ABSTRACT
Objective:To develop a method for the determination of Zinc gluconate and citric acid in Shanpu-Jianpi granule. Methods:The air-acetylene was selected as flame type, the detection wavelength was 213.9 nm, the gas flow rate was 0.9 L/min, the burner height was 7.2 mm, and deuterium lamp was used as background correction. The width of passband was 1.0 nm. Titration, sodium hydroxide was used to determine the citric acid with phenolphthalein as an indicator.Results:The content of Zinc Meletin, exhibited good linearity ( r=0.999 8) among the ranges of 0.1-2.0 μg/ml and the average recovery was 94.06% ( RSD=1.67%). The average recovery of citric acid was 94.65% ( RSD=0.91%). Conclusions:The method is simple, accurate and high sensitivity which can be used for determination of Zinc gluconate and citric acid in Shanpu-Jianpi granule.
ABSTRACT
Based on the histories of moxibustion and moxibustion apparatus, this paper studies two basic patterns and the problem of categorizing about moxibustion instrument, and summarizes and experimentalizes its mechanism. Its developing way is brought up.
