salvia ringens/抗菌的

The aim of this study was to investigate the antibacterial and the cytotoxic activity of the acetone extract of the flowers of Salvia sclarea and of some natural products (sclareol, sclareolide and ambrox). The antibacterial and the cytotoxic activity were determined by the dilution method.

The study explored the isolation and characterisation of three compounds of high purity salvianolic acid B freeze-dried powder extracted from Salvia miltiorrhiza Bunge. A new salvianolic acid, salvianolic acid V (2) together with two known compounds (3-4) was identified. The antibacterial activity

An efficient preparative procedure for the separation of four antibacterial diterpenes from a Salvia prattii crude diterpenes-rich sample was developed. Firstly, the XION hydrophilic stationary phase was chosen to separate the antibacterial crude diterpenes-rich sample (18.0 g) into three fractions

OBJECTIVE To determine the chemical composition, antioxidant activity and antibacterial properties of essential oils of the aerial parts of Salvia sclareoides (S. sclareoides). METHODS The essential oil of the areal parts of S. sclareoides was obtained by using hydrodistillation method and the

The antioxidant and antibacterial properties of Greek oregano extracts obtained by fractional supercritical fluid extraction (SFE) with carbon dioxide were investigated and compared with the properties of essential oil obtained by hydrodistillation. According to DPPH, hydroxyl radical and superoxide

Due to the great global concern regarding bacterial resistance to antibiotics, an ongoing search for new molecules having antibacterial activity is necessary. This study evaluated the antibacterial and anticandidal effects of a hexane extract from the root of Salvia apiana. Salvia extracts at

The present report examined the effects of essential oils (EOs) from Satureja hortensis L. and Salvia fruticosa M. on the viability and outer membrane permeability of the periodontopathogen Fusobacterium nucleatum, a key bacteria in oral biofilms, as well as the inhibition of matrix

The extended-spectrum beta-lactamase (ESBL) -producing Escherichia coli strains can lead to various infections particularly urinary tract infections. The main objective of this investigation was to evaluate the antibacterial activities of essential oils (EOs) from different Iranian medicinal plants

Ethanolic extracts of Salvia officinalis leaves demonstrated antibacterial activity against Bacillus cereus. Fractionation of the extracts led to the isolation of the most active antibacterial compound, which, from spectroscopic and LC-MS evidence, was proved to be the diterpene, methyl carnosate.

The antibacterial activity of essential oils extracted from medicinal plants (Ocimum gratissimum, L., Cybopogum citratus (DC) Stapf., and Salvia officinalis, L.) was assessed on bacterial strains derived from 100 urine samples. Samples were taken from subjects diagnosed with urinary tract infection

OBJECTIVE Over the last few years, there has been an increasing interest in the use of natural substances for promoting human and animal health. Antibiotic resistance, enhanced by excessive use of antibiotics, has encouraged human and animal health authorities to consider and employ alternative

The EtOAc extract of the liquid fermentation of Alternaria sp. Samif01, an endophytic fungus obtained from Salvia miltiorrhiza Bunge, showed antibacterial activity against several tested bacterial pathogens. Fractionation of this extract led to the isolation of seven dibenzo-α-pyrones (1-7),

The aim of this study was to introduce novel Sn, Cu, Hg, and Ag nanopowders (NPs) and a composite nanopowder (NP) synthesized using Salvia miltiorrhiza Bunge (SM) root extract as a reducing and capping agent to improve the antibacterial property of dental filling materials. All of the NPs obtained

OBJECTIVE To synthesize two heterologous endochitinases in Escherichia coli and demonstrate their potential for applied use in generating antibacterial chitin-derived oligosaccharides (OGS). RESULTS Heterologous endochitinase genes, chiA Nima and chiA74, were expressed in E. coli. Endochitinases
