Abstract:
In order to identify Schisandrae chinensis （Turcz.） Baill and Schisandrae sphenanthera Rehd. et Wils. by SPME-GC fingerprint combined with cluster analysis and discriminant analysis,the volatile components from Schisandrae chinensis （Turcz.） Baill and Schisandrae sphenanthera Rehd. et Wils. were extracted by Head Space Solid Phase Microextraction.The chemical components in Schisandrae chinensis （Turcz.） Baill and Schisandrae sphenanthera Rehd. et Wils. was ultrasonically extracted in methanol.The fingerprint of the extract were assayed with capillary gas chromatography to establish the GC fingerprint of Schisandrae chinensis （Turcz.） Baill and Schisandrae sphenanthera Rehd. et Wils. and SPSS were used for similarity evaluation and clustering analysis and discriminant analysis.The results showed in the seven Schisandrae chinensis（Turcz.） Baill and Schisandrae sphenanthera Rehd. et Wils. samples from different cultivation areas，the similarity between Schisandrae sphenanthera Rehd. et Wils. from different cultivation areas were greater than 0.95;also the similarity between Schisandrae chinensis （Turcz.） Baill from different cultivation areas were greater than 0.95;while the similarity between Schisandrae chinensis （Turcz.） Baill and Schisandrae sphenanthera Rehd. et Wils. were smaller than 0.26.Clustering analysis could discriminate Schisandrae chinensis （Turcz.） Baill from Schisandrae sphenanthera Rehd. et Wils.. The accurate rate of discriminant analysis of four unknown samples were reached 100%.
