Description
Summary:The oils of Pectis elongata were hydrodistilled and analysed by GC and GC–MS. The major constituents identified in the oils of fresh and dried samples of a specimen collected in Pará state, Brazil, were perilla aldehyde (51.7% and 64.6%) and limonene (43.7% and 33.7%), respectively. The main compound found in the oil of a dried sample of another specimen collected in Amapá state, Brazil, was perilla aldehyde (81.9%), followed by its oxidation derivatives, perilla alcohol (5.6%) and perilla acid (4.0%). The higher percentage of perilla aldehyde in the dried samples is due to the loss of limonene during the drying stage. Probably, the plant oxidation process is initiated in the 1‐methyl group of limonene, converting it to perilla alcohol and thence to the other derivatives. Copyright © 2005 John Wiley & Sons, Ltd.
