Abstract:
In this paper, thin layer chromatography (TLC) was used to destinguish the active components of Ginseng,Hairy Antler, and Epimedium Herb in HZOL and high-performace Liquid chromatorgaphy (HPLC) to determine quantitatively the content of icariin,one of the main active components in epimedium herb in HZOL. The method was accurate,sensitive,and reproducable with the average recovery=98.97% and RSD=1.53% (n=3).

Abstract:
Limulus amebocyte lysate test study for detection endotoxin in metronidazole injection.Experiments proved that between rabbit pyrogen test and limulus amebocyte lysate test comparative studies for detcting endotoxin in metrondazol injection results were in good agreement.

Abstract:
The paper teported the determination of nitrofuratoin in urine by second derivative spectroscopy. The method consists of direct extraction of the drug by the use of ethyl acetate from the acidic urine and determination of the nitrofurantoin concerntration by measuring the amplitude between the maximum and minimum of the second derivative signal at 374-377nm. The method had a detection limit of 1.5mg/L with recovery of 98% and RSD was less than 3%. The both methods of second derivaive and HPLC had notable relativity.The method could apply to the pharmacokinetics study of nitorfurantoin.

Abstract:
The paper reportes the direct determination of chlorhexidine Acetate Gargle by Second derivative spectrophotometry. The result shows:This method is simple, accurate and reproducible. The callbration curve is linear in the range of 50μg/ml to 200μg/ml.γ=0.9997,RSD=0.6%
