This paper expounds the design of sample collection system for clinical inspection,which works as the interface of CLIS and CIS.The solution to such problems as bar-code technology,grouping application and quality insurance are discussed,and a new plan for mobile collection is suggested.

OBJECTIVE:To establish the method for simultaneous determination of the content of berberine hydrochloride, baicalin and osthole in Jinchan zhiyang capsules. METHODS:HPLC method was adopted. The determination was performed in Hypersil BDS C18 column with mobile phase consisted of methanol-acetonitrile-0.1%phosphoric acid-three triethylamine(50∶30∶19∶1, V/V/V/V) at the flow rate of 1.0 mL/min. The detection wavelengths were set at 265 nm (berberine hydrochloride),280 nm (baicalin)and 322 nm(osthole). The column temperature was set at 30 ℃,and sample size was 10 μL. RESULTS:The linear range of berberine hydrochloride,baicalin and osthole were 80-800 ng(r＝0.999 8),60-600 ng(r＝0.999 9),60-600 ng(r＝0.999 6),respectively. RSDs of precision,stability and reproducibility tests were all lower than 2.0%. The limits of quantitation were 80,60,60 ng,respectively,and the limits of detection were 24,20,20 ng,respectively. The recovery rates were 97.4%-98.3%(RSD＝0.33%,n＝6),98.4%-99.6%(RSD＝0.42%,n＝6)and 96.9%-99.0%(RSD＝0.92%,n＝6),respectively. RSDs of durability tests were all lower than 1.2%. CONCLUSIONS:The method is simple, accurate, precise, stable, reproducible and durable. It can be used for simultaneous determination of berberine hydrochloride,baicalin and osthole in Jinchan zhiyang capsules.

OBJECTIVE:To establish the method for simultaneous determination of berberine hydrochloride and baicalin in Jianpi zhixiening granules. METHODS:HPLC switching walvelength method was adopted. The determination was performed on Hypersil BDS C18 column with mobile phase consisted of methanol-0.45％ phosphoric acid solution-triethylamine(50:49:1,V/V/V) at the flow rate of 1.0 mL/min. The detection wavelength was set at 265 nm(berberine hydrochloride)and 280 nm(baicalin). The column temperature was set at 30 ℃,and sample size was 10 μL. RESULTS:The linear range of berberine hydrochloride and baicalin were 60.3-312.8 ng(r=0.9997)and 81.5-368.9 ng(r=0.9999). The limits of quantitation were 0.6668,0.7740 ng,andthe limits of detection were 0.2226,0.2580 ng,respectively. RSDs of intermediate precision,stability and repeatability tests were all lower than 1.0％. The recoveries were 96.48％-99.30％(RSD=1.06％,n=6) and 95.20％-99.39％(RSD=1.66％,n=6), respectively. RSDs of durability test were all lower than 2.0％. CONCLUSIONS:The method is simple, precise, stable, reproducible,accurate and durable. It can be used for simultaneous determination of berberine hydrochloride and baicalin in Jianpi zhixiening granules.
