ABSTRACT
OBJECTIVE: To study the adsorption and desorption behavior of macroporous adsorhption resin AB-8 for polysaccharides in exocarp of Ginkgo biloba L. and its effect factors. METHODS: The optimum purification conditions were investigated by singal factor experiments. RESULTS: The optimum conditions were as follows: the follow rate was 1.0 ml/min, solution concentration was 10 mg/ml and the pH was 7.4-7.6. CONCLUSION: AB-8 have an upper adsorption capacity for polysaccharides in exocarp of Ginkgo biloba L. and the elution is easy. The purification of its production is 81.3%.

The latest research progress on quantitative determination methods of main active components-lignans from Schisandra chinensis and its preparations has been summarized, such as spectrophotometry, thin-layer chromatography scanning, high performance liquid chromatograpy, gas chromatography-mass spectrometry and capillary electrochromatography. The characteristics and application areas of every analytical method have also been stated. It offers reference on quality control of crude drug and its preparations of S. chinensis.
