Nyasol

Nyasol, also known as cis-hinokiresinol or as (Z)-hinokiresinol, is a lignan that is found in Anemarrhena asphodeloides.^[1][2][3][4] It has estrogenic activity, acting as a selective agonist of the ERβ,^[5] and hence is a phytoestrogen.^[6][7][4] In addition, (-)-nyasol has been found to inhibit the production of eicosanoids and nitric oxide in vitro and shows anti-inflammatory effects.^[8]
