采用顶空固相微萃取和气相色谱—质谱联用技术(HS–SPME–GC–MS)对原产于秦岭不同地点的春兰和蕙兰的鲜花进行了挥发性成分测定。结果表明该地区春兰的花中挥发性成分有40多种,主要成分有3–乙基–2–甲基–1,3–己二烯、(E)–2–辛烯醛和2–壬烯醛等;不同产地的春兰花中主要的挥发性物质构成比较类似,花香类型比较单一,且多数为无香型。而该地区蕙兰的花中挥发性成分多达50种以上,主要成分有(E)–橙花叔醇,二十二碳六烯酸和[1à,2à(Z)]–茉莉酸甲酯等。蕙兰花中挥发性成分中大多为有芳香味的物质,从而使得蕙兰的花具有更浓郁的香味。此外,蕙兰花挥发性成分构成也比春兰复杂,因此比春兰具有更多的花香类型。
The volatile components of flowers from Chunlan and Cymbidium grown in different locations of Qinling Mountains were determined by headspace solid-phase microextraction and gas chromatography-mass spectrometry (HS-SPME-GC-MS). The results showed that there are 40 kinds of volatile components in the flowers of Chunlan, the main components are 3-ethyl-2-methyl-1,3-hexadiene, (E) -2-octenal and 2- Aldehydic, etc .; the main volatile components in the different origins of the spring orchid are quite similar, the types of flowers are relatively single, and most of them are fragrance-free. The flowers of Cymbidium in the region up to 50 kinds of volatile components, the main components are (E) - nerolidol, docosahexaenoic acid and [1à, 2à (Z)] - methyl jasmonate Wait. Most of the volatile components in Cymbidium flower aromatic substances, making Cymbidium flowers have a more rich flavor. In addition, Cymbidium volatile composition is also more complex than Chunlan, so than Chunlan has more floral type.
