通过单标记(QAMS)建立了淫羊藿中13种化学成分的多组分定量分析方法,包括新乙醇酸,绿原酸,低温绿原酸,magnopolidine,金丝桃素,epimedinA,EpimedinB,epimedinC,淫羊藿苷,宝火苷Ⅱ,射箭门A,淫羊藿苷消退Ⅰ,和宝火石Ⅰ,从而探讨该方法对不同产地、不同品种淫羊藿药材质量评价的可行性和准确性。通过科学准确的调查实验方法,采用外标法测定淫羊藿中13种化学成分的含量。同时,淫羊藿苷被用作内标,淫羊藿苷与新乙醇酸的相对校正因子,绿原酸,低温绿原酸,magnopolidine,金丝桃素,epimedinA,EpimedinB,epimedinC,淫羊藿苷,宝火苷Ⅱ,射箭门A,淫羊藿苷消退Ⅰ,并成立了宝火石Ⅰ,分别。新乙醇酸的含量,绿原酸,低温绿原酸,magnopolidine,金丝桃素,epimedinA,EpimedinB,epimedinC,淫羊藿苷,宝火苷Ⅱ,射箭门A,淫羊藿苷消退Ⅰ,通过QAMS计算了淫羊藿中的baohuosideⅠ。最后,比较实测值与计算值的差异,验证QAMS在测定中的准确性和科学性。各组分的相对校正因子具有较好的重复性,外标法的结果与QAMS的结果无明显差异。以淫羊藿苷为内标,QAMS同时测定新乙醇酸,绿原酸,低温绿原酸,magnopolidine,金丝桃素,epimedinA,EpimedinB,epimedinC,淫羊藿苷,宝火苷Ⅱ,射箭门A,淫羊藿苷消退Ⅰ,保火苷Ⅰ可用于淫羊藿的定量分析。
The quantitative analysis of multicomponents by single-marker(QAMS) was established for 13 chemical components of Epimedii Folium, including neoglycolic acid, chlorogenic acid, cryo-chlorogenic acid, magnolidine, hypericin, epimedin A, epimedin B, epimedin C, icariin, baohuoside Ⅱ, sagittatoside A, icariin subside Ⅰ, and baohuoside Ⅰ, so as to investigate the feasibility and accuracy of this method in evaluating the quality of Epimedii Folium materials from different origins and different varieties. Through the scientific and accurate investigation of the experimental method, the external standard method was used to determine the content of 13 chemical components in epimedium brevieornu. At the same time, icariin was used as the internal standard, and the relative correction factors of icariin with neoglycolic acid, chlorogenic acid, cryo-chlorogenic acid, magnolidine, hypericin, epimedin A, epimedin B, epimedin C, icariin, baohuoside Ⅱ, sagittatoside A, icariin subside Ⅰ, and baohuoside Ⅰ were established, respectively. The contens of neoglycolic acid, chlorogenic acid, cryo-chlorogenic acid, magnolidine, hypericin, epimedin A, epimedin B, epimedin C, icariin, baohuoside Ⅱ, sagittatoside A, icariin subside Ⅰ, and baohuosideⅠ in Epimedii Folium were calculated by QAMS. Finally, the difference between the measured value and the calculated value was compared to verify the accuracy and scientific nature of QAMS in the determination. The relative correction factor of each component had better repeatability, and there was no significant difference between the results of the external standard method and those of QAMS. With icariin as the internal standard, QAMS simultaneously determining neoglycolic acid, chlorogenic acid, cryo-chlorogenic acid, magnolidine, hypericin, epimedin A, epimedin B, epimedin C, icariin, baohuoside Ⅱ, sagittatoside A, icariin subside Ⅰ, and baohuoside Ⅰ can be used for quantitative analysis of Epimedii Folium.
