摘要
综合研究云南丽江玛卡的裂解产物特征。采用裂解-气相色谱-质谱方法对丽江产玛卡根茎进行分析。结果共鉴定出裂解产物4 9个,主要为酚类、酮类、醛类、烯烃、芳烃、萜类、杂环等化合物,其中相对含量最高的是苯酚6.274%,其次是肉豆蔻酸酯异丙酯4.702%,2,3-二氢苯并呋喃4.433%,其余相对含量在1%以上的化合物有25个、0.5%～1%的有19个、0.5%以下有2个,其他主要产物为D-柠檬烯、2,3-二甲基-2-环戊烯-1-酮、苯乙腈、吲哚、萘等。
The chemical composition of Lepidium meyenii.（maca） root samples from Lijiang was analyzed by pyrolysis-GC-MS.Forty-nine pyrolysates were identified,mainly including phenols,ketones,aldehyde,olefins,aromatics,terpenes and heterocyclic and other compounds.Among them,phenol（6.274%）,isopropyl myristate（4.702%） and 2,3-dihydrobenzofuran（4.433%） were the predominant compounds.Meanwhile,25,19 and 2 compounds were determined to have a relative content of more than 1%,more than 0.5% and less than 0.5%,respectively.D-limonene,2,3-dimethyl-2-cyclopenten-1-ketone,benzene acetonitrile,indole and naphthalene were also found.
