Published Online March 2022 in Hans. analyze the structural correlation between two plants and between these phenolics. Through a li-
terature search from 2010, it is found that there are 39 phenolics in grape or Ampelopsis plants,
mainly including resveratrol, trans-ε-viniferin, ampelopsin A, myricetin-3-O-β-D-glucoside, kaemp-
ferol-3-O-α-L-rhamnoside, (+) taxifolin, 3,5,7-trihydroxychromone, catechin, epicatechin-3-O-gallate,
proanthocyanidin, caffeic acid, p-coumaric acid, and methyl gallate. The structural correlation
analysis showed that these phenolics could be classified into four types: stilbene and oligostilbene
type, chromogen and flavonoid type, catechin and anthocyanin type, and phenolic acid and its es-
ter type. Further analysis indicated that, the oligostilbenes can be polymerized from stilbenes; and
flavonoids can be transformed from chromogen; while catechins can be polymerized into antho-
cyanins. These structural correlations further suggest that: 1) there may be a bio-conversion rela-
tionship between two subtypes in the same phenolic type; 2) And there is a certain genetic rela-
tionship between grape plant and Ampelopsis plant.
