“…The biologically active components in willow leaf extract, particularly polyphenols, have a negative impact by preventing harmful bacteria from adhering to the gut microbiota and boosting the growth of friendly bacteria. Also, the content of salicin in S. alba and S. purpurea extracts has a vital role in antimicrobial efficiency against Staphylococcus aureus ( Carpa et al, 2022 ). Phenolic substances are known for their immediate efficacy vs. harmful bacteria or reduction of the pathogens' ability to form bonds in the intestine ( Viveros et al, 2011 ).…”

Effect of Dietary Salicin Standardized Extract from Salix alba Bark on Oxidative Stress Biomarkers and Intestinal Microflora of Broiler Chickens Exposed to Heat Stress

et al. 2023

The implication of heat stress (HS) in the oxidative stress phenomenon and its related diseases in chickens has been widely reported. Salicin is a precursor for the synthesis of salicylic acid and aspirin obtained from the bark of Salix alba, with an undeniable anti-inflammatory effect. However, little attention has been paid to salicin’s antioxidant/oxidative stress-reducing effect compared to its well-known anti-inflammatory effect. The purpose of the study was to investigate the effect of dietary salicin standardized extract from Salix alba bark (SAB) on oxidative stress biomarkers and intestinal microflora of broiler chickens exposed to heat stress. In our study, chickens (14 days) were randomly allocated to three treatment groups (SAB0; SAB25; SAB50), each of which included five replicates with eight birds per replicate. Broilers were exposed to heat stress (32 ± 2 °C) between 14 and 42 days. The liver tissues were collected to analyze oxidative stress biomarkers (total antioxidant capacity, glutathione, catalase, superoxide dismutase). The intestinal content was collected and measurements of the intestinal microbial population were performed (E. coli, staphylococci, lactobacilli). Results indicated that liver malondialdehyde and protein carbonyls activity decreased (p < 0.05) in SAB50 treatment concomitantly with linearly increased total antioxidant capacity, and glutathione concentration. Dietary supplementation with SAB reduced (p < 0.05) the abundance of staphylococci and increased the number of lactobacilli. Taken together, SAB possesses an advantageous effect on liver oxidative status and the balance of intestinal microflora in broilers exposed to heat stress. These findings provide new insight into the potential use of salicin standardized extract from Salix alba bark for liver damage prevention and dysbiosis related to heat stress.

Salix species have been used in traditional medicine to treat fever and inflammation. However, there is no reported information on the antibacterial activities of S. aurita and S. pyrolifolia, and little is known about the phytochemistry of S. aurita. In this study, winter-dormant twig extracts of S. aurita, S. caprea, and S. pyrolifolia were screened for their antibacterial activities against Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus, and Escherichia coli. The antibacterial effects were evaluated using agar diffusion and turbidimetric microplate methods. Time-kill effects were measured using the microplate optical density (OD620) method. UPLC-PDA-QTOF/MS analysis was conducted to identify the polyphenols present in a methanol extract of S. aurita. The antibacterial results show that methanol and hot and cold water twig extracts of S. aurita, S. caprea, and S. pyrolifolia have significant antibacterial effects against P. aeruginosa, S. aureus, and B. cereus with the diameters of the inhibition zones (IZDs) ranging from 16.17 to 30.0 mm and the MICs between 1250 and 2500 µg/mL. Only the cold water extract of S. caprea was moderately active against E. coli. Proanthocyanidins, procyanidin B1 (m/z 577), and procyanidin C1 (m/z 865) were identified as the major polyphenols present in the methanol extract of S. aurita twigs for the first time. Additionally, salicin-7-sulfate was present in S. aurita twigs. Procyanidin B-1, taxifolin, trans-p-hydroxycinnamic acid, and catechin showed growth inhibitory activity against B. cereus with a MIC value of 250 µg/mL.
