Objective(s): This study considered the combination of chitosan nanoparticles with antioxidant-antibacterial fraction extracted from Lactobacillus casei and investigation of possible increasing of antibacterial activity of the fraction in hybrid nanoparticle and the effect of the fraction on the stability of chitosan nanoparticles. Methods: Extra...

BACKGROUND The plant, Chrysophyllum albidum is indigenous to Nigeria and its stem-bark has wide application in traditional medicine for the treatment of infections and oxidative stress related diseases. The aim of the study was to isolate the chemical constituents responsible for the antioxidant and antibacterial activity from the stem-bark of the plant in order to justify some of its ethnomedi...

In order to validate the Bumelia sartorum Mart., Sapotaceae, traditional use for infection diseases, this study evaluates the antibacterial activity of the stem bark fractions against methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) Staphylococcus aureus strains by using the agar dilution method and reported as MIC (minimal inhibitory concentration). In addition, the DPPH scavengin...

The petroleum ether and chloroform fractions of ethanol extract of leaf and stem from the plant Passiflora edulis (Fam: Passifloraceae) was subjected to antioxidant, antibacterial and cytotoxic activity. All the fractions showed potent antioxidant activity, of which the chloroform and petroleum ether fraction of stem demonstrated the strongest antioxidant activity with the IC50 value of 51.28 μ...

Ethanol extract and fractions obtained from leaves of Solanum lycocarpum were examined in order to determine their phenolic composition, antioxidant, antibacterial, anti-inflammatory, and cytotoxic potential. High performance liquid chromatography coupled with DAD analysis indicated that the flavonoids apigenin and kaempferol were the main phenolic compounds present in dichloromethane and ethyl...

Introduction: In this study, Antibacterial and antioxidant activities of the essential oil and methanolic extract of the endemic plant, Zataria multiflora Boiss. have been studied. Method: The antioxidant potential of the samples was evaluated using two separate methods of inhibition of free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ammonium thiocyanate systems. Antibacterial activity wa...

This study was carried out to evaluate the Brine shrimp lethality (cytotoxicity), antiglycation, phytotoxicity, antiplatelet, antifungal, and antibacterial activities of Ajuga bracteosa. The n-hexane fraction of Ajuga bracteosa was investigated for various biological activities in vitro. Hexane extract showed promising phytotoxicity (100%) at the highest dose only. Interestingly, n-hexane fract...

Geopropolis is a special type of propolis produced by stingless bees. Several pharmacological properties have been described for different types of geopropolis, but there have been no previous studies of the geopropolis from Melipona mondury. In this study, we investigated the antioxidant, antibacterial, and antiproliferative activities of M. mondury geopropolis, and determined its chemical pro...

The present study reports the phytochemical profiling, antimicrobial, antioxidant, and anticancer activities of Bauhinia variegata leaf extracts. The reducing sugar, anthraquinone, and saponins were observed in polar extracts, while terpenoids and alkaloids were present in nonpolar and ethanol extracts. Total flavonoid contents in various extracts were found in the range of 11-222.67 mg QE/g. I...
