Study on Improvement of Quality Standard of Yishen Jiangu Pills
OBJECTIVE: To improve the quality standard of Yishen Jiangu pills. METHODS: To conduct microscopic identification on radix rehmanniae
semen cuscutae
poria
rhizoma dioscoreae and rhizoma alismatis
to preform thin-layer chromatographic identification on cornus officinalis
rhizoma atractylodis and salviae miltiorrhizae
and the high performance liquid chromatography was adopted to carry out quantitative analysis on monosidine and strychnine in the preparation. RESULTS: The characteristics of microscopic identification of radix rehmanniae
semen cuscutae
poria
rhizoma dioscoreae and rhizoma alismatis were obvious
the spots of thin-layer chromatograms of cornus officinalis
rhizoma atractylodis and salviae miltiorrhizae were clear. The morroniside showed good linearity in the range of 0. 368-0. 828 μg
with r2= 0. 999 9( n = 6)
the average recovery was 97. 55%
and the RSD = 1. 57%;strychnine showed good linearity in the range of 0. 392-0. 882 μg
with r2= 0. 999 9( n = 6)
the average recovery was97. 29%
and the RSD = 0. 82%. CONCLUSIONS: This method is comprehensive and accurate
which has effectively improved the quality control of this preparation.
