以总峰面积、总峰面积与峰数比值、峰数及主要挥发物质峰面积为评价指标,研究了以DVB/CAR/PDMS为萃取头的固相微萃取条件对茶油挥发性成分萃取效果的影响.结果显示:当样品量为1.00 g(15 mL品瓶),搅拌速度为100 r/min,萃取温度为40℃,吸附时间为25 min,解析温度和时间为260℃和3 min时,提取到的挥发物数量较多,重现性好,主要挥发物质的萃取效果较好.

Volatile extraction of camellia oil （Camellia oleifera Abel） by headspace solid phase micro- extraction - gas chromatography （HS- SPME - GC） using 50/30 μm DVB/CAR/PDMS fiber are presented. Parameters such as total peak area, ratio of total peak area to number of peaks, peak number and peak area of main volatiles were used for optimization of extraction variables. Extraction conditions that give good total recovery and diversity of compounds from camellia oil headspace are found as follows： 1g oil sample in 15 mL vessel, stirring at 100 r/min, ex...
