摘要
比较了12批海南高良姜挥发油的GC-MS指纹图谱,对其中20个特征化合物进行了相似度评价。结果表明,海南省不同地区的高良姜品质相似。与相同生长年份和相同采收期的徐闻产高良姜进行比较,海南不同产地高良姜在挥发油得率及挥发油主要成分上与其无显著差异,而且两地的高良姜GC-MS指纹图谱的相似度为0.956。因此,海南产高良姜可替代徐闻产高良姜用于食品和香料。
The volatile oil extracted from Alpinia officinarum growing in 12 localities of Hainan was analyzed by using GC-MS fingerprinting,and 20 characteristic peaks selected from the GC-MS fingerprints were evaluated in terms of similarity.The results showed that the volatile oil extracted from A.officinarum sampled from different localities in Hainan had similar quality.The yield and main constituents of the volatile oil extracted from A.officinarum in different localities of Hainan were compared with those in Xuwen,Guangdong at similar ages and harvest time,and no significant difference was observed.Moreover,the GC-MS fingerprints of the volatile oil extracted from A.officinarum in Hainan shared a 0.956 similarity with those in Guangdong.Therefore,the volatile oil extracted from A.officinarum growing in Hainan can be a substitute for that in Xuwen,Guangdong in food and spice.
