arctiin arctiin arctiin is a lignan found in many plants of the family asteraceae, particularly the greater burdock (arctium lappa) and centaurea imperialis, and in trachelospermum asiaticum, saussurea heteromalla, and forsythia viridissima. it is the glucoside of arctigenin. arctiin names iupac name (3r,4r)-4--3-oxolan-2-one identifiers cas number 20362-31-6 y 3d model (jsmol) interactive image chembl chembl388452 y chemspider 90827 y kegg c16915 y mesh arctigenin pubchem cid 100528 unii tm5rq949k7 y comptox dashboard (epa) dtxsid20942519 inchi inchi=1s/c27h34o11/c1-33-18-6-4-14(10-20(18)34-2)8-16-13-36-26(32)17(16)9-15-5-7-19(21(11-15)35-3)37-27-25(31)24(30)23(29)22(12-28)38-27/h4-7,10-11,16-17,22-25,27-31h,8-9,12-13h2,1-3h3/t16-,17+,22+,23+,24-,25+,27+/m0/s1 ykey: xojvhliynsozoo-swobocgesa-n yinchi=1/c27h34o11/c1-33-18-6-4-14(10-20(18)34-2)8-16-13-36-26(32)17(16)9-15-5-7-19(21(11-15)35-3)37-27-25(31)24(30)23(29)22(12-28)38-27/h4-7,10-11,16-17,22-25,27-31h,8-9,12-13h2,1-3h3/t16-,17+,22+,23+,24-,25+,27+/m0/s1key: xojvhliynsozoo-swobocgeby smiles o=c2oc(cc1ccc(oc)c(oc)c1)2cc4ccc(o3o((o)(o)3o)co)c(oc)c4 properties chemical formula c27h34o11 molar mass 534.558 g·mol−1 melting point 110 to 112 °c (230 to 234 °f; 383 to 385 k) except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). n verify (what is yn ?) infobox references arctiin and arctigenin have shown anticancer effects in animal research. they have been found to act as agonists of the adiponectin receptor 1.
