The chemical compositions of essential oils of some Piper species were determined by capillary GC and capillary GCยฑMS. Elemol (11.5%) constituted the most abundant component of Piper nigrum leaf oil, b-Caryophyllene (13%) was the major constituent of P. attenuatum leaf oil, whereas b-cubebene (10%)

โฆ Synopsis
The constituents of the essential oil of Matricaria decipiens C. Koch (Asteraceae) were investigated by GLC and GCยฑMS. Twenty-seven components, representing 96% of the oil, were characterized. The major components were isomers of matricaria ester with 1,8-cineole. The dierent isomers of matricaria ester were separated by TLC and preparative HPLC. The stereochemistry of the dierent isomers was assigned by NMr spectral data.
