Abstract:

To establish HPLC fingerprint of cultivated Sanghuangporus(Sanghuang), screen out the signature component of Sanghuangporus through chemical pattern recognition, the content determination method of Sanghuangporus was established based on this index. According to the corresponding methods in the general rules of The Chinese Pharmacopoeia (four parts) in the 2020 edition, the fingerprint of Sanghuangporus was established, and the similarity was evaluated by using the similarity evaluation system of traditional Chinese Medicine Chromatographic Fingerprint 2004 Version A to determine the common peak. The content of Hypholomine B in Sanghuangporus was also determined. HPLC fingerprints of 10 batches of Sanghuangporus were established, with 12 common peaks, and the similarity was greater than 0.92. The results of HCA, PCA and OPLS-DA were consistent, and the samples were divided into two categories. The injection volume of Hypholomine B had a good linear range with its peak area in the range of 1.25-20.00 μg (R2=0.999 9). The RSD values of precision, stability and repeatability were all less than 2.0% (n=6). The recovery rate was 95%-99%, and the RSD was 1.48%. The content of Hypholomine B in 10 batches of mulberry yellow samples ranged from 0.15% to 0.95%. The fingerprint can be combined with HCA, PCA and OPLS-DA to comprehensively evaluate the quality of Sanghuangporus. The method is stable and reliable, providing reference for the quality evaluation of Sanghuangporus.

Key words: Sanghuangporus, fingerprints, high performance liquid chromatography, styrylpyranones, Hypholomine B
