摘　　要：为比较不同品种菊花的品质特征,本文采用HPLC法测定其游离糖类及游离氨基酸的含量。结果表明,不同品种菊花中游离糖类主要成分是果糖和葡萄糖,蔗糖和麦芽糖未检出,总游离糖类含量约为9.07～18.76g/100 g,其中黄山贡菊中含量最高,为18.76 g/100 g,黄菊中最低,为9.07 g/100 g;其总游离氨基酸含量约为0.563～2.806 g/100 g,七月菊中含量最高,为2.806 g/100 g,杭白菊中最低,为0.563 g/100 g。The experiments were conducted with HPLC methods to determine the contents of free sugars and amino acids in various species of medicinal Flos chrysanthemi. The results showed that the main free sugars in Flos chrysanthemi were fructose and glucose;there were no sucrose and maltose. The total contents of free sugars in Flos chrysanthemi were in the range of 9.07 - 18.76 g/100 g. The highest content of total free sugars was found in Gongju with 18.76 g/100 g, while the lowest contem in Huangju with 9.01 g/lO0 g. The total levels of free amino acids in Flos chrysanthemi ranged from 2. 806 to 0. 563 g/100 g,among which Qi yueju showed the highest level of total free amino acids with 2. 806 g/100 g,Hang baiju showed the lowest level of total free amino acids with 0.563 g/100 g.
