A Phytochemical Study of Some Nepalese Liverworts

Pandey, Rita (2000) A Phytochemical Study of Some Nepalese Liverworts. MSc(R) thesis, University of Glasgow.

Abstract

This thesis describes a phytochemical investigation of three members of the Hepaticae family (liverworts) from Nepal. The species examined were Marchantia paleacea Betrol subsp. paleacea, Marchantia papillata Raddi subsp. grossibarba (steph) Bishl and Plagiochasma appendiculatum Lehm et. Lindenb. M. paleacea yielded the bisbibenzyl derivatives marchantins A, C and D, p-hydroxybenzaldehyde, 2-hydroxy-3,7-dimethoxyphenanthrene, the corresponding 1,1-dimer and the interesting new compound 3,4-dihydro-8-hydroxy-4-(4-hydroxyphenyl)-isocoumarin. Marchantins A and C and the above phenanthrene were obtained from M. papillata while marchantins A and B and riccardin D were isolated from Plagiochasma appendiculatum. The structures were assigned from 1 D and 2D 1H and 13C NMR spectra and were confirmed, where appropriate, by comparison with published data. The thesis is prefaced by a general review of the Hepaticae and their chemical constituents.
