pseudohypericin pseudohypericin pseudohypericin is an aromatic polycyclic dione that is very closely related to hypericin. it is found most commonly in the st. john's wort family of plants, namely in hypericum perforatum. in preliminary studies in animal models, pseudohypericin has shown antiviral effects. it may also contribute to the potential antidepressant effect of hypericum perforatum extracts. pseudohypericin names preferred iupac name 1,3,4,6,8,13-hexahydroxy-10-(hydroxymethyl)-11-methylphenanthroperylene-7,14-dione identifiers cas number 55954-61-5 3d model (jsmol) interactive image 3dmet b03886 chebi chebi:8605 chembl chembl1614664 chemspider 4445065 echa infocard 100.111.993 ec number 611-335-2 kegg c10392 pubchem cid 4978 unii mq0u4663zo comptox dashboard (epa) dtxsid00204541 inchi inchi=1s/c30h16o9/c1-7-2-9(32)19-23-15(7)16-8(6-31)3-10(33)20-24(16)28-26-18(12(35)5-14(37)22(26)30(20)39)17-11(34)4-13(36)21(29(19)38)25(17)27(23)28/h2-5,31,34-39h,6h2,1h3key: nodgubigzkatom-uhfffaoysa-n smiles cc1=cc(=o)c2=c(c3=c(c=c(c4=c3c5=c6c7=c(c1=c25)c(=cc(=o)c7=c(c8=c(c=c(c4=c86)o)o)o)co)o)o)o properties chemical formula c30h16o9 molar mass 520.449 g·mol−1 log p 4.5 except where otherwise noted, data are given for materials in their standard state (at 25 °c , 100 kpa). infobox references
