New taxane diterpenoids from the roots of Taiwanese Taxus mairei.
Five new taxane diterpenoids, taxumairols G (1), H (2), I (3), J (4), and L (5) were isolated from extracts of the roots of Taiwanese Taxus mairei (LEMEE & LEVL.) S. Y. Hu. Compounds 1-4 belong to the new 11(15-->1)-abeo-taxene system, having a tetrahydrofuran ring along carbons C-2, C-3, C-4 and C-20. Compounds 3 and 4 contain an isopropenyl group at C-1 while compounds 1 and 2 are attached wi...
متن کاملTaxane Diterpenoids from Taxus baccata L. Growing in Iran
Background: There are eight Taxus species and two hybrids in the world and Taxus baccata L. (European yew) is the single representative in Iran. Until now, a large number of taxoids possessing different skeleton systems, as well as lignans, flavonoids, steroids and sugar derivatives have been isolated from various Taxus species. Taxoids are highly oxygenated diterpenes isolated from different...

متن کاملNew diterpenoids from the aerial parts of Salvia reuterana
The genus Salvia is a valuable origin of structurally diverse terpenoids. In a project directed at structurally interesting bioactive metabolites from Iranian Salvia species, we studied Salvia reuterana. Two new labdane diterpene, 6β,14α-dihydroxy-15-acetoxysclareol (1), and 14α,15- dihydroxy sclareol (2), were isolated from the aerial part of the plant. Their structures were established mainly...
