Sesquiterpene constituents of the liverwort Calypogeia muelleriana

The lipophilic constituents of the liverwort Calypogeia muelleriana were investigated. A new sesquiterpene hydrocarbon, maali-1,3-diene, and two sesquiterpene alcohols with an aromadendrane skeleton, 3-hydroxyledene and 4,5-dehydroviridiflorol, were isolated and identified. The structure elucidation was carried out mainly by NMR spectroscopic techniques (1H-, 13C-, 1H1H-COSY-, HMQC-, HMBC- and NOESY experiments). The majority of the constituents of the liverwort volatiles show a conspicuous biogeneric relationship, which becomes even more obvious in the stereochemical correlations.

Three ent-secoaromadendrane-type sesquiterpene hemiacetals and a bicyclogermacrene from Plagiochila ovalifolia and Plagiochila yokogurensis

A new ent-secoaromadendrane-type sesquiterpene hemiacetal, plagiochiline G, was isolated from Plagiochila ovalifolia. Four new ent-sesquiterpene hemiacetals, plagiochiline H and I, and two pungent methoxyplagiochilines A1, A2 and non-pungent methoxyplagiochiline C were also isolated from P. yokogurensis. The methoxylated plagiochilines A1, A2 and C were derived from the plagiochilines A and C during the extraction procedure. A new germacrene, ent-3α-acetoxybicyclogermacrene, ent-maaliol and the previously known ent- aromadendrane-type sesquiterpenes have been obtained from P. yokogurensis. The structures of the new compounds were elucidated by 1H NMR spectral data and by chemical correlation.
