Abstract

Abstract: In this work, a phytochemical study performed on the leaves of the rare species, Wollemia nobilis W.G. Jones, K.D. Hill & J.M. Allen, is reported. By means of classical column chromatography and NMR Spectroscopy and Mass Spectrometry, nine compounds were evidenced. These were: pheophorbide a (1 ), isocupressic acid (2 ), acetyl-isocupressic acid (3 ), sandaracopimaric acid (4 ), agathic acid (5 ), 7–4′-4‴-tri- O -methyl-agathisflavone (6 ), 7–4′-7″-4‴-tetra- O -methyl-agathisflavone (7 ), caffeic acid (8 ) and shikimic acid (9 ). Compared to our previous phytochemical analysis on the male cones, some further compounds were identified i.e. compounds1, 5, 6, 7 and8 . This confirmed the previous chemotaxonomic considerations of the species but also added new ones which were discussed within the text. In addition, a possible different accumulation of secondary metabolites in the tissues and organs of this plant was even noticed. Graphical abstract: Highlights: Phytochemical analysis. Wollemia nobilis leaves. Nine compounds were identified. The chemotaxonomic relevance of the compounds was explained. The systematic relevance of the compounds was explained.
