摘要
目的:对3种空白包装材料(聚乙烯铝箔复合膜、聚乙烯塑料膜、牛皮凝膜纸)、3种已包装材料及采用3种包装材料包装12月的枸杞子饮片共9个样品中的挥发性有机物进行比较研究。方法:采用顶空气相色谱法对9个样品中的挥发性有机物进行成分分析,用面积归一化法获得各化合物的相对含量。结果:各样品中挥发性有机物主要为氧化萜类、醛酮类及脂肪酸类化合物,其中挥发性溶剂乙醇、丙酮为空白聚乙烯塑料袋所特有,异丙醇、正戊醇为空白牛皮凝膜纸袋所特有,装有枸杞子12月的牛皮凝膜纸袋及聚乙烯塑料袋中均含有苯甲醛。塑料包装材料中常用添加剂抗氧化剂BHT在3种空白包装材料中均含有,BHA仅在空白牛皮凝膜纸袋中含有;糠醛是包装12月枸杞子的主要成分。结论:采用不同包装材料的枸杞子饮片成分组成及其相对含量均不一样,表明包装材料对饮片成分中挥发性有机物的影响较大。
Objective： To compare volatile organic compounds in nine samples including three blank packaging materials （composite membrane of polyethylene and aluminum foil, polyethylene plastic membrane, leather condensate membrane paper） , these three kinds of materials have packaged and Lycium barbarum pieces have packaged for 12 months using these three kinds of packaged materials. Method： Component analysis of volatile organic compounds in these nine samples was determined by head-space gas chromatography, the relative content of each compound was gained by area normalization method. Result： Vvolatile organic compounds in each sample were mainly oxidation terpenoids, aldoketones and fatty acids compounds, among them, blank polyethylene bag peculiarly included volatile dissolvent （ethanol and acetone） ; Isopropyl alcohol and n-pentanol were only being in leather condensate membrane paper; polyethylene bag and leather condensate membrane paper which packaged L. barbarum pieces for 12 months all contained benzaldehyde. Three blank.packaging material all contained BHT which was additive antioxidant usually used in plastic packaging materials, only blank leather condensate membrane bag contained BHA which was additive antioxidant usually used in plastic packaging materials; furfuraldehyde was the main ingredient in L. barbarum which packaged for 12 months. Conclusion： Compositions and relative content of L. barbarum pieces using different packing materials were different, it showed that packaging materials had an important effect on volatile organic compounds in the pieces.
