| 摘要 |
A novel methylated catechin is provided which has stronger antiallergic activity than conventionally known methylated catechins such as epigallocatechin-3-O-(3-O-methyl)gallate and epigallocatechin-3-O-(4-O-methyl)gallate. The epigallocatechin-3-O-gallate derivative is represented by the chemical formula I:
(wherein R 1 to R 6 are each a hydrogen atom or a methyl group, and at least three of R 1 to R 6 are methyl groups) or an isomer thereof. |
