The current study focuses on the effect of Juniperus communis extract on the probiotic properties of lactic acid bacteria isolated from camel milk in the region of El Oued (Algeria). Chromatographic analysis by HPLC was carried out to detect the most important compounds extracted from the plant. The total phenolic and flavonoid contents were determined using the colorimetric procedures Folin–Ciocalteu and aluminum chloride. The probiotic properties were studied and evaluated in vivo with Juniperus communis extracts after isolating strains from camel's milk and identifying them using 16S rRNA gene sequencing. Chromatographic profiles of the phenolic compounds revealed that Juniperus communis extract is rich in quercetin. After conducting chemical analyses of polyphenols and flavonoids, the results demonstrated a high content of phenolic compounds in Juniperus communis extracts (polyphenols: 103.80 ± 0.30 mg GAE/g E. flavonoids: 15.85 ± 0.80 mg QE/g E). Sequencing and phylogenetic analysis showed that the isolates belong to Bacillus pumilus and Bacillus safensis strains. The combination of Juniperus communis and Bacillus safensis restored the healthy intestine wall structure and returned the blood biochemical parameters to normal values. It was found that the mixture enhanced anti‐inflammatory effectiveness by reducing erythrocyte sedimentation rate and C‐reactive protein values. Juniperus communis has a high polyphenol and flavonoid content which can have a considerable impact on Bacillus safensis probiotic properties. [ABSTRACT FROM AUTHOR]

This study aims to analyze indigenous knowledge of medicinal plants used by traditional healers to treat gastrointestinal disorders in the Oued Souf region. Data were collected through open-ended, semi-structured interviews. Various statistical indices, such as UV and ICF, were employed to evaluate quantitative data. The findings reveal that traditional healers utilize 47 medicinal plant species from 22 families for treating gastrointestinal disorders. Lamiaceae and Asteraceae emerge as the most dominant families, with 9 and 7 species, respectively. The most frequently used plant parts were leaves (35%), and the predominant method of preparation was infusion (55%). Among the most popular plants used by local healers were Artemisia herba alba Asso (UV = 0.85) and Juniperus communis (UV = 0.75). The study highlights the significant number and variety of medicinal plants employed by traditional healers to address digestive disorders. Consequently, this research can aid scientists in identifying plants with medicinal properties that may contribute to the development of new medications. [ABSTRACT FROM AUTHOR]
