The present paper deals with the relationship between biological activities of some aliphatic and aromatic acids and their physico-chemical parameters expressing the influence of hydrophobic factors. The test strain in the biotest of growth inhibition was the fungus Fusarium moniliforme CCMF-180 and Penicillium expansum CCMF-576. Significant relationship between antifungal activities of un-ionized form of aliphatic acids and their capacity factors (log k'0) extrapolated to pure water, partition coefficients determined in 1-octanol-water system (log Poct) and the first order of molecular connectivity indices (1χ) were calculated. The ionized form of aliphatic acids were antifungally active too. For benzoic acids significant relationships between antifungal activities and capacity factors of anionic form (log k'ia) were calculated.

Spectroscopic Identification

3-Hydroxy retinal acts as visual chromophore instead of retinal in the eyes of several insect orders. A HPLC separation system of the aldehyde and oxime isomers and their identification by 400 MHz 1H NMR spectroscopy is described.
