Background & Objective: Isoflavones occurring in soybean seed have a positive effect on the health of humans, especially in cancer prevention.

This positive impact may be a result of their antioxidant properties, estrogenic activity, or a combination of both mechanisms.

The purpose of this study was to quantify and compare levels of three major isoflavones in soybean seeds from three sources (Alghab area, Faculty of Agriculture, imported from China).

Material& methods: Isoflavones have been extracted from soybean seeds by ethanol-water mixture (80%:20%), then they have been analyzed by high performance liquid chromatography (HPLC).

Results: The results showed that soybean seeds taken from Alghab area contain the highest concentration of isoflavones (genistin 660.51µg/gr, diadzin 390.33 µg/gr and glycitin 130.59µg/gr) then comes imported seeds (genistin 628.44µg/gr, diadzin 350.65µg/gr and glycitin 100.81µg/gr) and Faculty of Agriculture( genistin 54.43µg/gr , diadzin 300.61µg/gr and glycitin 78.55 µg/gr), respectively.

Conclusion: Soybean seeds contain high percentage of isoflavones, and this Quantities of isoflavons differ according to their sources
