Background: Due to its flavoring and seasoning properties, Salvia officinalis has been widely used in the preparation of many foods. In folk medicine in Asia and Latin America, it has been used for the treatment of various types of disorders, including seizures, ulcers, rheumatism, inflammation, dizziness, and high blood sugar. Objective: The purpose of this study is to determine the chemical composition by HPLC/UV, antioxidant activity and lipid peroxidation; thus the, the anti-inflammatory effect of the ethanolic extract of Salvia officinalis (EES) on certain homeostatic parameters, inflammatory biomarkers and antioxidant status in Wistar rats subjected to inflammation induced by carrageenan. Method: Male rats (n = 24) were exposed to inflammation of the peritoneal by carrageenan (200 μL: 2\%) and treated for 5 days with ethanolic extract of Salvia officinalis (EES) in order to repair the damage caused by inflammation on homeostasis, TNF-α and PGE2. Results: The results of scavenging of DPPH and lipoperoxidation of the extract, showed an IC50 of 29.69 {\textpm} 1.32 and 46.17 {\textpm} 1.51 μg/mL, respectively. The identification of EEC by HPLC shows the presence of polyphenolic acids (salvianolic acid, rosmarinic acid, caffeic acid, ferulic acid) and many flavonoids (Cirsimaritin, Catechin, Acacetin, kaempferol, pinocembrine, quercetin). Salvia extract contains 221.08 {\textpm} 2.36 mg EAG/g and 80.54 {\textpm} 1.3 mg EQ/g dry extract. Compared to the control group, carrageenan induced a substantial decrease (P\<0.05) in antioxidant enzymes and a highly significant increase (P\<0.05) in homeostatic parameters (blood sugar, CRP and fibrinogen), biomarkers of inflammation (TNF-α and PGE2) and malondialdehyde levels. Conclusion: The administration of Salvia extract corrects this perturbation where there is an improvement in antioxidant enzymes and a decrease in biomarkers of inflammation. Salvia officinalis has been able to repair carrageenin-induced perturbations homeostasis and inflammation markers in Wistar rats.

Introduction: Lactic acid bacteria are used in the food industry and have restrictive criteria for probiotic potential. The most common growth media used for lactic acid bacteria is de Man, Rogosa, and Sharpe culture medium (MRS). Methods: In this study, three culture media were developed (date powder DP, date core DC and date core associated with lentils CL) based on locally available plant materials with a low market value to obtain a less expensive culture medium compared to the reference medium MRS for the growth of lactic acid bacteria. Four lactic strains were used (Lactobacillus acidophilus LbA-CECT4529, Lactobacillus plantarum LbP-CECT 748, Bifidobacterium animalis subsp lactis Bb12 and Bifidobacterium bifidum Bb 443). The growth and acidification kinetics of the tested strains were evaluated. The content sugar was determinate with HPLC. Results: All lactic bacteria were able to grow on all culture media, but the best results were obtained with MRS and DP media. No significant difference (p \<0.05) was observed between DP and MRS medium. The consumption of sugars and proteins in the DP medium was good with all tested bacteria (70.87 to 81.96\% and 71.42 to 80.90\%, respectively). After the analysis of sugar content of DP medium before and after fermentation with high-performance liquid chromatography (HPLC), fructose was the only sugar detected (45.28μg/ml {\textpm} 0.24). After fermentation, 83\% of fructose was consumed by Bb12. Conclusion: The present data allow us to conclude that date medium promotes the growth of lactic bacteria and can be considered as MRS standard medium substitute.

Introduction: Cardamom, also known as Elettaria cardamomum, a venerated perennial herb like the "Queen of Spices" belongs to the Zingiberaceae family. She holds various pharmacological activities due to its phytochemicals it contains such as; phenols, tannins, terpenoids, flavonoids, sterols. Methods: The study included the determination of the chemical composition of Elettaria cardamomum ethanolic extract (EEC) by HPLC/UV and evaluated their antimicrobial potential against ten pathogenic reference strains using two complementary techniques: the method of diffusion from solid discs and the determination of minimum inhibitory concentrations (MIC). Results: The results obtained from chemical identification of the EEC showed the presence of polyphenolic acids (rosmarinic acid, caffeic acid, ferulic acid, etc.) and many flavonoids (kaempferol, chrysin, galangin, pinocembrine, quercetin, etc.). The results of the antimicrobial effect showed that the extract reacted positively on almost all the microbial strains tested. The EEC extract significantly inhibited the growth of microbial strains, with a broader antimicrobial spectrum with extensive action with inhibitory zones between 8 and 33 mm in diameter. Thus, this extract revealed a dose-dependent antimicrobial activity on these microbial strains used. However, the inhibitory potential of the cardamom extract was variable compared to their MIC ranging from 6.25 to 12.5 mg of dry extract/mL. Therefore, the strains least susceptible to EEC are Bacillus subtilis, Escherichia coli, Aspergillus niger and Candida albicans. Conclusion: This activity is due to the phenolic compounds produced by the EEC extract. This extract can be used for the development of plant medicines against microbial infections and fungal infestations.
