Occurrence of ent-Sesquiterpene in the Japanese Moss-Plagiomnium acutum : First Isolation and Identification of the ent-Sesqui-and Dolabellane-type Diterpenoids from the Musci

Abstract

The ether extract of the Japanese moss Plagiomnium acutum was chromatographed on silica gel and Sephadex LH-20 to give ent-β-cedrene and 3, 7-dolabelladiene-18-ol which has been isolated fro brown algae. To the authors' knowledge, this is the first isolation and identification of sesquiterpenoids from the Musci and the first record of ent-β-cedrene from the plant kingdom.
