| Abstract: | Isoflavonoids were extracted from soybean with alcohol as extractant assisted by microwave irradiation.The extracted isoflavonoids were measured by spectrophotography.The effect factors such as microwave power,volume fraction of ethanol,the rate of garlic slurry to ethanol and microwave irradiation time on extraction of isoflavonoids from soybean were investigated.The obtained optimum conditions were as follows: that microwave power was 400 W,volume fraction of ethanol was 50%,the rate of soybean slurry to ... |
