| Abstract: | Experiments were conducted employing saturated C4, C6, C8, C9, C10, C12 and C18 fatty acids, their methyl esters, C8 fatty alcohol, C8, C10 and C12 mono-, di- and triglycerides and C18 mono- and triglycerides on the inhibitory activity against growth of the Avena coleoptiles. The C8, C9 and C10 fatty acids, and the methyl ester of C10 had strong activity which gradually reduced with either increased or decreased carbon chain length. The C10 monoglyceride also exhibited strong activity whereas no effect was found in other glycerides.The C8 fatty alcohol was more active than the C8 methyl ester. The acyl location of the C10 monoglyceride had no effect on the high activity. Concentration of the C10 monoglyceride corresponding to 50% inhibition of the control was 2.3 × 10−4M. |
