Keyword:  陈皮陈皮素橙皮苷含量测定;
Abstract: 目的:测定陈皮中陈皮素和橙皮苷的含量,为陈皮的有效利用提供科学依据。方法:用70%的乙醇回流提取,采用HPLC法测定陈皮素和橙皮苷的含量。橙皮苷采用甲醇-醋酸-水(35∶5∶60)流动相,检测波长为284nm,柱温为30℃,流速为0.8mL/min;陈皮素采用0.05%磷酸-乙腈(45∶55)为流动相,检测波长为335,柱温为35℃,流速为0.8mL/min。结果:橙皮苷线性方程为:Y1=2.95×106X1+3.46×104(r=0.999 9),线性范围为0.74~7.4μg/mL;陈皮素线性方程为:Y2=5.68×106X2-1.16×105(r=0.999),线性范围为:0.174~1.740μg/mL。测得的陈皮中橙皮苷、陈皮素含量分别为3.619g/100g药材、0.331g/100g药材。结论:此方法简便、快速、准确可靠,可作为陈皮药材的质量控制方法。
