title: Chemical compositions and biological activities of the oils from the genus Taxus and factors limiting the regeneration of endangered yews: a review
abstract: The genus <i>Taxus</i> (yews) is the largest genus of the family Taxaceae. It comprises about 24 species with 55 varieties distributed mainly in Asia, Europe, North Africa, and North America. In addition to the taxane diterpenoids and the cancer drug taxol, its species contain many essential oils with actual or potential biological activity. This review covers the chemical constituents as well as biological activities of these oils that have been studied in fourteen countries over 46 years (1975
