Resumen
Sitosterol and the following terpenic compounds have been isolated from the bark of Podocarpus lambertius: 3β-hydroxytotarol, 4β-carboxynortotarol, and macrophyllic and lambertic acids. The leaves yielded sitosterol, stigmastan-3β,5α-diol-6-one, isopimaric acid, phyllocladene, isophyllocladene, 8,9-abieten-15-ol and 17-isophyllocladenol. © 1975. 14 1 243 248 Joly, (1966) Botânica: Introducão à Taxonomia Vegetal, , Editôra Nacional, São Paulo Wenkert, De, McChesney, Watts, (1975) Phytochemistry, p. 15. , in press This compound has been known as 16-carboxytotarol [4-8]. Since this name described a C21 substance with a carboxyl substituent on C(16) of the totarol nucleus, the new name now is introduced in order to remove nomenclature confusionTaylor, (1961) Chem.
