ABSTRACT
Quality control issues overshadow potential health benefits of the edible mushroom Flammulina velutipes, with the detection and isolation of polysaccharides posing particular problems. In this study, multiple-fingerprint analysis was performed using chemometrics to assess polysaccharide quality and antioxidant activity of F. velutipes fruiting bodies from different sources. The authentic source exhibited differences in both oxygen radical absorbance capacity and ferric reducing antioxidant power from foreign sources. IR spectroscopic/HPLC fingerprints of polysaccharide extracts from the authentic source were established and applied to assess the polysaccharide quality of foreign sources. Analysis of IR fingerprints using Pearson correlation coefficient gave correlation coefficient r values of 0.788 and 0.828 for two foreign sources, respectively, indicating distinctness from the authentic source. Analysis of HPLC fingerprints using the supervised method by Traditional Chinese Medicine could not discriminate between sources (r > 0.9), but principal component analysis of IR and HPLC fingerprints distinguished the foreign sources.
