures of these compounds were determined on the basis of spectroscopic data. These three taxoids were not previously encountered in Taxus baccata L. species.
