Abstract

Chemical investigations of the stony coral Alveopora japonica Eguchi (Poritidae) resulted in the isolation of four known compounds (1 - 4). The structures of 1 - 4 were identified as a sterol, ergosta-5,24(28)-dien-$3{\beta}$-ol (1), a mixture of monoacyl glycrols (2), eicosanoic acid and tetracosanoic acid, and two nucleosides, thymine (3) and 2'-deoxythymidine (4), respectively, on the basis of spectroscopic and physicochemical analyses including 1D- and 2D- NMR techniques as well as by comparison of their data with the published values. Compounds 1 - 4 were isolated from this species for the first time. Moreover, these compounds (1 - 4) were found in the genus Alveopora and the family Poritidae for the first time.
