The recent progress of drugs with biotechnique
Yang Yulong, Ren Haixiang
1995, (5): 261-265.
Abstract:
The recent progress in research and development of biotechnical drugs and biochemical drugs were outlined in this paper. The relationship between biotechnique and biologics was discussed and application of modern biotechnique to some biologics was introduced.

A study on norfloxacin cream
Li Xinsheng, Wang Li, Liao Chen
1995, (5): 292-296.
Abstract:
Norfloxacin cream is an oil-in-water (O/W) emulsion,This paper emphasizes on the experimental study of its prescription design, preparative procedure, quality standard, stability,stimulation and laboratroy inhibition of bacteria.
Study on the quality standards of Huichun Zhibao Oral Liquid (HZOL)
Guo Tao, Shi Guobing, Chi Weiquo, Ma Yan, Gao Shengchuan, Hn Baofeng, Yang Song
1995, (5): 296-299.
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:
Determination of nitrofurantoin in urine by second derivative spectrophotometry
Wan Xinxiang, Zhang Li, Chen Chucheng, Xia Zhixiang
1995, (5): 303-305.
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.

Determination of chlorhexidine acetate in chlorhexidine acetate gargle by second derivative spectrophotometry
Wu Feihua, Wang Tao
1995, (5): 310-312.
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%
