TLDR
The results revealed that the essential oil inhibited the growth of all fungi tested, including the phytopathogens, Botryosphaeria rhodina, Rhizoctonia sp.Abstract:
An investigation of antifungal activity of the essential oil obtained by steam-distillation (1.1% w/w) of the aerial parts of Ocimum gratissimum and of an ethanolic extract from the steam-distillation residue was carried out using the agar diffusion method. The results revealed that the essential oil inhibited the growth of all fungi tested, including the phytopathogens, Botryosphaeria rhodina, Rhizoctonia sp. and two strains of Alternaria sp., while the extract from the residue was inactive. The essential oil was subjected to TLC bioautography used to detect fungitoxic constituents. The compound that showed antifungal activity was isolated and identified as eugenol. GC/MS analysis showed that eugenol was the main constituent of the essential oil studied. The antifungal activity of eugenol was evaluated against a species of Alternaria isolated from tomato (A1) and Penicillium chrysogenum. The minimal inhibitory concentrations of eugenol were 0.16 and 0.31 mg/disc for Alternaria sp. (A1) and P. chrysogenum, respectively.read more

Rapid chromatographic technique for preparative separations with moderate resolution
Abstract: (11) Potassium ferricyanide has previously been used to convert w'c-1,2-dicarboxylate groups to double bonds. See, for example, L. F. Fieser and M. J. Haddadln, J. Am. Chem. Soc., 86, 2392 (1964). The oxidative dldecarboxylation of 1,2-dlcarboxyllc acids is, of course, a well-known process. See Inter alia (a) C. A. Grob, M. Ohta, and A. Weiss, Helv. Chim. Acta, 41, 1911 (1958); and (b) E. N. Cain, R. Vukov, and S. Masamune, J. Chem. Soc. D, 98 (1969).

TL;DR: Chromatography permits not only the detection of fungitoxic substances per se, but also makes the study of the conversion reactions and of decomposition of such compounds possible.
