摘　　要：目的通过对苏州市地区5个吴药薄荷药材挥发油成分、含量等相关的研究,为吴门药用植物资源的保护问题提供理论和实验依据。方法采用水蒸汽蒸馏法进行挥发油的提取,运用GC-MS进行化学成分鉴定及含量测定,计算其相似度。结果挥发油含量从0.2%至1.7%(mL/g)不等。除一个样品外,其余相似度都较高。结论苏州地区吴药薄荷其化学成分丰富,薄荷醇含量较高,值得保护与开发。OBJECTIVE To provide theoretical and experimental basis for protection of the Wu medicinal plant resources on the basis of study into the components and contents of volatile oil from mentha species in Suzhou region.Method Volatile oils were extracted with steam distillation,their chemical components were identified and contents were conducted by GC-MS to analyze their similarity.Result The contents of violate oil from five Mentha Haplocalyx samples varied from 0.2% to 1.7 %（mL/g）.9,8,16,12 and 9 compounds in the oils were identified respectively.Besides,the menthol contents were determined with naphthol as the internal standard.The method is rapid,accurate and reproducible.With the help of computer aided similarity evaluation system,four samples were found high similarity.Conclusion：Since there are abundant chemical components and high levels of menthol in Mentha haplocalyx in Suzhou region,it is worthy of protection and development.
