Phytochemical Screening, Antioxidant and Antimicrobial Activity of Fabric Coated with Catharanthus Roseus Ethanolic Flowers Extract
<p>The aim of the present study was to evaluate the free radical scavenging and antimicrobial activity of fabric coated of the Catharanthus Roseus. Ethanol flowers extract. Free radical scavenging was determined by using 1, 1-diphenyl-2-picrylhydrazyl (DPPH), Reducing power, Hydroxyl radical scavenging assay and antimicrobial activity of Staphylococcus aureus, Escherichia coli and standard drug of Streptomycin using disc diffusion method. This inhibition was observed with the individual extracts and when they were used in lower concentrations with ineffective antibiotics. The present investigation clearly indicates that the Catharanthus Roseus possesses antioxidant properties and serve as free radical inhibitors or scavengers, acting possibly as primary antioxidants.</p><p>Keywords</p><p>Catharanthus Roseus, Fabric coated, DPPH, Staphylococcus aureus Escherichia coli, Streptomycin, Antioxidant,</p>

Occasional and constant exposure to dietary ethanol shortens the lifespan of worker honey bees
<p><span>Honey bees (<em>Apis mellifera</em>) are one of the most crucial pollinators, providing vital ecosystem services. Their development and functioning depend on essential nutrients and substances found in the environment. While collecting nectar as a vital carbohydrate source, bees routinely encounter low doses of ethanol from yeast fermentation. Yet, the effects of repeated ethanol exposure on bees' survival and physiology remain poorly understood. Here, we investigate the impacts of constant and occasional consumption of food spiked with 1% ethanol on honey bee mortality and alcohol dehydrogenase (ADH) activity. This ethanol concentration might be tentatively judged close to that in natural conditions. We conducted an experiment in which bees were exposed to three types of long-term diets: constant sugar solution (control group that simulated conditions of no access to ethanol), sugar solution spiked with ethanol every third day (that simulated occasional, infrequent exposure to ethanol) and daily ethanol consumption (simulating constant, routine exposure to ethanol). The results revealed that both constant and occasional ethanol consumption increased the mortality of bees, but only after several days. These mortality rates rose with the frequency of ethanol intake. The ADH activity remained similar in bees from all groups. Our findings indicate that exposure of bees to ethanol carries harmful effects that accumulate over time. Further research is needed to pinpoint the exact ethanol doses ingested with food and exposure frequency in bees in natural conditions.</span></p>
