The leaves and roots contain saponins and polyphenols(Hutapea, 1994). It also contains protein, carbohydrates, fat, fiber, calcium, iron, phosphorus, potassium, sodium, vitamin B1, vitamin B2, vitamin C, and niacin(Handri and Rafira, 2003). The content of the compounds in the bean’s role in proliferation, differentiation, and protein synthesis in target cells of different.
