The present work includes extraction of Betula alnoides bark using ethyl acetate as a solvent, preliminary phytochemical test, quantification of phytochemicals and quantification of lupeol in Betula alnoides by High Performance Thin Layer Chromatography (HPTLC) instrument along with the assessment of the antimicrobial potential of Ethyl Acetate Extract (EAE). The marc obtained after defatting of the coarsely powdered crude drug in Petroleum ether (60-80) was extracted using ethyl acetate. Afterward, preliminary phytochemical tests were done. For High Performance Thin Layer Chromatography (HPTLC), the solvent used was n-hexane: ethyl acetate (8:2 v/v) and scanning was performed at wavelength 254 nm. EAE was screened for antimicrobial potential. The extraction yield was 3.45% w/w. The result of the phytochemical analysis confirmed the presence of some important phytochemicals in EAE. A clear and resolved peak of lupeol was observed at Rf 0.61. The developed method was validated as per ICH guidelines. The concentration (%) of the marker compound (lupeol) was found to be 0.0168. Disk diffusion method using Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis as bacterial strains and Candida albicans, Aspergillus flavus and Epidermophyton floccosum as fungal strains against ciprofloxacin (for antibacterial activity) and fluconazole (for antifungal activity) as standard drugs was employed. The finding suggested that EAE possess significant antibacterial and antifungal activity when comparison was made with standard drugs. The proposed elucidated mechanism behind this action may be due to the presence of triterpenoids in EAE.

This study aims to investigate the biological activities of endemic plant Anabasis aretioïdes harvested in eastern Morocco. Various extracts were prepared from aerial part by aqueous and organic extraction using a Soxhlet and cold maceration. Preliminary phytochemical analysis was carried out on the powder and on the different extracts by standard phytochemical tests, and was confirmed by a quantitative analysis based on the determination of total polyphenols and cathechic tannins. Antioxidant activity was evaluated in vitro by five methods: H2O2, DPPH, ABTS, FRAP, and RP, and the antibacterial activity was carried out by disc diffusion method and the determination of MIC and MBC. Phytochemical screening revealed the presence of cathechic tannins, saponins, and sterols and quantitative analysis showed that Ethyl acetate extract presented the high level of phenolic and cathechic tannins contents (46.79 ± 0.75 µg GAE/mg E and 46.46 ± 0.67 µg CE/mg E). A highest hydrogen peroxide activity was observed in aqueous macerated extract (7.84 ± 0.44%) and the macerated methanol extract has the highest rates for the other four antioxidant activity tests: It was able to reduce DPPH with an IC50 of 52.91 ± 0.24 µg/ml, the highest ABTS•+ radical scavenging capacity (48.99 ± 1.316 µg TE/mg E), it showed also the highest antioxidant activity by the FRAP and reducing power test (99.73 ± 3.570 µg TE/mg E and 72.176 ± 0.540 µg AAE/mg E). Antibacterial screening showed that the maximum zone of inhibition was noted for ethyl acetate extract against Staphylococcus aureus (13.5 mm). The lowest MIC value was obtained with methanolic and macerated methanolic extracts against Protéus mirabilis strain (MIC = 3.125 mg/ml). Principal component analysis showed that the four methods ABTS, DPPH, FRAP, and RP are highly correlated and a correlation between the antioxidant activity and the total phenolic contents of the extracts indicated that phenolic compounds were the dominant contributors to the antioxidant activity of the plant.

Fungal food spoilage plays a key role in the deterioration of food products, and finding a suitable natural preservative can solve this problem. Therefore, antifungal activity of green mandarin (Citrus reticulata) essential oil (GMEO) in the vapor phase against the growth of Penicillium (P.) expansum and P. chrysogenum inoculated on wheat bread (in situ experiment) was investigated in the current research. The volatile compounds of the GMEO were analyzed by a gas chromatograph coupled to a mass spectrometer (GC–MS), and its antioxidant activity was determined by testing free radical-scavenging capacity (DPPH assay). Moreover, the disc diffusion method was used to analyze the antifungal activity of GMEO in in vitro conditions. The results demonstrate that the Citrus reticulata EO consisted of α-limonene as the most abundant component (71.5%), followed by γ-terpinene (13.9%), and β-pinene (3.5%), and it displayed the weak antioxidant activity with the value of inhibition 5.6 ±0.7%, which corresponds to 103.0 ±6.4 µg TEAC.mL-1. The findings from the GMEO antifungal activity determination revealed that values for the inhibition zone with disc diffusion method ranged from 0.00 ±0.00 (no antifungal effectiveness) to 5.67 ±0.58 mm (moderate antifungal activity). Finally, exposure of Penicillium strains growing on bread to GMEO in vapor phase led to the finding that 250 μL.L-1 of GMEO exhibited the lowest value for mycelial growth inhibition (MGI) of P. expansum (-51.37 ±3.01%) whose negative value reflects even supportive effect of the EO on the microscopic fungus growth. On the other hand, GMEO at this concentration (250 μL.L-1) resulted in the strongest inhibitory action (MGI: 54.15 ±1.15%) against growth of P. chrysogenum. Based on the findings it can be concluded that GMEO in the vapor phase is not an effective antifungal agent against the growth of P. expansum inoculated on bread; however, its antifungal potential manifested against P. chrysogenum suggests GMEO to be an appropriate alternative to the use of chemical inhibitors for bread preservation.

Introduction: The effectiveness of antimicrobial solutions employed in dental prosthesis decontamination is still uncertain. Aim: To evaluate the antifungal activity of cleaners used in the decontamination of dental prostheses on the growth of Candida albicans. Material and method: The evaluated products were: Corega Tabs(r) (S1), Sodium Hypochlorite 1% (S2), Sodium Bicarbonate 1% (S3), Hydrogen Peroxide 1% (S4), Chlorhexidine Digluconate 0.12% - Periogard (r) (S5), Mouthrinse based on essential oils - Listerine(r) (S6), essential oil from Rosmarinus officinalis (rosemary) at concentrations of 1% (S7) and 2% (S8). The antifungal activity of the products was evaluated by agar diffusion technique and the determination of microbial death curve of samples of C. albicans (ATCC 90028) in concentration 1.5 × 106 CFU/mL. The tests were performed in triplicate and statistical analysis was made by ANOVA Two-Way and Tukey tests, with the confidence level of 95%. Result: The average of the zones of inhibition growth, in millimeters, obtained for the products were: 0.0 (S1), 44.7 (S2), 0.0 (S3), 21.6 (S4), 10.0 (S5), 6.1 (S6), 0.0 (S7) and 2.4 (S8). Considering the determination of microbial death curve, all products showed a statistical difference (p<0.01) from control (0.85% sodium chloride) and S3 groups. Fungal growth less than 2×104 CFU/mL and an accentuation of the microbial death curve were observed after 30 minutes, with exception for S3 and control groups. Conclusion: The studied compounds, with the exception of Sodium Bicarbonate, have antifungal effect against C. albicans, which contribute for dental prostheses hygiene.
