ABSTRACT
Objective:To improve the quality of Yangxueyufa granules and establish the quality standard. Methods:A TLC method was used for the qualitative identification of Radix Polygoni Multiflori,Fruetus Lyeii,Radix Rehmanniae,Radix Salviae Miltiorrhizae and Fruetus Ligustri Lucidui. Moreover,peoniflorin was determined by HPLC. Results:The TLC spots were clear with highly specificity. The linear relationship of peoniflorin content was good within the range of 14. 3- 286. 0μg·ml-1(r =0. 999 4),and the average recovery was 96. 61%(RSD = 0. 86% ,n = 9). Conclusion:The method is simple,accurate and reliable with good reproducibility,which can be used for the quality control of Yangxueyufa granule.
ABSTRACT
Objective:To establish the quality standard of Fuzhengkangliu pills to further improve the quality. Methods:A TLC method was used for the qualitative identification of Rhizoma Polygoni Cuspidati, Radix Salviae Miltiorrhizae, Radix Astragali Mongoli-ci, Radix Angelicae Sinensis and Rhizoma Chanxiong. Moreover, baicalin was determined by HPLC. Results: The TLC spots were clear and specific. The linear relationship of baicalin was good within the range of 31-310 μg·ml-1 , and the average recovery was 101. 11% (RSD=1. 26%,n=9). Conclusion: The method is simple, accurate, reliable and reproducible, which can be used for the quality control of Fuzhengkangliu pills.
ABSTRACT
Objective The existing Quality Standards for Qianliean Capsules lack the quantitation control item and therefore cannot completely reflect the quality of the preparation .This study aimed to establish the methods for qualitation and quantitation of Qianliean Capsules . Methods Thin-layer chromatography ( TLC) was used for the qualitative identification of Radix Salviae miltior-rhizae, Rhizoma curcumae, and Glycyrrhiza uralensis in Qianliean Capsules .The content of hesperidin was determined by high-per-formance liquid chromatography ( HPLC) , and the method of determination was systematically evaluated . Results TLC spots were clear with a strong specificity .The content of hesperidin showed a good linear relationship within the range of 11 .56-310 .00μg/mL (r=0.999 5), with a mean recovery rate of 99.55% and relative standard deviation of 1.93%. Conclusion The qualitation and quantitation methods we established were simple , accurate and reliable , with a good reproducibility , and can be used for the quality control of Qianliean Capsules .
ABSTRACT
Objective Former standards for Yishen Pills only identify angelica root , astragalus root and ligustrum lucidum by thin layer chromatography ( TLC) and there is no test for the content of effective components .The study was to improve the quality of Yishen Pills by perfecting the quality standards . Methods We determined the content of specnuezhenide in Yishen Pills by high-per-formance liquid chromatography(HPLC), with a mobile phase of MeOH-Water, a chromatography column of Agilent TC-C18(2) (4.6 × 250 mm, 5μm), a flow rate of 1.0 mL/min, a column temperature of 25℃, a detection wavelength of 224 nm, and a sample loop volume of 10μL. Results The linear relationship of specnuezhenide content was good in the range of 15.375μg/mL~246.000μg/mL.The relative standard deviation of precision experiment , stablity experiment and repeatablity experiment was 0.44%, 0.95%and 2.65%re-spectively.The average recovery was 99.60%.The qualified standard for specnuezhenide in Yishen Pills was ≥0.3 mg/g. Conclusion The method is simple , accurate and reliable , with good reproducibility , and it is applicable for the quality control of Yishen Pills .
