Anthraquinones are organic compounds containing either anthracene-9,10-quinone, 1,4-anthraquinone, or 1,2-anthraquinone. Physcion 8-glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Physcion 8-glucoside can be found in garden rhubarb, which makes physcion 8-glucoside a potential biomarker for the consumption of this food product. 1,3,8-Trihydroxy-6-methylanthraquinone, 8CI; 3-Me ether, 8-O-b-D-glucopyranoside Physcion 8-glucoside Physcion 8-O-beta-D-monoglucoside C22H22O10 446.4041 446.121296924 1-hydroxy-3-methoxy-6-methyl-8-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-9,10-dihydroanthracene-9,10-dione 1-hydroxy-3-methoxy-6-methyl-8-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}anthracene-9,10-dione 26296-54-8 COC1=CC2=C(C(O)=C1)C(=O)C1=C(C=C(C)C=C1OC1OC(CO)C(O)C(O)C1O)C2=O InChI=1S/C22H22O10/c1-8-3-10-16(19(27)15-11(17(10)25)5-9(30-2)6-12(15)24)13(4-8)31-22-21(29)20(28)18(26)14(7-23)32-22/h3-6,14,18,20-24,26,28-29H,7H2,1-2H3 WLXGUTUUWXVZNM-UHFFFAOYSA-N belongs to the class of organic compounds known as anthraquinones.
