利用水蒸气蒸馏法制备莲雾花挥发性成分,并结合GC-MS法进行分离和鉴定,用面积归一化法确定相对质量百分含量。采用气相色谱-质谱共分离出61个色谱峰,确定出57个化合物。莲雾花挥发性主要成分为香橙烯(16.6%)、石竹烯(10.2%)、β-榄香烯(10.0%)、4a,8-二甲基-2-异丙烯基-1,2,3,4,4a,5,6,7-八氢萘(5.87%)、α-芹子烯(4.94%)、α-蒎烯(4.65%)等。莲雾花挥发性成分丰富,以萜烯类为主,含有多种生物活性成分。 Volatile components were prepared by steam distillation and separated and identified by GC-MS. The relative mass percentage was determined by area normalization. 61 chromatographic peaks were identified by gas chromatography-mass spectrometry, 57 compounds were identified. The main constituents of the volatile constituents of lotus flower are orange (16.6%), caryophyllene (10.2%), β-elemene (10.0%), 4a, 8-dimethyl-2-isopropenyl- , 3,4,4a, 5,6,7-octahydronaphthalene (5.87%), α-senesene (4.94%), α-pinene (4.65%) and the like. Lotus flower volatile volatile ingredients, mainly terpenes, contains a variety of bioactive ingredients.
