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).

In this work, the first phytochemical comparison performed on the polar fractions of two different phenotypes of Mentha aquatica L. having pink-violet and white flowers, is reported. This comparison was conducted through both a classical phytochemical analysis and a metabolomic one by means of spectroscopic and spectrometric approaches. Twenty-seven compounds were identified in both phenotypes. Most of them were evidenced in both. Anyway, all these compounds possess chemotaxonomic, pharmacological and nutritional value.

This work reports the phytochemical analysis of the ethanolic extract obtained from the leaves of Agathis robusta (C. Moore ex F. Muell.) F.M.Bailey. The methodology utilised during this study comprised classical chromatographic and spectroscopic techniques. Six compounds were identified: agathisflavone (1), 7?-O-methyl-agathisflavone (2), cupressuflavone (3), rutin (4), shikimic acid (5) and (2S)-1,2-Di-O- [(9Z,12Z,15Z)-octadeca-9,12,15-trienoyl]-3-O-?-d-galactopyranosyl glycerol (6).

In this study, a phytochemical analysis was performed, for the first time, on Iris marsica I. Ricci e Colas. In particular, the attention was focused on the constituents of the roots. Twenty-one compounds were isolated by column chromatography and were analyzed/identified by NMR spectroscopy and mass spectrometry.

In this work, the first phytochemical analysis ever performed on the unripe female cones of Wollemia nobilis W. G. Jones, K. D. Hill & J. M. Allen was described. The analysis evidenced the presence of a new derivative of sandaracopimaric acid together with rare diterpenoid derivatives and known compounds of chemosystematic and bioactivity relevance. Some of these were evidenced in the species or in the family for the first time during this study. The further implications of the isolated compounds in the field of chemosystematics, pharmacology and nutraceutics were discussed.

In this work, an interesting application of phytochemistry for ethnopharmacological purposes was reported. In particular, the total phytochemical analysis of a single sample of Ajuga reptans L. (Lamiaceae) collected in Central Italy was carried out in order to provide a rationale for the use of this plant in folk medicine. This analysis was conducted on the volatile oil fraction by gas chromatography–mass spectroscopy (GC-MS) and on the polar one by means of classical column chromatography and nuclear magnetic resonance and MS.

In this work, the fifth part of an ongoing phytochemical study on Wollemia nobilis was reported. The attention was now focused on the male reproduction organs of which the content in both primary and secondary metabolites was analyzed. Twenty compounds, belonging to seven different classes of natural compounds, were identified from the ethanolic extract by means of Column Chromatography and NMR and MS Spectroscopy. They all represent new compounds for the studied organ whereas some of them are also new constituents of the genus or even previously undescribed phytochemicals.

In this work, the half-matured female cones of the rare species, Wollemia nobilis, were studied for their phytochemical

In this work, the first phytochemical analysis ever performed on the fruits of Styrax officinalis L. (Styracaceae) collected from a population vegetating in the Mounts Lucretili National Park (Italy) was reported.

In this work, the first phytochemical study on the total polar fraction of Linaria purpurea (L.) Mill. was performed by means of column chromatography and NMR and MS analysis. Seven compounds were identified i.e. pheophytin a (1), methyl-pheophorbide a (2), linaride (3), antirrhide (4), antirrhinoside (5), linarioside (6) and shikimic acid (7), belonging to three different classes of natural compounds. Compound (2) represents a new compound for the family as well as compound (1) is for the genus and compounds (3, 6, 7) are for the species.
