title: A new taxane diterpenoid from Taxus chinensis var. mairei.
abstract: Taxadiene (3), a new taxane diterpenoid with an unusual hydroxy substituting at C-17, and six known compounds including two taxane diterpenoids (1 and 2) and four flavonoids (4-7) were isolated from the whole seedling of the Taxus chinensis var. mairei. Among them, compound 7 was isolated from T. chinensis var. mairei for the first time. Structures of these compounds were elucidated on the basis of spectroscopic data and by comparison with reported literature data.
