摘　　要：建立了同时测定化妆品中8种呋哺香豆素类化合物（8－羟基补骨脂素、补骨脂素、异补骨脂素、8－甲氧基补骨脂素、5－甲氧基补骨脂素、三甲沙林、欧前胡素和异欧前胡索）的高效液相色谱分析方法及液相色谱－串联质谱确证斤法。膏霜类、水剂类、香波类、散粉类、唇膏类等不同类型的化妆品样品分别经适宜的提取溶液进行超声提取．提取液以离心处理后，取上清液经微孔滤膜过滤后测定。采用Agilent Zorbax SB－Phenyl色谱柱（250mm×4．6mm，5μm）分离，以甲醇－乙腈－水三元流动相梯度洗脱，流速1．0mL／min，柱温30℃，检测波长250nm。8．羟辏补骨脂素的定量限为0．25mg／kg，补骨脂素、异补骨脂素、8－甲氧基补骨脂素、5－甲氧基补骨脂素、三甲沙林、欧前胡素、异欧前胡素的定量限为0．5mg／kg。在低、中、高3种加标水平下，8种待测组分的平均回收率为85．0％～105．8％，相对标准偏差为0．41％～7．90％。采用本方法在一日内不同时间点（6个时间点，每隔1h测定一次）和不同日期（6d内）测定混合标准溶液，得到8个目标物峰断积的日内精密度均小于1％，日间精密度均小于2％、该疗法准确、简便、快速，适用于不同类型化妆品中8种呋喃香豆素类化合物的测定。A method using high performance liquid chromatography （ HPLC ） and liquid chroma- tography-tandem mass spectrometry （LC-MS/MS） was developed for the simultaneous determi- nation of eight furocoumarines （8-hydroxypsoralen, psoralen, isopsoralen, 8-methoxypsoralen, 5-methoxypsoralen, trioxsalen, imperatorin and isoimperatorin） in cosmetics. The cosmetic samples, including cream, lotion, shampoo, powder and lipstick, were supersonically extrac- ted with appropriate solvents. The extract was centrifuged, and the supernatant was filtered through a membrane, and then separated on an Agilent Zorbax SB-Phenyl chromatographic col- umn （250 mm x 4.6 mm, 5μm） by gradient elution at a flow rate of 1.0 mL/min with metha- nol-acetonitrile-water as mobile phases. The column temperature was set at 30℃. The wave- length of detection was 250 nm. The limits of quantification （LOQs） were 0.25 mg/kg for 8- hydroxypsoralen and 0.5 mg/kg for psoralen, isopsoralen, 8-methoxypsoralen, 5-methoxypsor-alen, trioxsalen, imperatorin and isoimperatorin. The recoveries at three spiked levels were in the range of 85.0% - 105.8% with the relative standard deviations （RSDs） of 0.41% - 7.90%. The intra-day precision （ n = 6） was less than 1%, and the inter-day precision （ n = 6） was less than 2% for the peak areas of the eight furocoumarines in a mixed standard solution. The method is accurate, simple, rapid and suitable for the determination of the eight furocouma- rines in various cosmetic samples.
