Issue Date: | 2005 | Journal: | Phytochemistry | Abstract: | A formylated triterpene named cladocalol has been isolated from the leaves of Eucalyptus cladocalyx, together with ursulolactone acetate, ursolic acid, 3 beta-acetate-12,20(29)-lupadien-28-oic acid, beta-sitosterol and the known flavonoid eucalyptine. Their structures were mainly established by extensive NMR studies (H-1 NMR, C-13 NMR, DEPT, H-1-H-1 COSY, HSQC, HMBC) and mass spectroscopy as well as by X-ray crystallographic analysis. In this paper, we report on the cytotoxic effect induced by cladocalol and its derivatives on the myeloid leukemia cell line HL-60. | URI: | http://hdl.handle.net/10553/50571 | ISSN: | 0031-9422 | DOI: | 10.1016/j.phytochem.2004.12.018 | Source: | Phytochemistry[ISSN 0031-9422],v. 66 (6), p. 627-632 (Enero 2005) |
