Soy isoflavones from Glycine max L.Merill, a type of phytoestrogen are considered as potential cancer chemopreventive compounds especially prostate and breast cancer and has potential ability to reduce the symptoms associated to menopause. They are also used to combat osteoporosis and hyperlipidemia. The major isoflavones in soyabean include daidzein, genistein, glycitein and their glycosides. Thus soy isoflavones are considered as potential candidate for complementary and alternative therapy. Standardization of isoflavone content in Glycine max L.Merill set with the extraction procedure involved and the analytical technique developed. For extraction of isoflavones several extraction methods have been used ranging from solvent extraction by soxhlet, magnetic stirring to more modern sample preparation techniques like supercritical fluid extraction, pressurized liquid extraction, solid phase extraction and ultrasound assisted microwave extraction. Different analytical techniques like UV spectrophotometric, HPLC, capillary electrophoresis, LC-ESI-MS, have been developed to separate and quantify soy isoflavones in all forms, whereas selection of a particular technique depends in the objectives of investigation. A simple and practical approach is needed for routine quality check and quality consistency assurance in between batches. Chromatographic fingerprints as a strategy for standardization of herbal medicine is widely accepted. A novel HPTLC method has been developed and validated for the estimation of individual isoflavone content in different varieties of Glycine max L.Merill.
