In the course of our study on Salvia species for the identification of potential new crops with diversified value in the Mediterranean agriculture(1-3), we considered Salvia tingitana Etl. The species is a perennial shrub original from the Arabian region (4) and cultivated as an ornamental plant. The surface extract, obtained by rinsing the...

Among the marine sponges, the genera Ircinia and Sarcotragus are the major source of polyprenylated compounds, both benzoquinones and benzohydroquinones [1, 2]. Biological studies conducted on hydroxylated 2-octaprenylhydroquinones have shown antioxidant activity [3], antifouling activity against Balanus amphitrite Darwin cyprids [4], and...

The dichloromethane extract obtained from the aerial parts of Salvia buchananii Hedge was investigated for its antimicrobial properties following a bioassay-oriented fractionation approach. The extract displayed a clear inhibitory activity against several Gram-positive multidrug-resistant clinical strains including Staphylococcus aureus,...

A bioguided separation of the "exudate" mixture of the fresh aerial parts of Salvia buchananii Hedge (Hedge, 1963) was carried out. The exudate as well as several row fractions obtained during the purification process displayed a clear inhibitory activity on selected Gram positive multidrug resistant clinical strains, including Staphylococcus...

The genus Salvia is known to possess bioactive constituents, commonly found in the complex secretion product of the aerial parts of these plants (1). The study of the chemical constituents of this surface exudate material (2) may thus be useful for the discovery of biologically active compounds, particularly terpenoids (3), that have shown...

The major diterpenoids of the exudate of the fresh aerial parts of Salvia corrugata Vahl., demethylfruticuline A (1) and fruticuline A (2), showed significant antibacterial activity [1] and inhibited in vitro the synthesis of biofilm of multiresistant strains of Staphylococcus and Enterococcus [2]. In order to identify efficient in vitro...

Salvia chamaedryoides Cav. (Lamiaceae) is a Mexican species [1] recently introduced in the Ligurian agricultural market as an ornamental plant, and for extractive purposes [2]. The dichloromethane extract of the aerial parts was investigated for its antimicrobial and hypoglycaemic properties with the aid of bioassay-­‐oriented fractionation....

Demethylfruticuline A and fruticuline A, the most abundant compounds from the surface extract of Salvia corrugata Vahl., have shown antibacterial, antitumor and cytotoxic activities. In order to obtain these icetexane diterpenes from in vitro cultures of S. corrugata, protocols were developed for callus production, micropropagation and shoot...

The antimicrobial activity of the surface exudate obtained by rinsing the aerial parts of S. buchananii Hedge (Lamiaceae) [1] with CH2Cl2 was preliminary evaluated by testing 10 μl of 2-fold dilutions (ranging from 1000 mg/L to 64 mg/L) on selected multi-drug-resistant Gram-positive strains, appropriately seeded on agar plates [2]. A clear halo...

A surface extract of the aerial parts of Salvia chamaedryoides afforded 13 diterpenes (1−13), with seven compounds (1, 3, 4, 7−9, 12) described for the first time. The structures of the new compounds were established using 1D and 2D NMR spectroscopic methods, HRESIMS, and ECD data. The potential hypoglycemic effects of the crude extract,...
