Karyological data of some plant species native to South Italy

2019

The somatic chromosome number, karyotype morphology, geographical distribution and ecology of five plant species from the indigenous flora of southern Italy and Sicily are presented. The study includes in particular four species of Allium subgen. Allium (Allium agrigentinum, A. apulum, A. diomedeum, A. chamaespathum), Ptilostemon greuteri and Salvia ceratophylloides. Five out six of these species are strict endemics and all of them are very rare and differently threatened based on the IUCN criteria. Karyotype microphotographs for all taxa are provided and their karyotype morphology is discussed.

Clerodane diterpenoids from Salvia splendens.

2006

Four new clerodane diterpenoids, salvisplendins A-D (1-4), have been isolated from an acetone extract of the flowers of SalVia splendens, together with an artifact (5), arising from salvisplendin D (4) by addition of diazomethane, and the already known clerodane olearin (6). The structures of the new compounds (1-5) were established mainly by 1D and 2D NMR spectroscopic studies and, in the case of salvisplendin A (1), by chemical correlation with splenolide B (7). Complete 1H and 13C NMR assignments for olearin (6), not published hitherto, are also reported.

Anti-tumor activity of the methanolic extracts of Salvia menthifolia

2012

In the present research we investigated the anti-proliferative activity of Salvia menthifolia Ten. (formerly Salvia menthaefolia), Lamiaceae, on a glioblastoma cell line, since up to date poor therapeutic results have been reported for treatment of malignant glioblastoma. Methanol extracts from different anatomical parts of S. menthifolia were tested on DBTRG-05MG cell line by MTT assay. The most active primary stems extract was also evaluated for apoptosis induction. Results confirmed the anti-tumor property of all the organs and demonstrated that the primary stems extract induced apoptosis after 4 h with the highest values of DNA fragmentation after 6 to 24 h. Some extracts were also HPLC…

Metabolites from Mediterranean plant: characterization and trasformation. chemotaxonomic assessmentand biological activity

2016

Questo progetto di ricerca ha lo scopo di ampliare le conoscenze di alcune piante appartenenti alla flora Mediterranea. Le piante da studiare sono state scelte in seguito ad un’attenta analisi bibliografica tra specie poco sudiate. La scelta è quindi ricaduta su nove specie appartenenti al genere Anthemis, due specie appartenenti al genere Pulicaria e sulle specie di Tetraclinis articulata, Salvia argentea, Ajuga tenorei, Ballota hispanica, Moluccella Spinosa e Thapsia garganica. Di esse sono stati preparati ed identificati i componenti degli oli essenziali e successivamente effettuati su di essi i saggi antibatterici. Dagli estratti delle specie di Tetraclinis articulata e Ajuga tenorei so…
