OCCURRENCE OF ENT-SESQUITERPENE IN THE JAPANESE MOSS PLAGIOMNIUM-ACUTUM - FIRST ISOLATION AND IDENTIFICATION OF THE ENT-SESQUI-TYPE AND DOLABELLANE-TYPE DITERPENOIDS FROM THE MUSCI

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