Abstract:
Objective To establish a method of simultaneously quantitative analysis for multi-components by single marker( QAMS)of galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin and apigenin in two species of Chamomiles from Xinjiang. Methods By using apigenin as the internal standard,the relative correction factors( RCF)of galuteolin,apigenin-7-glucoside,7-methoxycoumarin and luteolin were set and determined by UPLC. The contents of galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin and apigenin in 11 samples of Chamomiles were authentically determined by the external standard method,to verify the accuracy of QAMS. Results There is a good linear relationship within the range of standard curve for five compounds by the external standard method(r〉0. 999 3);the average recovery was 99. 7%,97. 5,98. 8%,100. 9%,99. 1%,for galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin and apigenin,respectively,with RSD as 1. 8%,0. 6%,0. 5%, 1. 8% and 1. 9%,respectively. The RCF for pigenin-7-glucoside,galuteolin,7-methoxycoumarin and luteolin to apigenin was 1. 441,2. 308,1. 117,1. 490,respectively,with RSD as 0. 07%,0. 04%,0. 09% and 0. 18%,respectively. No significant difference between the quantitative results by QAMS and external standard method was observed. Conclusion It is practical to determine content of galuteolin,apigenin-7-glucoside,7-methoxycoumarin,luteolin with RCF and apigenin by using external standard method,for the deficiency and expensive of the standard reference.
