Volatile components of Pimpinella tragium Vill. from Iran
Volatile components of three parts of Pimpinella tragium Vill. (Umbelliferae family) from Iran were investigated qualitatively and quantitatively for the first time. Essential oils were isolated by hydro-distillation from stems plus leaves, inflorescence and seeds of P. tragium individually. The plant materials were collected from Polour (Northeast of Tehran Province). The yields of the ...

متن کاملOptimizing headspace temperature and time sampling for identification of volatile compounds in ground roasted Arabica coffee.
Equilibration time and temperature were the factors studied to choose the best conditions for analyzing volatiles in roasted ground Arabica coffee by a static headspace sampling extraction method. Three temperatures of equilibration were studied: 60, 80, and 90 degrees C. A larger quantity of volatile compounds was extracted at 90 degrees C than at 80 or 60 degrees C, although the same qualitat...
متن کاملIsolation of Sesaminols as Antioxidative Components from Roasted Sesame Seed Oil
Two antioxidative compounds were isolated from the oil of sesame seeds roasted at 230°C for 15 min and identified as sesaminols (isomers) by MS and NMR analysis. Although sesaminols are present in refined unroasted sesame seed oil, we have demonstrated their presence also in the oil from the roasted sesame seed without refining for the first time. Furthermore, the amounts of sesaminols in sesam...
