- 中文摘要:
Degradative and other data described below have shown that the tannin of unripe fruits of persimmon (Diospyros virginiana) actually contains (+)-gallocatechin unit in the structure and must be regarded as condensed flavonoid pigments, probably of similar structure to the polymeric proanthocyanidin from avocado seed.
The possible structure of the proanthocyanidin from persimmon fruits is proposed tentatively as a polymer of 5, 7, 3', 4', 5'-pentahydroxyflavanonal. - 英文摘要: --
