Delta-viniferin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Delta-viniferin can be found in grape wine, which makes delta-viniferin a potential biomarker for the consumption of this food product. Delta-viniferin is a resveratrol dehydrodimer. It is an isomer of epsilon-viniferin. It can be isolated from stressed grapevine (Vitis vinifera) leaves. It is also found in plant cell cultures. or in wine. It can also be found in Rheum maximowiczii . d-Viniferin C28H22O6 454.478 454.141638428 5-[(2S,3S)-5-[(E)-2-(3,5-dihydroxyphenyl)ethenyl]-2-(4-hydroxyphenyl)-2,3-dihydro-1-benzofuran-3-yl]benzene-1,3-diol 5-[(2S,3S)-5-[(E)-2-(3,5-dihydroxyphenyl)ethenyl]-2-(4-hydroxyphenyl)-2,3-dihydro-1-benzofuran-3-yl]benzene-1,3-diol 62218-13-7 [H][C@@]1(OC2=C(C=C(\C=C\C3=CC(O)=CC(O)=C3)C=C2)[C@]1([H])C1=CC(O)=CC(O)=C1)C1=CC=C(O)C=C1 InChI=1S/C28H22O6/c29-20-6-4-18(5-7-20)28-27(19-12-23(32)15-24(33)13-19)25-11-16(3-8-26(25)34-28)1-2-17-9-21(30)14-22(31)10-17/h1-15,27-33H/b2-1+/t27-,28+/m0/s1 LILPTCHQLRKZNG-LPGNHZEISA-N belongs to the class of organic compounds known as 2-arylbenzofuran flavonoids.
