High-Performance Liquid Chromatography/Electrospray Ionization Tandem Mass Spectrometry (HPLC-ESI-MSn) Analysis and Bioactivity Useful for Prevention…
2019
This study aimed at evaluating and comparing the chemical profile obtained by HPLC-ESI-MSn analysis, the inhibitory activity of enzymes linked to obesity (α-amylase, α-glucosidase, and lipase) and the antioxidant properties (DPPH, ABTS, FRAP, and β-carotene bleaching tests) of ethanol extracts of bulbs (BE) and aerial parts (APE) from Allium commutatum Guss. (known in Italy as “aglio delle isole”). The chemical profile revealed alliin as the main abundant compound with values of 31.5 and 38.8 mg/g extract for BE and APE, respectively. APE is rich also in quercetin (38.5 mg/g extract) and luteolin (31.8 mg/g extract). Bulbs extract exhibited the highest activity as inhibitor of enzymes linke…
Diterpenoids from the roots and aerial parts of the genus Stachys
2011
The occurrence of diterpenoids from roots and aerial parts of the species of the genus Stachys (Lamiaceae, Labiatae) is reviewed. The presence of these diterpenoids in other taxa and their biological properties have been also reviewed
Phytochemical Studies on Ptilostemon greuteri Raimondo & Domina (Compositae)
2012
Ptilostemon greuteri Raimondo & Domina is described as a new species and its growth is limited to the area of the province of Trapani. Essential oils of aerial parts of P. greuteri were analized by gas chromatography-mass spectrometry (GC-MS). The analysis of acetonic extract of aerial parts led to identification of triterpenes components: α-amyrin, β-amyrin, α-amyrin acetate, β-amyrin acetate, lupeol, lupeol acetate and taraxasterol. CC and preparative TLC of acetonic extracts has yielded lignan lactone and a sesquiterpene lactone that have been isolated previously from other Ptilostemon species.
CHEMICAL COMPOSITION OF THE ESSENTIAL OILS OF SOME TAXA OF THE GENUS CLINOPODIUM (LAMIACEAE) FROM SICILY
2017
The genus Clinopodium L. (Lamiaceae) is known for its medical uses in folk medicine and as a spice in Italian food. Recently, several taxa previously assigned to Satureja L. and Calamintha Mill. have been transferred to this genus (1). Pharmacological studies reveal, for instance, that Calamintha nepeta (L.) Savi [Clinopodium nepeta Kuntze subsp. nepeta], commonly known as “nepetella”, exhibits cholagogue, expectorant, sedative and antibiotic properties (2); furthermore, the essential oil of its aerial parts showed an antifungal activity (3). The apical flowering parts and leaves of Clinopodium vulgare L. are used in popular medicine for their carminative and emmenagogue properties (1); rec…
