nyasol nyasol nyasol, also known as cis-hinokiresinol or as (z)-hinokiresinol, is a lignan that is found in anemarrhena asphodeloides. it has estrogenic activity, acting as a selective agonist of the erβ, and hence is a phytoestrogen. in addition, (-)-nyasol has been found to inhibit the production of eicosanoids and nitric oxide in vitro and shows anti-inflammatory effects. nyasol names iupac name 4,4'-bis other names cis-hinokiresinol; (z)-hinokiresinol identifiers cas number 96895-25-9 3d model (jsmol) interactive image pubchem cid 6915833 unii lk6ch9d7ur inchi inchi=1s/c17h16o2/c1-2-14(15-7-11-17(19)12-8-15)6-3-13-4-9-16(18)10-5-13/h2-12,14,18-19h,1h2/b6-3-/t14-/m1/s1key: veaunwqyymxirb-jhaqobcdsa-n smiles c=c(/c=c\c1=cc=c(c=c1)o)c2=cc=c(c=c2)o properties chemical formula c17h16o2 molar mass 252.313 g·mol−1 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references
