상황버섯 자실체를 80% MeOH 용액으로 추출하고, 추출물을 EtOAc, n-BuOH 및 물로 분배, 추출하였다. 이 중 EtOAc 분획을 silica gel 및 octadecylsilica gel(ODS) column chromatography로 정제하여 4종의 sterol 화합물을 분리하였다. 각 화합물의 화학구조는 NMR, MS 및 IR 등의 스펙트럼 데이터를 해석하여, ergosta-7,24(28)-dien-3${\beta}$-ol (episterol, 1), 5${\alpha}$,8${\alpha}$-epidioxyergosta-6,9(11),22-trien-3${\beta}$-ol (dehydroperoxyergosterol, 2), 5${\alpha}$,8${\alpha}$-epidioxyergosta-6,22-dien-3${\beta}$-ol (ergoterol peroxide, 3), 및 $3{\beta}$,$5{\alpha}$-dihydroxy-6${\beta}$-methoxyergosta-7,22-diene (6-O-methylcerevisterol, 4)로 동정하였다. 이 화합물들은 이번에 상황에서 처음 분리 보고되었다.

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.
