国产野生薄荷挥发油化学组分变异及其化学型

采用气－质联用的方法，对国产野生薄荷（ＭｅｎｔｈａｈａｐｌｏｃａｌｙｘＢｒｉｑ．）居群的挥发油成分进行了分析，２２个样品可归纳为６个化学型：（１）薄荷酮－胡薄荷酮型（ｍｅｎｔｈｏｎｅ－ｐｕｌｅｇｏｎｅｔｙｐｅ）；（２）胡椒酮型（ｐｉｐｅｒｉｔｏｎｅｔｙｐｅ）；（３）氧化胡椒酮－氧化胡椒烯酮型（ｐｉｐｅｒｉｔｏｎｅｏｘｉｄｅ－ｐｉｐｅｒｉｔｅｎｏｎｅｏｘｉｄｅｔｙｐｅ）；（４）芳樟醇－氧化胡椒酮型（ｌｉｎａｌｏｏｌ－ｐｉｐｅｒｉｔｏｎｅｏｘｉｄｅｔｙｐｅ）；（５）香芹酮型（ｃａｒｖｏｎｅｔｙｐｅ）；（６）薄荷醇－乙酸薄荷酯型（ｍｅｎｔｈｏｌ－ｍｅｎｔｈｙｌａｃｅｔａｔｅｔｙｐｅ）。结合地理分布和薄荷属单萜类成分生物合成途径，对上述主要类型进行了讨论。

The variation and chemotypes of the essential oil components in wild Mentha haplocalyx Briq. in China

The essential oils from twenty two population samples of Mentha haplocalyx Briq. in China were investigated by means of GC MS. Six chemotypes have been found, which are characterized by the main components: (1) menthone pulegone; (2) piperitone; (3) piperitone oxide piperitentone oxide; (4) linalool piperitone oxide; (5) carvone; (6) menthol menthyl acetate. The chemical variability of monoterpenes in Mentha haplocalyx are discussed through geographic distribution, genetics and biosynthetic pathways.
