Treatment of Botrytis cinerea with a novel fungicide SSF-109, (dl)-cis-1-(4-chlorophenyl)-2-(1H-1,2,4-triazol-1-yl)cyclo-heptanol (0.45 μg ml-1), gave five 14α-methyl sterols, 24-methylene-24(25)-dihydrolanosterol, 24-methylene-24(25)-dihydrolanosten-3-one, obtusifoliol, obtusifolione, and 14α-methylfecosterol, together with ergosterol and ergosta-5,8,22-trien-3β-ol.SSF-109 was found to inhibit the biosynthesis of ergosterol at the 14α-demethylation step.
Triterpenes issus des latex des euphorbes cactoides marocaines E. resinifera, E. echinus et E. officinarum : isolement, etude comparative par RMN (13)C des quatre classes tetracycliques, eupho-lanostane, elemo-lanostane, lanostane, et nor-31 lanostane

The latex of moroccan Euphorbia : E. resinifera, E. echinus et E. officinarum has been examined for triterpene content.Three tetracyclic triterpenes from E. resinifera and ten penta or tetracyclic triterpenes including 4α-methyl sterols from E. echinus and E. officinarum, have been isolated.The carbon-13 NMR spectra have been recorded and all carbon shifts have been assigned for representatives of the four classes of tetracyclic triterpenes.It has been found that the differences in the 3-C, 9-C, 17-C, 20-C and 21-C chemical shifts for these triterpenes are remarkable, being significant for the characterization of the four classes.
