Dihydromyricetin

CAS 27200-12-0

Dihydromyricetin is a vine tea constituent whose name points to its relation to myricetin. A double bond in myricetin's central ring is replaced by a single bond, while a nearby carbonyl remains. The resulting structure has two stereocenters. The reference material for this CAS specifies the (2R,3R) form. Different arrangements can have the same mass, so weighing the molecule cannot resolve its configuration. Researchers have examined how stable that configuration is in the vine tea context. The question matters because a purified standard and a handled plant sample are not the same environment. A concentration and a stereoisomer distribution describe different aspects of the material. To know what a measurement tells us, we need to know which forms the method actually distinguishes.
