| Abstract: |
| The content of soybean isoflavone in soybean from different producing areas and varieties in Heilongjiang province was detected by HPLC, and the traceability index of soybean isoflavone was screened by using the difference of soybean isoflavone monomer content in varieties and producing areas. The results showed that generally, the content of soybean isoflavone monomer was significantly different among soybean from different varieties in the same area(p<0.05), but there was no significant difference in the content of soybean isoflavone monomer among soybean from different varieties in different areas(p>0.05). Therefore, the content of soybean isoflavone monomer in different varieties of soybean could be used as the characteristic index of soybean isoflavone traceability. |
