Alfalfa (Medicago sativa L.) is from Fabaceae family that has several flavonoid compound in roots and shoots. in alfalfa the major phytoalexin is medicarpin. In this study, total phenolic and flavonoid compounds and phenylalanin ammonia lyase (PAL) activity in different stages of development were measured. In this research the concentration of medicarpin by HPLC were studied in different stages of development. The lowest and highest level of the concentration of medicapin were in seedling stage and budding stage of growth, respectively. The results indicated that contents of total phenolic compounds and total flavonoid and PAL activity increase with developmental stage ,but decrease in flowering stage of growth.
