Scapania undulata

Satake and coworkers131 studied lead accumulation and location in the shoots of the aquatic liverwort, Scapania undulata, in stream water (Pb content, 20 p-gl-1) at a mine in England. The lead concentration in the shoots ranged from 7 to 24 mgPbg-1 on a dry weight basis, giving an enrichment ratio of 3.5 x 105 — 1.2 x 106. Lead was localized in the cell wall131. [Pg.903]

Longifolene has since been found to be widely distributed in the family Pinaceae (7). ( —)-Longifolene has been isolated from the liverwort Scapania undulata (L.) Dum. (S) and from the fungus Helmintho-sporium sativum (142). [Pg.51]

Yi Cadinene (246) has been isolated from Scapania undulata (2). It was quite difficult to distinguish between (+ )-Yi-cadinene (246) and (+ )-y-cadinene (245) by H-NMR, CD and GC because of their similarities (2). Structure (246) for yi-cadinene was confirmed by difference in ORD data between (246) and (245), and by the acid-catalyzed rearrangement of (246) which produced 10-epi-zonarene (249), calamenene (250) and calacorene (254) (2). [Pg.45]

The absolute configuration of caryophyllene (255) found in Scapania undulata was the same as that isolated from tracheophytes (2). Andersen and coworkers (2) suggested that (255) might be arised from trans-trans-farnesyl pyrophosphate in S. undulata. Caryophyllene is one of the common sesquiterpene hydrocarbons in the Hepaticae, particularly in the Frullaniaceae (27). [Pg.46]

Along with longifolane- and longipinane-types sesquiterpenes, (-h)-a-himachalene (436), (—)-P-himachalene (437) and (-h)-y-himachalene (438) have been isolated from Scapania undulata (2, 223). All himachalanes isolated are antipodal to those obtained from higher plants. [Pg.73]

Huneck and Klein (160) reported isolation and characterization of the essential oil obtained from seven Jungermanniales species and one Metzgeriales species. From Scapania undulata, (—)-longifolene (439) and (—)-longiborneol (443) were isolated and their structures established by comparison of their spectral data with those of authentic samples. This represented first isolation of terpenoids from the Hepaticae and of sesquiterpenoids antipodal to those found in higher plants. The presence of longifolene (439) and isolongifolene (440) in Scapania species was revealed by GC-MS analysis (314). [Pg.73]
