Trypanocidal Activity of Oil of the Young Leaves of Nepeta cataria L. Obtained by Solvent Extraction
Trypanocidal activity was found in the volatile oil of the Young leaves of Nepeta cataria L. which has been extracted by diethyl ether and analyzed by GC and GC/MS. Four compounds in the oil of N. cataria, representing 97.53% of the oil were identified. The oil was enriched of monoterpenes with α- citral (51.95%) as the major compound. Other main compounds were β- citronellol (9.03%), geraniol ...

The amino acid-catalysed retroaldol condensation previously described for citral has been extended to other α,β-unsaturated aldehydes. In the presence of glycine and an elevated pH, six other α,β-unsaturated aldehydes also underwent retroaldol condensation. Crotonaldehyde, as well as its proposed intermediate, aldol, were converted into acetaldehyde. Hexenal, decenal, methyl crotonaldehyde, far...
