1) Antifungal activity of decanoylacetaldehyde, isolated from Houttuynia cordata Thunb., was tested. Its maximum dilution was found to be 1:40, 000 against Aspergillus niger.
2) Decanoylacetaldehyde was found to have the strongest antifungal activity among the various acylacetaldehydes tested, possessing acyl group other than decanoyl.
3) In the Claisen condensation of methyl alkyl ketone and ethyl formate, methyl radical was found to have been attacked by ethyl formate when the alkyl radical possessed odd number of carbon atoms.
