Abstract:
The vitamin E content in soybean from Northeast China and North America that were harvested in the same place and same year were extracted by the method of ultrasonic wave，and the contents of α、γ、δ-tocopherol and total vitamin E were analyzed by HPLC with C18-reverse phase HPLC column as solid phase，and methanol as mobile phase(Flow = 1.5 mL. min-1).The fluorescence detector(Ex = 295nm，Em = 330nm)was used as detector.The results showed that 144 soybean materials based on the contents of α、γ、δ-tocopherol and total vitamin E were all classified in to three class of high，middle and low by cluster analysis.The contents of α、γ、δ-tocopherol and total vitamin E in soybeans from Northeast China were obviously higher than those from North America.
