| 摘 要： | 采用顶空固相微萃取技术对玛咖中挥发性成分进行富集，用气相色谱-质谱联用技术对其化学成分进行分离和鉴定，在云南8 个种植区玛咖样品中共检出挥发性成分69 种，共有的挥发性成分有18 种。这些成分包括酮类12 种、醛类10 种、醇类9 种、酸类7 种、酯类6 种、烯烃类6 种、杂环化合物5 种、腈类4 种、芳香族类4 种、酚类3 种、胺类2 种、硫醚类1 种。含量较高的挥发性成分是异硫氰酸苄酯、苯甲醛、苯乙腈、乙酸、苯甲醇、二甲基硫醚、3-甲氧基-苯甲醛、4-甲氧基苄基异硫氰酸酯。通过统计比较发现了云南8 个不同种植区玛咖挥发性成分存在的差异。 |

| Abstract: | The volatile components of maca from 8 producing regions in Yunnan province were extracted by headspace solid-phase micro-extraction (HS-SPME) and identified by gas chromatography-mass spectrometry (GC-MS). A total of 69 volatile constituents were identified, of which 18 were common to all the tested samples. The identified volatile constituents included 12 ketones, 10 aldehydes, 9 alcohols, 7 acids, 6 esters, 6 alkenes, 5 heterocyclic compounds, 4 nitriles, 4 aromatic compounds, 3 phenols, 2 amines and 1 sulfoether compound. Among these volatile constituents, benzyl isothiocyanates, benzaldehyde, benzyl cyanide, acetic acid, benzyl alcohol, dimethyl sulfide, 3-trimethoxy-benzaldehyde, 3-methoxyphenyl acetonitrile, 4-methoxybenzyl isothiocyanates and N-phenylmethylene-benzenemethanamine were predominant. Comparison by Excel and SPSS suggested that there were some differences in the type and content of volatile components identified from maca samples from 8 producing areas in Yunnan province. |
