Abstract:Objective To improve the quality uniformity of Epimedium Herb Decoction Pieces. Methods The contents of epimedin C and icariine in Epimedium Herb Decoction Pieces were used as indexes. Homogenization software was used to homogenize seven batches of decoction pieces. The changes of relative standard deviation (RSD) and fingerprint similarity of different batches of index component content before and after homogenization were compared to verify the homogenization effect. Results After homogenization, RSD of epimedin C and icariine content in all batches of decoction pieces decreased from 52.49% and 26.07% to 6.13% and 2.63%, respectively. The similarity of fingerprints was above 0.960. Before homogenization, RSD and fingerprint similarity of each index component content were significantly different, but decreased significantly after homogenization. Conclusion The changes of RSD of index component content and similarity degree of fingerprint indicate that homogenization of different batches of decoction pieces can significantly improve quality uniformity. This study evaluate the homogenization results from the perspective of index component content and fingerprint similarity, and achieve good homogenization effect, which can be applied to the feeding process of industrial production of Traditional Chinese medicine preparations, and can provide reference for the homogenization study of epimedium herb and other decoction pieces.
