文档介绍：1 牡荆叶茎和花挥发油成分分析作者:黄琼, 林翠梧, 黄克建, 陈丽芬, 潘智文【摘要】目的分析牡荆花、叶、茎的挥发油化学成分。方法采用水蒸气蒸馏法提取,运用毛细管气相色谱- 质谱联用法结合计算机检索, 对牡荆花、叶、茎的挥发油化学成分分别进行分析和鉴定, 用面积归一化法测定各化合物在挥发油中的相对含量。结果共鉴定出 85 个不同化合物,其中叶得 50 种化合物,茎得 51 种化合物,花得 28 种化合物。结论 3 种挥发油的主要成分不完全相同。【关键词】牡荆; 挥发油; 气相色谱拟质谱 Abstract : ObjectiveTo analyze the position of the essential oil in the Vitex negundo ( .)Hand 拟 ponents of essential oil in leaves, stems and flowers of Vitex negundo ( .)Hand 拟 Mazz were separated and identified by GC 拟 MS. The amounts of ponents of 2 the essential oil were determined by area normalization. Results85 pounds measured by steam 拟 stilling were identified in total, in which pounds were identified from leaves,pounds were identified from stems, and pounds were identified from principle constituents of the three essential oils are pletely the same. Key words : Vitex negundo ( .)Hand. 拟 Mazz ; Essential oil ; GC 拟 MS 牡荆 Vitex negundo . cannabifolia ( .)Hand. 拟 Mazz , 马鞭草科牡荆属植物, 别名铺香、午时草、土柴胡、蚊子柴、山京木、土常山、野牛膝、布惊草[1], 为落叶灌木或小乔木, 生于向阳山坡、路旁、草丛及灌木丛中, 广布于长江流域及南部各省区[2], 是一种生长速度快、萌蘖力强的可再生植物, 资源丰富。牡荆是传统的药用植物, 它的不同部位的药效也不尽相同,如牡荆茎可治感冒、疮肿、牙痛;牡荆子可祛风、治咳嗽、哮喘;牡荆叶可除湿、杀虫、治痢疾、脚气;牡荆根可治疟疾、关节风湿痛等[ 1]。牡荆叶中含有丰富的挥发油,它具有明显的祛痰、镇咳、平喘的作用,是治疗慢性气管炎的有效药物, 由它制成的 3 牡荆油胶丸已被载入《中国药典》[3] 。牡荆挥发油化学成分的研究曾有过报道[ 4~6] ,但主要是提取牡荆叶中的挥发油, 并且分离鉴定出的组分不多
