Clove (Caryophilli Flos), dried flower-buds of Eugenia caryophyllata, commonly distributed in China. has been used in traditional oriental medicine as vermifuge, antibacterial agent and to treat toothache. The quality evaluation of clove was carried out by means of gas chromatography (GC) using eugenol as marker. GC/MS analysis provided the identification of eugenol separated from the extract of clove. Adequate separation of eugeno1 from commercial clove samples was achieved with a fused-silica 100% dimethylpolysiloxane capillary column (SPB-1. 30 m x 0.53 mm. 0.5 μm film thickness) and operated with temperature programming from 140 ℃ held 1 min. increased at 30 ℃/min to 290 ℃ held 2 min and the carrier gas flow-rate (nitrogen) was 4.3 ml/min on flame ionization detector The method showed a good within-day (35%) and between-day (9.5%) precision according to the acceptance criteria. The concentration of eugenol in the commercial clove samples was ranged from 1.3% to 19.7% and the lowest concentration of eugenol determined for the quality evaluation of commercial clove was 27%. This procedure was successfully applied to the monitering of eugenol in colve.
