The extraction of antioxidant from soybean

In this research, the effect of extraction time and amount of soy powder in solvent extraction from are considered for the study. Extraction is a process to obtaining something from mixture or compound by chemical or physical methods. Solvent extraction is used to extract and purify isoflavones from defatted soy flour. Isoflavones appear to protect against hormone-related disorders such as breast cancer and prostate cancers. Most of natural antioxidants occur as phenols, polyphenols, and flavonoids, three large and related families of antioxidant compounds. Natural has been used since a long time ago for preservation of meat, herb and spices. Natural antioxidant can be found in almost all plant, microorganism, fungi and animal tissue. Flavonoids constitute a large group of naturally occurring plant phenolic compounds. Flavonoids, including flavones, flavonol, isoflavones, flavonones, and chalcones occurs in all type of plant tissue. Flavones and flavonol are found in almost every plant, especially in the leave and petal. Daidzein and Genistein belongs to the isoflavone class of flavonoids that proved be found in soybean. Genistein is the strongest antioxidant followed by daidzein for the second position in soybean
