Violanthin

5,7-dihydroxy-2-(4-hydroxyphenyl)-6-[(2S,3R,4R,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-8-[(2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]-4H-chromen-4-one

Violanthin is a member of the class of compounds known as flavonoid 8-c-glycosides. Flavonoid 8-c-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to 8-position of a 2-phenylchromen-4-one flavonoid backbone. Violanthin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Violanthin can be found in rice, which makes violanthin a potential biomarker for the consumption of this food product. Violanthin is isolated from the stems of Dendrobium officinale, has potent antioxidant and antibacterial activities. Violanthin inhibits acetylcholinesterase (AChE) with an IC50 value of 79.80 μM[1].

Isoviolanthin

5,7-Dihydroxy-2-(4-hydroxyphenyl)-8-((2S,3R,4R,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)-6-((2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyltetrahydro-2H-pyran-2-yl)-4H-chromen-4-one

Isoviolanthin is a natural product found in Angiopteris evecta and Passiflora sexflora with data available. Isoviolanthin, a flavonoid glycoside, could markedly inhibit TGF-β1-mediated migration and invasion by deactivating epithelial-mesenchymal transition (EMT) via the TGF-β/Smad and PI3K/Akt/mTOR pathways in HCC cells. Isoviolanthin exhibits no cytotoxic effects on normal liver LO2 cells[1].
