Definition:A para-terphenyl that consists of 1,4-diphenylbenzene substituted by acetyloxy groups at positions 5' and 6', hydroxy groups at positions 4 and 4'', a (3-phenylpropanoyl)oxy group at position 3' and a (3-hydroxybutanoyl)oxy group at position 2'. It is isolated from the fruit body of the mushroom Paxillus curtisii and exhibits radical scavenging activity
