The lipophylic part of the surface exudate mixture obtained from Salvia adenophora Fernald, which previously showed herbicide activity against Papaver rhoeas L. and Avena sativa L. in dose-response studies and growth experiments [2], was considered for the isolation of cyclic metabolites of the polyunsaturated fatty acids. For these compounds antimicrobial, anti-insecticidal, antifungal and phytotoxic activity are reported. Compounds 1 and 2, were obtained from the n-hexane soluble fraction of the exudate material, subjected to flash column chromatography, and then purified by semi-preparative RP-HPLC. The identification was done by UV, IR, 1H- and 13C-NMR, including COSY, HSQC, HMBC, TOCSY experiments, and HR-ESIMS analysis.

Abstract

The lipophylic part of the surface exudate mixture obtained from Salvia adenophora Fernald, which previously showed herbicide activity against Papaver rhoeas L. and Avena sativa L. in dose-response studies and growth experiments [2], was considered for the isolation of cyclic metabolites of the polyunsaturated fatty acids. For these compounds antimicrobial, anti-insecticidal, antifungal and phytotoxic activity are reported. Compounds 1 and 2, were obtained from the n-hexane soluble fraction of the exudate material, subjected to flash column chromatography, and then purified by semi-preparative RP-HPLC. The identification was done by UV, IR, 1H- and 13C-NMR, including COSY, HSQC, HMBC, TOCSY experiments, and HR-ESIMS analysis.
