Ampelopsis brevipedunculata (syn. Vitis heterophylla Thunb.), the porcelain berry, is an ornamental plant, native to temperate areas of Asia. It is generally similar to, and potentially confused with, grape species (genus Vitis) and other Ampelopsis species.
The strange blue color of the berries is due to an anthocyanidins-flavonols copigmentation phenomenon.
Ampelopsin B is a stilbene oligomer found in A. brevipedunculata var hancei.
