文摘采用电感耦合等离子体原子发射光谱法,对红花椒(陕西韩城、四川汉源、四川茂汶、甘肃武都)和青花椒(云南昭通、贵州关岭、四川金阳、四川汉源、重庆江津)9大主产地的80个样品中21个无机元素含量进行测定。采用主成分分析(principal component analysis,PCA)和偏最小二乘判别分析(partial least squaresdiscriminationanalysis,PLS-DA)对红花椒和青花椒中无机元素进行综合评价,PCA和PLS-DA将80个花椒聚为9组,PLS-DA分类效果更佳,并能将红花椒和青花椒有效区分,从元素组成角度揭示了红花椒和青花椒的亲缘关系和地域分布特征。研究证明多元素分析结合PLS-DA可作为一种花椒品种和产地识别的有效工具,对于产地溯源和品种鉴定具有重要意义。
