Methanolic Extracts

Cuminum cyminum (in arabic: Kemoun) is an important source of therapeutic, cosmetic, bio-food and technological agents. Ancient civilizations used this plant for therapeutic purposes. Extracts from this plant are nowadays strongly used in the industrial and research fields, particularly for the medicinal, pharmacological and cosmetological purposes. Bioactive molecules extracted from Cuminum cyminum may express biocidal activities and prove to be good candidates for new antioxidants. The objective of the present work is to evaluate the biological properties of this plant, including antibacterial and antioxidant effects. The seeds of cumin are harvested at the wilaya of Biskra, and stored in a dry place until their use. They were identified at Hassiba Benbouali University of Chlef. Essential oil is obtained by hydro-distillation using a Clivenger type device (AFNOR, 2000). The obtained sample is stored in sealed bottles at low temperature (4°C) and away from light. The antibacterial effect is assessed by the disc method. The minimum inhibitory concentration (MIC) is determined by standard methods. The antioxidant activity is evaluated by the DPPH free radical trapping method of the methanolic extracts. The essential oil of C. cyminum shows a better activity against Gram+ strains compared to Gram- strains. The determination of MICs leads to the conclusion that its activity can be triggered at a very low concentration. The reaction with DPPH gives an interesting IC50. This testifies to the ability of this essential oil to reduce free radicals. Thanks to the antibacterial activities that we have highlighted, cumin can be considered as a palliative that could replace certain antibiotics. Moreover, its antioxidant activity allows us to use it as a natural food additive.

The Impact

The impact of two extraction solvents on the phenolic composition, antioxidant, and enzymes inhibitory and antimicrobial activities of two parts (leaves and stem bark) of P. kotschyi was studied. Two different LC-DAD-MSn approaches were used to identify and quantify the bioactive compounds in the different extracts. A total of thirty-two compounds were quantified, being the procyanidin the most abundant in stem bark while catechin and flavonoids are most abundant in leaves. Overall, the stem bark extraction using methanol showed higher amounts of total phenolic (131.83 ± 1.81 mg GAE/g) and flavanol (14.14 ± 0.11 mg CE/g) while the leaves extraction using water exhibited stronger levels of total flavonoid (44.95 ± 0.38 mg RE/g) and phenolic acid (63.58 ± 2.00 mg CAE/g). As regards the antioxidant assays, methanol stem bark extracts were characterized by the highest antioxidant activities (DPPH: 1.94 ± 0.01 mmol TE/g, ABTS: 3.31 ± 0.01 mmol TE/g, FRAP: 2.86 ± 0.02 mmol TE/g, CUPRAC: 5.09 ± 0.08 mmol TE/g, phosphomolybdenum: 5.16 ± 0.23 mmol TE/g and metal chelating: 17.12 ± 0.46 mg EDTAE/g). In addition, the methanolic extracts of stem bark had highest impact on acetylcholinesterase (2.54 mg GALAE/g), butyrylcholinesterase (5.48 mg GALAE/g). In contrast, the methanolic extracts of leaves was potent against tyrosinase (77.39 ± 0.21 mg KAE/g) and α-glucosidase (0.97 ± 0.01 mmol ACAE/g), while a higher anti-α–amylase (0.97 ± 0.01 mmol ACAE/g) was observed for water extracts of the same part. All of the tested extracts showed inhibitory effects on elastase, except methanolic leaves extracts. Additionally, the extracts exhibited appreciable antifungal toward A. ochraceus, A. fumigatus, P. ochrochloron, T. viride, and P. funiculosum and promising antibacterial activity against M. flavus, S. aureus, L. monocytogenes, E. coli, P. aeruginosa, E. cloacae, and S. typhimurium. Taken together, the outcomes demonstrated P. kotschyi as a novel source of bioactive molecules of interest with an evident therapeutic value.

Some of appropriate actions that could be initiated to taken to resolve the problem of these diseases are search for new antioxidant substances isolated from plants. The aims of this study were to study the intraspecies variations of A. verticillata and C. caeruleus essential oils from 8 locations using statistical analysis, the in vitro antioxidant properties of collective essential oils and in combinations. Materials and Methods: The essential oils were analyzed by GC and GC-MS. The intraspecies variations of the essential oil compositions were discussed using principal component analysis (PCA) and cluster analysis (CA). The antioxidant properties were evaluated DPPH-radical scavenging activity and β-carotene bleaching test. Results: The main components of Ammoides verticillata collective essential oil (Coll EO) were thymol (30.5%), carvacrol (23.2%), p-cymene (13.1%), limonene (12.5%) and terpinene-4-ol (12.3%). While roots of Carthamus caeruleus essential oil were dominated by carline oxide (86.2%). The chemical variability allowed the discrimination of two main Groups for both Coll EOs. A direct correlation between the altitudes, climate and the chemical compositions was evidenced. Ammoides verticulata and Carthamus caeruleus Coll Eos showed good antioxidant activity. In binary mixture, the interaction both Coll Eos and between oils rich of thymol and/or carvacrol with carlina oxide produced the best synergistic effects, compared to individual essential oils and the synthetic antioxidant (BHT). Conclusion: Ammoides verticillata and Carthamus caeruleus essential oil blends can be used as a natural food preservative and alternative to chemical antioxidants.

