Salvia adenophora Fernald [1] is a Mexican species whose aerial part exudate showed herbicide activity against Papaver rhoeas L. and Avena sativa L. in a preliminary test [2]. The surface exudate, obtained by rinsing the plant material with CH2Cl2, was subjected to repeated column chromatography on Sephadex LH-20 and silica gel and to HPLC-MS and MS2 experiments followed by semi-preparative RP-HPLC, yielding a new prostaglandin-like (1). The new compound was identified by IR and NMR analysis, including TOCSY, COSY, HSQC, HMBC experiments, and ESI-TRAP-MS and HR-MS analysis.Bibliografia 1 Epling, C.
