Abstract：This study conducted a comparative analysis of the physicochemical indices,antioxidant substance content,and antioxidant capacity of four types of Dalbergia odorifera T.Chen honey,three types of Guizhou specialty honey(blueberry,galla chinensis,and loquat T.Chen honey),and manuka honey,aiming to investigate the antioxidant characteristics of Dalbergia odorifera T.Chen honey.The results indicated that the physicochemical indices of all eight types of honey complied with relevant industry standards.The total amino acid content in the four types of Dalbergia odorifera T.Chen honey was higher than that of manuka honey,while the total phenol and flavonoid contents were lower than those of manuka honey but higher than those of the three types of Guizhou specialty honey.Overall,the scavenging abilities of Dalbergia odorifera T.Chen honey against DPPH,ABTS+,and·OH radicals showed no significant difference compared to manuka honey(P＞0.05),but were stronger than those of the three types of Guizhou specialty honey.Moreover,specific samples of Dalbergia odorifera T.Chen honey,H1 and H4,exhibited significantly stronger scavenging abilities against OH radicals than manuka honey(P＜0.05).The content of total phenols,total amino acids,vitamin C,and vitamin B,in eight types of honey was positively correlated with the IC50 values of the three radical scavenging rates,while the flavonoid content was only positively correlated with the IC50 value of·OH radical scavenging.Overall,the Dalbergia odorifera T.Chen honey possessed good nutritional quality and strong antioxidant activity,and suitable for further research and promotion as a high-end novel honey source.
