Moutaouafiq Salma, Farah Abdellah, Alilou El Houssine, Benbrahim Kawtar, Bousta Dalila
Abstract
The purpose of this work is the comparative study of the bioactivity of three aromatic plants: Geranium (Pelagronium graveolens), bitter orange (Citrus aurantium) and lemon grass (Cymbopogon citrates) used by the local population for their medicinal virtues. Our samples came from an orchard in Agadir, Morocco. We examined their chemical components and their antibacterial activities against seven pathogens (Enterobacter aerogenesSalmonella typhiMicrococcus luteusKlebsiella pneumoniaeEscherichia coliBacillus subtilis and Staphylococcus aureus). The extraction was carried out by hydrodistillation. The analysis of the essential oil was done through GC/MS. The antimicrobial activity was examined using the disc diffusion method. C.citratus showed the highest yield 0.992% vs. 0.763% for P.graveolens and 0.313% for C. aurantium. The chemical analysis of C. citratus revealed the presence of three major constituents namely Geranial, Neral, and Geraniol. The essential oil extracted from C. aurantium is essentially composed of Limonene, Linalool, γ-elemene and α- terpineol. On the other hand, the essential oil of P. graveolens is mainly composed of alcohol Geraniol, Citronellol, Nerol, and Linalool. The biological tests have shown that all the essential oils are active against all the tested bacteria.

Engwa A G, Unaegbu M, Francis O H, Obiudu I K, Ugwu F C, Agbafor N K
Abstract
Reactive oxygen species generated from certain cellular processes cause tissue and cell damage and may alter the structure and functioning of proteins and nucleic acids. Endogenous antioxidant defence mechanisms involving certain enzymes as well as exogenous antioxidant from plants are capable of preventing such complications. This study investigated the in vitro and in vivo antioxidant activity of Murraya koenigii (curry leaf) extracts. Water and ethanol extracts of the leaf were obtained by soxhlet extraction.  In vitro antioxidant activity was by the ferric reducing power and hydrogen peroxide scavenging assays and the total flavonoid and flavonol levels determined. The in vivo activity was assessed using albino wistar rats which were treated with 100mg/kg of aqueous and ethanol leaf extracts and ascorbic acid as positive control for six consecutive days after which a single dose (2.5mL/kg body) of CCl4 was administered except for the normal control group 24hrs later. The animals were sacrificed and the liver homogenate was used to assess the catalase activity and lipidic peroxidation. Aqueous and ethanol extracts showed ferric reducing activity and were concentration dependent. The hydrogen peroxide scavenging potential was very high at various concentrations for both extracts (between 81.2 to 99.9%) comparable to ascorbic acid.  Molondialdehyde (MDA) level (lipidic peroxidation) was significantly lower (p<0.05) in group 2 animals which received aqueous extract compared to group 1 (normal control) and group 4 (negative control). There was a significant difference (p<0.05) in the catalase activity of group 2 animals which received aqueous extract compared to the normal control. Acute toxicity was observed in group 5 animals administered ethanol extract. Flavonoid and flavonol were greater in the ethanol extract (625.33 and 835.04 g/g of rutin) than in the aqueous extract (449.33 and 100.33 g/g of rutin) respectively. These results suggest that Murraya koenigii (curry leaf) aqueous and ethanol extracts possess antioxidant activity due to high amounts of flavonoid and flavonol. This property may partly be responsible for the medicinal application of the plant.

Moradi M T, Karimi A, Alidadi S, Ghasemi-Dehkordi P, Ghaffari-goosheh M S
Abstract
The present study was mainly aimed to evaluate antioxidant activity and cytotoxicity of hydroalcoholic extract and three corresponding fractions of Quercus brantii acornA 70% ethyle alcohole extract of the plant were prepared and sequentially partitioned with n-hexane, chloroform, ethylacetate and n-butanol. The antioxidant potential of all these fractions was evaluated by the 2,2 diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity method.  Cytotoxic activity was tested against two normal cell lines (African green monkey kidney [Vero] and human dermal fibroblasts [HDFs]) by MTT assay. The results revealed that the n-butanol fraction exhibited the lowest IC50 value (6.5±0.6 μg/ml) with the highest antioxidant activity as compared to the other fractions. The IC50 values of the chloroform fraction, the n-butanol fraction, the crude extract, and the n-hexane fraction were found to be significant (p<0.05) as compared with butylated hydroxytoluene (BHT. The results of cytotoxicity showed that the chloroform fraction exhibited the highest cytotoxicity toward Vero and HDFs cell lines at concentration of 60.6±23 and 287.8±38 μg/ml, respectively. We conclude that at least, n-butanol fraction of this plant with high phytoconstituents and less toxicity could be a promising source of medicinally important natural compound. Our findings, therefore, suggest that overall the studied extract/fractions exhibit low cytotoxicity on normal cell lines.

