Partial acidic hydrolysis coupled PMP-HPLC analysis was applied to indentify and characterize polysaccharides from Ganoderma lucidum spores from different zones in China.Chromatographic fingerprint of the polysaccharide was built using 15 different sources of Ganoderma lucidum spore powder samples and 19 common peaks were found.The similarity between products from the same zone was much higher than 0.97,while it was lower but still greater than 0.80 when the products originated in different zones.There are quite a lot of differences among Ganoderma lucidum spore and other species spore and between spore and fruit body of Ganoderma lucidum.The similarities and differences may be used as main basis for quality control,identification from different origins and parts of Ganoderma and their adulteration detection.
