1.2. Composition
The composition of Pueraria Candollei variant Mirifica (Pueraria Mirifica) is:
The Chromene compounds Miroestrol, a phytoestrogen known to be the primary active ingredient[6][7][8] as well as both Deoxymiroestrol and Isomiroestrol;[9][10] the 'main' chromene in name, Miroestrol, is at approximately 0.002% of the plant by dry weight[11][12]
The isoflavone Puerarin at 20.25-22.43mg/100g (Puerarin is a glycoside of Genistein[2]and also found in Psoralea corylifolia) as well as both Soy Isoflavones Daidzein (5.73-10.44mg/100g free form and 15.51-23.62mg/100g of the glycoside Daidzin) and Genistein (1.27-2.10mg/100g free form, 38-48.44mg/100g of the glycoside Genistin).[12][2][13] Estrogenic isoflavones in Pueraria Mirifica including glycosides total 8.4-10.2% dry weight[14]
Kwakhurin, a prenylated isoflavone[15] that has some estrogenic activity (weak relative to the chromenes[12]) at 0.0064-0.0067% dry weight[11] or less[12]
Puemiricarpene, a pterocarpene[12]
Coumestrol[16]
