ABSTRACT
Radix Codonopsis is a traditional tonic medicine commonly used in traditional Chinese medicine. It contains sugar, alkaloids, polyynes, glycosides, terpenoids, and other chemical constituents. It has the functions of regulating blood sugar, promoting hematopoietic function, anti-hypoxia, anti-stress, alleviating fatigability, enhancing the body immunity, anti-aging, regulating gastric contraction, anti-ulcer, and other pharmacological activities. This paper summarized the literature on the chemical composition and their pharmacological activities of Codonopsis and provided the basis for the further development and utilization of Codonopsis resources.

Methods By using content analysis approach, the basic situation of achievements, the research content of achievements, and assessment and application of achievements were classified and statistically analyzed by classifying and statistical function of computer. Results The provinces that rank the top of national scientific and technological achievements of the three species of Chinese herbal were Gansu, Hebei and Shandong. The achievements were mainly undertaken by college or university, hospital and scientific research institutions. The source of project achievements mainly originated from local project and optional project. The research content of the achievements largely focused on the fields like drug therapeutic effect, pharmaceutical preparation, cultivation techniques, storing and processing. Conclusion In the database (HowNet) of national scientific and technological achievements, the amplification of national scientific and technological achievements of the three species of Chinese herbal is slow, the achievements mainly focus on application technology, the conversion rate of achievements is low, and large amount of data of achievement items in database is missing.
ABSTRACT
Objective To establish the method for content determination of total flavonoids and polysaccharides in Radix Codonopsis Lanceolatae from Mount Taishan.MethodsThe content of the total flavonoids was determined by UV spectrophotometry and the polysaccharide content was measured with the phenol-sulphuric acid method.ResultsThe optimal detective wavelength was 510nm for the total flavonoids.Satisfactroy linear relationship with the Absorbability was achieved when the mass concentration of rutin was within a range of 8～48?g/ml(r=0.9986).The average recovery rate was 99.31%(RSD=1.82%,n=5).The optimal detective wavelength was 490nm for the polysaccharides.There was good linear relationship between the Absorbability and the content of glucose in a range of 5～50?g/ml(r=0.9964) with an average recovery of 99.12%(RSD=1.49,n=4).ConclusionThis method is sensitive,simple and accurate,and it can be used for the quality control of Radix Codonopsis Lanceolatae from Mount Taishan.
ABSTRACT
Objective Chromatography fingerprint of Radix Codonopsis of different age from Shanxi province was studied to provide the reference for the science appraisal of intrinsic quality of Radix codonopsis. Method A RP-HPLC method was applied on GraceSmart-RP18 (250 mm?4.6 mm, 5 ?m) column with acetonitrile-0.1% acetic acid gradient elution as mobile phase, and the flow-rate was 0.6 mL/min. The detection wavelength was at 268 nm and the column temperature was at 30 ℃. Result Chromatography fingerprint of Radix Codonopsis can demonstrate obviously the difference and the similarity of Radix Codonopsis of different age. The RSD were lower than 3% in the precision, stability and the repetitiveness trial, and the codonopsis pilosula alkyne glucoside can be used as the reference to identify the active composition of Radix Codonopsis. Conclusion The method was simple, reproducible and reliable. The integrity of fingerprint can be used to supply the reference for the quality control of Radix Codonopsis from Shanxi provice.
ABSTRACT
Object To study the difference between Radi x Codonopsis (RC) and Radix Astragali (RA) on the central nerv ous system. Methods Sleeping was induced by pentobarbital sodium and ether. The water maze was used. Results Both RC and RA could prolong the sleeping time induced by pentobarbital sodium and ether. RC and RA had effect on the scopolamine-indu ced study and memory disturbance of mice. Conclusion The effect of RC on prolonging the sleeping time induced by pentobarbital sodium and ether is better than that of RA. On the study and memory disturbance induced by sc opolamine, RC is also better tha n RA.
ABSTRACT
Object To compare the effects of Radix Codonopsis (RC) and Radix Astragali (RA) on ECG of experimental myocardial ischemia rats. Methods The model of myocardia ischemia was made by injection of pituitrin (Pit) in rats. The changes of ECG were observed with three parameters, viz. the heart rate, the locomotions of T wave and S T section. Results Both RC and RA can decrease the run up of T wave in ECG of rats with experimental myocardial ischemic injury in which RC is superior to RA. While RA has stronger effect on the slowering of the heart rate than RC.Conclusion Both RC and RA have protective effect on experimental myocardial ischemic injury induced by Pit.