Abstract
A Terminalia is a genus of Combretaceous plants extensively distributed in tropical and subtropical areas. Numerous species of this genus have been utilized for medicinal purposes because of their valuable phytoconstituents. This study aimed to compare between the phytoconstituents of the hydroalcoholic extract (HAE) of Terminalia bentzone (T. bentzoe) leaves as polar extract and its petroleum ether extract (PEE) as a nonpolar extract. Concerning this, total phenolics, flavonoids, proteins and carbohydrate content of the HAE were estimated. HPLC analysis of HAE revealed identification of nine phenolic acids, two flavonoids and one anthocyanin, they were gallic, ellagic, pyrogallol, catechin, chlorogenic acid, synergic acid, pyrocatechol, cinnamic acid, paraqumaric acid, caffeic acid, quercetin and rutin arranged according to the order of elution. Colum chromatographic separation of HAE resulted in the isolation of six compounds for the first time named: gallic acid1, ellagic2 methyl gallate3 catechin4, rutin5 and quercetin6. On the other hand, the PEE was fractionated to saponifiable and unsaponifiable fractions and both fractions were analysed by GC/MS. The GC/MS analysis of the saponifiable fraction revealed the identification of thirty-seven compounds as fatty acid methyl esters representing 83.51% of the total fraction, methyl hexadecanoate (39.98%) constitutes the major fatty acid methyl ester followed by methyl octadecanoate (6.62%). The analysis of the unsaponifiable fraction disclosed the presence of forty-nine compounds representing 72.32% of the total compounds, where butylated hydroxyl toluene (10.03%) constitutes the major compound. Both HAE and PEE were evaluated for their in vitro antioxidant potential by DPPH and β-carotene methods. The HAE superiors PEE in its antioxidant potentiality. Correspondingly, the HAE was subdued for further investigation embracing its in vivo antioxidant and antihyperlipidemic activities.

Abstract
Pistacia lentiscus belong to the family of Anacardiacea is widely used as medicinal plant in Algerian folk medicine for their powerful biological activities. The aim of this study is to quantify the different phenolic content from different parts of P. lentiscus (leaves, stems, fruits and roots), to evaluate their antioxidant activity, and to identify responsible molecules for this activity. The antioxidant activity of methanolic and selective extracts from all studied parts of P. lentiscus were evaluated by using DPPH free radical scavenging activity, reducing power, β-carotene bleaching assay and total antioxidant capacity (TAC). The phytochemical analysis of leaves, stems, fruits and roots extracts of P. lentiscus showed the presence of principal groups of secondary metabolites (flavonoids, tannins and anthocyanins). Leaves showed the highest value of phenolic compounds (216.289 ± 20.62 mg GAE/g DM), flavonoids (121.515± 9.171 mg CE/g DM) and condensed tannins (19.162 ± 0.436 mg CE/g DM). All extracts of leaves, stems and roots revealed a powerful total antioxidant capacity and high activities to scavenge DPPH radical, to reduce power and to inhibit the oxidation of β-carotene. Fruits exhibit the lowest values of antioxidant activity. Chemical composition realized by HPLC allowed the detection of gallic acid, ascorbic acid, r-coumaric acid, catechin and quercetin in the leaves of P. lentiscus, and for the first time: ferulic acid, vanillic acid and naringenin were also detected.

Abstract
Objective The aim of this study consisted in evaluating the antioxidant in vivo properties, anti-hemolytic and XOR inhibitory effect of Globularia alypum L. (GA) extracts. Methods: GA was submitted to extraction and fractionation to give crude (CrE), chloroformique (ChE), ethyle acetate (EAE) and aqueos (AqE) extracts. Total polyphenols contents of GA extracts were determined. The inhibitory activity of the extracts on the human oxidoreductase was evaluated. antioxidant activities of the CrE, EAE and AqE were tested by an in vivo assay in mice, the plasma ability to inhibit DPPH radical was measured. Results: EAE is the most rich in polyphenols (157.74 ± 5.27 mg GAE/mg of extract). GA Extracts inhibited XO in a concentration-dependent manner, the EAE showed the highest inhibitory properties on the XOR activity (IC50 = 0.083 ± 0.001 mg/ml), followed by CrE and ChE. The The CrE was found to exhibit the greatest scavenger activity with 48.41 ± 2.763%, followed by AqE and EAE (40.54± 7.51% and 41.79± 1.654%, respectively). Total antioxidant capacity of red blood cells was measured, from the kinetics of hemolysis obtained. The calculated HT50 reveal an extension of time for half hemolysis in all treated groups compared with the control group. CrE increase significantly HT50 (112.8± 2.427 min). The hemolysis is lagged, indicating that endogenous antioxidants in the erythrocytes can trap radicals to protect them against free-radical-induced hemolysis. Conclusions: Globularia alypum L. fractions have a strong inhibitory effect on xanthine oxidoreductase and also have a significant antihemolytic and antioxydant effect.

Barua C C, Patowary P, Bordoloi M J, Dutta P P, Dutta D J, Purkayastha A, Barua I C
Abstract
The study was conducted to evaluate the adaptogenic activity of hydroethanolic extract of Elsholtzia communis (Collett & Hemsl.) Diels. by estimation of neurobiological and biochemical changes associated with acute and chronic stress. Adult male Wistar rats were given forced swimming induced acute and chronic stress for 3 and 7 days, respectively. Hydroethanolic extract of Elsholtzia communis (EC) was orally administered at 100 (EC-100) and 200 (EC-200) mg/kg doses. For comparison, Panax ginseng (PG) extract (100 mg/kg, p.o.) was used as standard adaptogen. Plasma corticosterone, BDNF level, brain levels of lipid peroxides (LPO), superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH), cortical and hippocampal levels of monoamines viz. norepinephrine (NE), epinephrine (Ep) and dopamine (DA) were quantified for ascertaining biochemical changes accompanying stress. The results were further confirmed by the estimation of various proinflammatory cytokines (IL-6, IL-1β and TNF-α) in serum. As compared to vehicle treated stressed rats, the EC and PG treated significantly normalised chronic acute and chronic stress induced elevation of corticosterone and reduction of plasma BDNF; both doses (EC-100 and EC-200) stabilized the irregular oxidative status of the brain in stressed rats. EC treatment further suppressed the elevated levels of IL-6, IL-1β and TNF-α in stressed animals. The leaf of the plant is consumed by the local tribes in Nagaland, Arunachal Pradesh of northeast India, easily cultivated by farmers for its immense popularity. Hence, our study as an adpatogen has added one more medicinal property of this food plant, which can be successfully utilised as an adpatogen to combat adverse climatic condition prevailing in those areas.
