Abstract

MORALES, GLAUCO; SIERRA, PATRICIA; LOYOLA, LUIS A.  and  BORQUEZ, JORGE. A NEW EREMOPHILANOLIDE FROM SENECIO ATACAMENSIS. Bol. Soc. Chil. Quím. [online]. 2000, vol.45, n.4, pp.601-604. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442000000400012.

The fractionation work of the aerial parts of Senecio atacamensis Phil. afforded, in addition to the already known 6b -hydroxyeremophilenolide, a new sesquiterpene lactone 6b - hydroxy - 8a - methoxyeremophil -1(10),7(11) - dien - 8b,12 olide. The structures were established by spectral data, in particular 2D NMR (DEPT, DQF-COSY, HMQC, HMBC and ROESY).

Keywords : Senecio atacamensis Phil, Asteraceae; sesquiterpenoids; b - hydroxyeremophilenolide; 6b - hydroxy - 8a - methoxyeremophil - 1(10),7(11) - dien - 8b,12 olide.
