Flavonoid-7-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Apigenin 7-arabinoside is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Apigenin 7-arabinoside can be found in chicory, which makes apigenin 7-arabinoside a potential biomarker for the consumption of this food product. 4',5,7-Trihydroxyflavone; 7-O-a-L-Arabinopyranoside Apigenin 7-arabinoside C20H18O9 402.3515 402.095082174 5-hydroxy-2-(4-hydroxyphenyl)-7-[(3,4,5-trihydroxyoxan-2-yl)oxy]-4H-chromen-4-one 5-hydroxy-2-(4-hydroxyphenyl)-7-[(3,4,5-trihydroxyoxan-2-yl)oxy]chromen-4-one 77610-88-9 OC1COC(OC2=CC3=C(C(O)=C2)C(=O)C=C(O3)C2=CC=C(O)C=C2)C(O)C1O InChI=1S/C20H18O9/c21-10-3-1-9(2-4-10)15-7-13(23)17-12(22)5-11(6-16(17)29-15)28-20-19(26)18(25)14(24)8-27-20/h1-7,14,18-22,24-26H,8H2 ASMYXLDPYBVDFS-UHFFFAOYSA-N belongs to the class of organic compounds known as flavonoid-7-o-glycosides.
