The hydrodistillation products of the liverwort Bazzania japonica were separated by preparative gas chromatography (GC) and investigated by spectroscopic methods. Seven unknown compounds were isolated and identified by GC-MS and NMR. Four of them, the norsesquiterpene hydrocarbons
A dichloromethane and a methanol extract of the liverwort Bazzania trilobata showed antifungal activity against the phytopathogenic fungi Botrytis cinerea, Cladosporium cucumerinum, Phythophthora infestans, Pyricularia oryzae and Septoria tritici. Bioautography on thin-layer chromatograms was used
The biosynthesis of gymnomitranes in the liverworts Reboulia hemisphaerica (L.) Raddi and Bazzania trilobata (L.) Gray was investigated. Labelling experiments with 1-13C-, 2-13C- and 6,6-D2 glucose, 2,2-D2- and 4,4-D2 mevalolactone and tissue cultures of the liverworts were carried out.
Extracts of the liverwort Bazzania novae-zelandiae were cytotoxic, with selective activity against human tumor cell lines. Bioactivity-directed isolation work showed that the new compound naviculyl caffeate (1) was the main cytotoxin. This structure was confirmed by synthesis from the co-occurring
Volatile components of seven species of the Bazzanioideae sub-family (Lepidoziaceae) native to New Caledonia, including three endemic species (Bazzania marginata, Acromastigum caledonicum and A. tenax), were analyzed by GC-FID-MS in order to index these plants to known or new chemotypes. Detected
