The content of phytoestrogen on legume plants

Abstract

There are many plant-derived bioactive nonnutrients that can confer significant health benefits. Among these phytochemicals is the broad class of nonsteroidal estrogens called phytoestrogens. These phytoestrogens and their metabolites have many potential hormonal and nonhormonal activities that may explain some of the biological effects of diets rich in phytoestrogens. Phytoestrogens are plant (predominantly legumes) substances, that have stuctural and functional similiarity to 17β-estradiol, that influence a variety of biological processes. Phytoestrogens are widely used in the human reproductive system, but in livestock, it has not been used yet. Prior study on its role livestock, as a first step, it needs to be exploring the content of phytoestrogen on legumes plants. This study was aimed to determine the content of phytoestrogens of various legumes plants (soya bean straw, peanut straw and green bean straw) by using KLT Densitometry method with genistein standard. The research found that from several legume plants, the legume plant that contained soy phytoestrogens was only soya bean straw either dried using a drying oven or using a freeze dryer content with genistein of each was 0,498 g/100 g dry matter, and 1,748 g/100 g dry matter, uspectinely.
