Compare of Different Identifing Methods on Sanghuang

Abstract:

In this study,the different identification methods for Sang huang were compared.Sang huang was identified by modality,molecular marker and HPLC fingerprint alignment,and the identifing result was validated one another from different levels.The results showed that(1) the morphological difference of strain could not use as the index for strain identification.(2) the phylogenetic tree from HPLC fingerprint alignmen and from rDNA ITS showed more consistent.(3) molecular marker identified other strains as P.baumii and P.linteus.Based on the above results,the component analysis could regard as assistant means for identifying strains,but was not exact and dependable in relative to nucleic acid analysis.
