Objective To establish the quality standard for porcine cardiac blood(PCB)and porcine blood(PB)as processing excipi-ents of Menghe Medical School.Methods Fifteen batches of PCB and PB samples(as freeze-dried powders)were collected.They were identified by traits,polymerase chain reaction(PCR),infrared spectroscopy,and peptide fingerprinting combined with chemometrics.The contents of moisture,total ash,acid-insoluble ash,extract,iron,nitrogen,transferrin(Tf),and hydrolyzed amino acids were determined.Results The samples were systematically analyzed using the established methods.The results showed that PCB,PB,and other animal blood could be differentiated by PCR.PCB and PB could be distinguished by infrared spectroscopy and peptide fingerprint-ing combined with chemometrics.It was recommended that the moisture content in both PCB and PB should not exceed 8.0%;the total ash in PCB should not exceed 8.0%,and that in PB should not exceed 11.0%;the acid-insoluble ash in PCB should not exceed 0.50%,and that in PB should not exceed 1.20%;the extract content should not be less than 42.0%;the nitrogen content should not be less than 10.0%;the Tf content should not be less than 0.10%;the iron content in PCB should not be less than 0.20%,and that in PB should not be less than 0.18%;the hydrolyzed amino acids content in PCB should not be less than 36.0%,and that in PB should not be less than 32.0%.Conclusion This study supplements and improves the quality evaluation criteria for PCB and PB as excipients,provid-ing a scientific basis for establishing quality standards for PCB,PB,and their processed decoction pieces.
