An object of the invention is to find in nature a compound having a degranulation inhibitory action comparable to that of steroidal or non-steroidal degranulation inhibitors, but without any side effect such as hormone action or gastrointestinal disturbances which are observed in these inhibitors, and there is provided a degranulation inhibitor comprising as an active ingredient an ellagic acid derivative of the formula (I):n n[wherein R 1 represents a hydroxy group or methoxy group, and R 2 represents a methoxy group, or R 1 and R 2 are taken together to form a methylenedioxy group, R 3 represents a hydroxy group or methoxy group, and R 4 represents a glucosyloxy group or hydroxy group] nor a salt thereof. |