The propolis, an extremely complex resinous material, exhibits valuable pharmacological and biological properties, mainly attributed to the presence of polyphenols. The composition of propolis depends on time, vegetation, and the area of collection. Total flavonoid and polyphenol contents of aqueous extracts of propolis samples from different areas of Algeria, determined by using aluminum chloride and Folin–Ciocalteu colorimetric methods, were in the range of 3.047 ± 0.004–5.273 ± 0.013 mg/g and 96.833 ± 0.027–458.833 ± 0.0005 mg/g crude extract of propolis, respectively. This study examined the antioxidant and antimicrobial activities of propolis. Aqueous extracts of propolis were obtained in order to evaluate their antioxidant activities by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, β-carotene and electrochemical assays. All tested propolis samples had relatively strong antioxidant activities, which were also correlated with the total polyphenol and flavonoid content present. The percentage of inhibition of lipid peroxidation of linoleic acid emulsion during 24 h varied between 86.04 ± 0.42 and 90.60 ± 3.77% among the tested samples. The highest DPPH radical scavenging activity was observed by ABAL (Ain Abassa Aqueous Extract) with IC50 = 8.49 ± 5.07 10−5 μg/ml, and the lowest was observed by SAL (Setif Aqueous Extract) with IC50 of 21.16 ± 0.0001 μg/ml. The most important antibacterial activity was obtained with Ain Abassa extract; the zones of inhibition obtained for this excerpt vary from 15.22 to 15.5 mm. Followed by the Setif extract with areas of 12.33 to 12.75 mm, the Tizi-Ouzou extract with areas of 10.11 to 11.11 mm. This study will bring an innovation for further studies with regard to the antioxidant and antibacterial properties of the aqueous extracts of propolis. This study corroborates that Algerian propolis is a rich source of natural antioxidants, properties which could be used in the prevention of different diseases, both in humans and in animals.

Cocoa pod extract ((Theobroma cacao L.) has antioxidant and antimicrobial activity that has the potential as a natural food preservative. However, in its use the cocoa fruit skin extract has a disadvantage because the short shelf time and its application to food are limited, efforts are needed to prevent damage and extend shelf life, one of the efforts that can be done is by encapsulating the extract.This study aims to determine the antibacterial activity and antioxidant encapsulation of cocoa peel extract, this study begins with the extraction of cocoa pods with ethanol solvent by comparing cocoa pods : solvent 1: 4 The skin of cacao cocoa fruit used is yellow harvested cocoa fruit, then chopped and dried to form flour.The sample is extracted by maceration with ethanol solvent Antioxidant test is done by DPPH method, while antibacterial test is carried out by the well diffusion method. This study used a completely randomized design method (CRD) with 5 treatments using a maltodextrin concentration of 20% (M1); 30% (M2); 40% (M3); 50% (M4) and 60% (M5). The results showed that the treatment gave the highest yield in the treatment of 60% maltodextrin concentration (M5), while the highest antioxidant activity was obtained in the treatment of 20% maltodextrin (M1) with IC50 75.98 µg / mL and the treatment with the lowest antioxidant activity was obtained at treatment of 60% maltodextrin concentration (M5) with IC50 value 114.89 µg / mL. While for the antimicrobial activity also obtained with the same results, namely treatment of 20% (M1) obtained a higher inhibition diameter compared to treatment at 30%; 40%; 50% and 60% for all types of bacteria. The inhibition diameter in the treatment of the concentration of maltodextrin 20% (M1) for E. coli bacteria is between 4.12 mm - 10.95 mm, Salmonella sp is 2.85 mm - 8 , 25 mm and for Staphylococcusaureus of 5.15 mm - 13.90 mm and the lowest inhibition diameter was obtained in the treatment of 60% maltodextrin concentration (M5) for E. coli bacteria of between 2.0 mm - 4.79 mm, Salmonella sp of 1.15 mm - 4.35 mm and for Staphylococcusaureusat 2.76 mm - 5.17 mm.This study concluded that the encapsulation of cocoa peel extract using 20% maltodextrin had the highest antioxidant and antimicrobial activity when compared with other treatments namely 30% concentration; 40%; 50% and 60% but for the treatment of 20% and 30% there is no difference. Ethanol extract of cocoa pods can be made in the form of encapsulates which are very likely to be used as natural preservatives.
