ABSTRACT
AIM:To anylsis the chemical constituents of the Caulis of Schisandra from different harvesting time in Jiaohe prefecture for comprehensive utilization of shizandra berry's resource.METHODS:Dexyschisandrin,monosaccharide and oligosaccharide,polysaccharide were taken as statistical indicator and in combination with cluster analysis to compare among them.RESULTS:With colligational comparison,contents of climbing stem collected in November and July approached that of schisandra fruit.Deoxyschisandrin content was the highest in stem in July,polysaccharide content in November,oligosaccharide content in September.CONCLUSION:Chemical pattern recognition can play a role in comparing content of multicomponent of the Caulis of Schisandra and the best harvesting time.
