Antioxidant and antibacterial activities of essential oil of Lippia sidoides against drug-resistant Staphylococcus aureus from food

Chemical composition, in vitro antioxidant and antibacterial activities of essential oil of Lippia sidoides (EOLS) and its major constituent was investigated. Chemical composition was analyzed in a gas chromatograph coupled to a mass spectrometer (GC/MS). Antioxidant activity (AA) was obtained using 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging assay. Antimicrobial activity was tested using disk-diffusion test...

Efficacy of lantana (Lantana camara) extract application against aphids (Brevicoryne brassicae) in rape (Brassica napus) over varied periods of time

Contact bioefficacy of lantana (Lantana camara L.) leaf extract (LLE) against rape aphids (Brevicoryne brassicae L.) in three rape (Brassica napus L.) seed brands at given time (hours) periods was explored. Samples of pounded young leaves mixed with distilled water (3 kg l-1, 2 kg l-1 and 1 kg l-1) were prepared. Dimethoate (7.5 ml 10 l-1) and distilled water were the positive and negative controls, respectively....

The antibacterial activity of bacterial endophytes isolated from Combretum molle

Although intense research has gone into the exploration of various Combretaceae species towards the discovery of therapeutic relevant compounds, their endophytes have never been explored as potential repositories of alternative sources of novel and medically beneficial equivalents. In the present study, five bacterial endophytes (Lysinibacillus, Staphylococcus, Enterobacter, Pseudomonas and Bacillus species) were...
