ChemInform Abstract: Two New Sesquiterpene Derivatives from the Tunisian Endemic Ferula tunetana Pom.
2010
A new sesquiterpene ester, tunetanin A (1), a new sesquiterpene coumarin, tunetacoumarin A (2), together with eight known compounds, i.e., coladin (3), coladonin (4), isosmarcandin (5), 13-hydroxyfeselol (6), umbelliprenin (7) propiophenone (8), beta-sitosterol (9), and stigmasterol (10), were isolated from the roots of Ferula tunetana. Their structures were elucidated on the basis of extensive spectroscopic methods, including 1D- and 2D-NMR experiments and MS analysis, as well as by comparison with published data. The cytotoxicity of compounds 1-7 towards two human colon cancer cell lines, HT-29 and HCT 116, was evaluated. Compounds 3, 4, and 6 showed weak cytotoxic activities.
Phytochemical investigation and antitumor activity of coumarins from Sicilian accession of Ferulago nodosa (L.) Boiss. roots
2023
Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area being present in Crete, Greece, Albania, and probably in Macedonia. From the roots of this accession of species, not previously investigated, four coumarins, grandivittin, aegelinol benzoate, felamidin and aegelinol, and two terpenoids, (2E)-3-methyl-4-[(3-methyl-1-oxo-2-buten-1yl)oxy]-2-butenoic acid and pressafonin-A, were isolated and spectroscopically characterized. The last one was never detected in Ferulago species. The evaluation of the anti-tumor effects of F. nodosa coumarins on colon cancer HCT116 cells showed only a modest effect on reduction of tumor cell viability. For aegelinol, the red…
Composition and biological activities of the essential oil from a Sicilian accession of Prangos ferulacea (L.) Lindl
2019
Prangos ferulacea (L.) Lindl. (Fam. Apiaceae), is an orophilous species of eastern Mediterranean and western Asia which possesses several biological properties, which are worthy of exploitation in different fields. With the aim to provide new insights into the phytochemistry and pharmacology of this species, a local accession growing in Sicily (South Italy) was investigated as well. Notably, the P. ferulacea essential oil chemical composition and the antioxidant, anti-acetylcholinesterase (AChE) and cytotoxic activities have been studied. This analysis allowed to identify a new chemotype and to report good biological results for this oil. © 2019 Informa UK Limited, trading as Taylor & F…
Ecophysiology of germination in Sicilian population of Ferula communis (Umbelliferae)
2010
Ferula communis L. is an umbelliferous plant widespread in the Mediterranean basin and particularly abundant in Sicily and Sardinia islands (Italy). In this species, two chemotypes have been distinguished: one is poisonous and responsible of hemorrhagic syndrome of livestock, known as ferulosis, while the other one (non- poisonous) has anticancer activity due to the presence of daucane esters. In Sicily the dry stem of this plant has commercial applications in special manufactured products. The object of the research was to investigate the germination ecophysiology of nine Sicilian populations of F. communis, in order to establish the correct germplasm conservation of the chemotypes economi…
Antimicrobial and Antioxidant Activities of Coumarins from the Roots of Ferulago campestris (Apiaceae)
2009
We report the isolation of several coumarins and the stereochemical assessment of some pyranocoumarins, as well as the antibacterial and antioxidant activities of the three most abundant ones (grandivittin, agasyllin and aegelinol benzoate) isolated from the roots of Ferulago campestris collected in Sicily and of the hydrolysis product (aegelinol). Aegelinol and agasyllin showed antibacterial activity against nine ATCC and the same clinically isolated Gram-positive and Gram-negative bacterial strains. At a concentration between 16 and 125 μg/mL both coumarins showed a significant antibacterial effect against both Gram-negative and Gram-positive bacteria. In particular the ATCC strains Staph…
In vitro antitumor effects of the cold-water extracts of Mediterranean species of genus Pleurotus (higher Basidiomycetes) on human colon cancer cells
2014
The aim of this study was to evaluate whether the cold-water extracts of Pleurotus eryngii var. ferulae (CWE-Pef) and Pleurotus nebrodensis (CWE-Pn), 2 of the most prized wild and cultivated edible mushrooms, can affect the tumor phenotype of human colon cancer HCT116 cells. Our results showed that treatment with CWE- Pef and CWE-Pn resulted in a significant inhibition of the viability of HCT116 cells and promoted apoptosis, as also demonstrated by the increase of Bax-to-Bcl-2 messenger RNA ratio. Moreover, we observed that both extracts were able to inhibit cell migration and to affect homotypic and heterotypic cell-cell adhesion. It also was found that treatment with CWE-Pef and CWE-Pn ne…
Ferulago nodosa Subsp. geniculata (Guss.) Troia & Raimondo from Sicily (Italy): Isolation of Essential Oil and Evaluation of Its Bioactivity
2020
Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area. The object of the present study is Sicilian F. nodosa subsp. geniculata (Guss.) Troia & Raimondo, classified as an endemic F. nodosa subspecies. Aerial parts of this plant species were subjected to hydrodistillation to obtain an essential oil. A total of 93 compounds were identified with 2,3,6-trimethyl benzaldehyde (19.0%), spathulenol (9.0%), (E)-caryophyllene (5.4%), and caryophyllene oxide (5.4%) as the main components. The biological activities of F. nodosa essential oil were also investigated. This oil showed an interesting antioxidant potential in a 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sul…
Antibacterial activity and cytotoxicity of selected Egyptian medicinal plants.
2011
Medicinal plants have been used as a source of remedies since ancient times in Egypt. The present study was designed to investigate the antibacterial activity and the cytotoxicity of the organic extracts from 16 selected medicinal plants of Egypt. The study was also extended to the isolation of the antiproliferative compound jaeschkeanadiol p-hydroxybenzoate (FH-25) from Ferula hermonis. The microbroth dilution was used to determine the minimal inhibitory concentration (MIC) of the samples against twelve bacterial strains belonging to four species, Providencia stuartii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli, while a resazurin assay was used to assess the cytoto…
