目的:揭示浙贝母花中挥发性成分的组成和含量,以及不同处理方式对其组分的影响,为浙贝母花的资源开发提供依据。方法:浙贝母花样品经水蒸汽蒸馏得挥发油,并用气相色谱-飞行时间质谱法进行分析,按峰面积归一化法求出挥发性化学成分的相对含量。结果:在分离到的60种组分中,共鉴定出38种挥发性成分,其中,新鲜浙贝母花中主要的挥发性成分为十八烯酸甲酯类物质,而经流化床或阴干处理后,浙贝母花的芳香醛酮类物质增加,尤以流化床干燥后的浙贝母花,其中的香味成分含量变化最为显著。结论:浙贝母花中挥发性成分的组成和含量与其处理方式密切相关,其中流化床干燥处理的方法增加了其香味成分的比例,因此,可以作为浙贝母花产品加工的一种优选方式。
OBJECTIVE: To reveal the composition and content of volatile components in Fritillaria cirrhosae and the effects of different treatment methods on its components, to provide the basis for the exploitation of the resources of Fritillary. Methods: Volatile oil from the samples of Fritillaria ussuriensis was steam distilled, and analyzed by gas chromatography - time of flight mass spectrometry. The relative content of volatile chemical components was calculated by the peak area normalization method. RESULTS: Of the 60 components isolated, 38 volatile components were identified, of which the main volatile component of Fritillaria cirrhosa was the octadecenoic acid methyl ester, After drying, the aromatic aldehydes and ketones of Fritillaria ussuriensis increased, especially the Fritillaria ussuriensis after fluidized bed drying, in which the changes of the content of the fragrance components were the most significant. Conclusion: The composition and content of volatile components in Fritillaria cirrhosae are closely related to the treatment methods. The method of fluidized bed drying increases the proportion of its fragrance components, so it can be used as a preferred the way.
