A solid-phase microextraction (SPME) method is described for the determination of the essential oils, humulene and caryophyllene, in the headspace of female hop cones and male hop lupulin samples. Optimized SPME sampling parameters for the determination of the humulene to caryophyllene (H/C) ratio for female hops (50 mg) and male lupulin (25 mg) samples include a 100 μm poly(dimethylsiloxane) SPME fiber and a 4 h sample exposure period at a temperature of 50 °C. Increasing the temperature to 90… CONTINUE READING
