Abstract
BACKGROUND The aim of this research is to investigate the potential activity of Salvia officinalis and various hair samples responsible for secretion of essential oil. In Tunisia, biological activity of Salvia officinalis is poorly recorded. Salvia leaves contain various types of hairs (glandular and nonglandular). METHODS The investigation of different trichomes was carried out by Scanning Electron Microscope (SEM) apparatus. Antiradical potential was assessed using 2,2-Diphenyl-1-Picrylhydrazyl (DPPH) and Ferric Reducing Antioxidant Power (FRAP) assay. Antimicrobial activity was analysed using disc diffusion assay. The extracts of Salvia officinalis (SvOf), showed the following order of richness in phenolic contents: methanolic (70.76 mg GAE/g DW), aqueous (43.76 mg GAE/g DW) and infusion (9.42 mg GAE/g DW). The methanolic fraction records the highest levels of flavonoids (77 mg QE/g DW) compared with the aqueous extracts (33.19 mg EQ/g DW) and infusion (26.25 mg EQ/g DW). MESvOf showed higher value of free radical scavenging activity towards DPPH free radical and ferric reducing power. RESULTS The results revealed that the main bioactive constituents in the methanolic fractions of sage leaves generally exhibited higher antibacterial effects. Overall, sage phytocompounds constitute a promising approach for the treatment of infectious diseases. DISCUSSION Functional groups detected in S. officinalis by Fourier Transform Infrared Spectrophotometer (FT-IR) were mainly phenols, saccharides, amine and Aromatic (Ar-H). CONCLUSION Antiradical and antibacterial activities of Salvia officinalis are mainly due to phenolic content and other bioactive compounds. Non-glandular hairs are the most important trichomes in the Salvia leaves.

Abstract
Brachychiton populneus is one of the unexploited Tunisian plants, traditionally eaten as food and used for medicinal purposes. The present study aimed to investigate the phytochemical components of the seeds, leaves and flowers from B. populneus using three different solvents and to explore their antioxidant, anti-inflammatory and neuroprotective effects. Further, this study was focused on the identification of phenolic compounds from the most active extract. In vitro, all extracts showed strong antioxidant property by DPPH, ferrous ion chelating and lipid peroxidation-inhibiting assays, noticeable anti-inflammatory activity by protein denaturation and membrane stabilization methods and important neuroprotective effects by acetylcholinesterase inhibitory test. In vivo, B. populneus (50, 100 and 200 mg/kg, i.p.) showed significant dose-response anti-inflammatory effects against carrageenan-induced paw edema. With respect to the phenolic profile, the leaf methanol extract presented eight phenolic acids, one flavone and four flavonoids, with salvianolic acid B (820.3 mg/kg), caffeic acid (224.03 mg/kg), syringic acid (100.2 mg/kg) and trans-ferulic acid (60.02 mg/kg) as the major compounds. The results of the current study suggested that B. populneus could be a precious source of health-benefitting biomolecules and may be developed as new antioxidant, anti-inflammatory and AChE inhibitors.

Abstract
Nicotine is a potential inducer of oxidative stress, through which it can damage numerous biological molecules. Natural antioxidants that prevent or slow the progression and severity of nicotine toxicity may have a significant health impact. The purpose of this study, conducted on Wistar rats, was to evaluate the beneficial effects of green tea (Camellia sinensis) extract on nicotine treatment-induced damage on kidney. Our results showed that nicotine significantly (p < 0.01) increased serum and kidney malondialdehyde, the serum contents of urea, creatinine, and uric acid. In addition, nicotine intoxication significantly (p < 0.01) decreased the levels of vitamins E and C in serum and kidney tissue as well as the activities of superoxide dismutase, catalase, and glutathione peroxidase. Interestingly, animals that were pretreated with green tea, prior to nicotine administration, showed a significant nephroprotection, revealed by a significant reduction-induced oxidative damage for all tested markers. The nephroprotective activity of green tea is mediated, at least in part, by the antioxidant effect of its constituents.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lycium europaeum Linn. is widely used to treat the burning of the skin and well-known as a medicinal plant having various biological activities. AIMS OF THE STUDY The purpose of the present study is to characterize the polysaccharide from L. europaeum L. leaves (LEP) and to explore its antioxidant, anti-inflammatory and hepato-nephroprotective properties. MATERIALS AND METHODS The structural and functional characteristics of LEP were investigated using X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM), and FT-IR Spectroscopy. The antioxidant activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl and hydrogen peroxide scavenging assays. Hepato-renal effects were studied using CCl4 and cisplatin-induced liver and kidney injuries in mice, respectively. Anti-inflammatory activity was assessed on carrageenan-induced paw edema. RESULTS The LEP showed an interesting water-holding capacity and effective foaming and emulsifying properties. XRD analysis suggested that LEP form a semi-crystalline polymer with an amorphous structure. FT-IR profile showed the presence of pyranose ring in LEP. SEM and helix-coil transition analyses indicated that LEP had a lamellar structure with angular edges and didn't present a triple helical conformation in solution. In vitro, LEP indicated significant concentration-dependent antioxidant activity. In vivo, LEP treatment significantly reduced the effects of CCl4 intoxication on serum liver biomarkers (AST, ALT, LDH, and GGT) and the effect of cisplatin on serum renal biomarkers (urea, blood urea nitrogen, creatinine, and uric acid). Meanwhile, LEP diminishes significantly the effect of CCl4 and cisplatin on the level of lipid peroxidation in liver and kidney tissues, respectively. Additionally, the normal histological structure of liver and kidney was restored after treatment with the polysaccharide. LEP possessed a significant anti-inflammatory activity on acute inflammation induced by carrageenan in mice. CONCLUSION Overall, the findings of this study support the traditional use of L. europaeum L. This plant may also be used as a good agent for protection against inflammatory diseases and hepato-renal injuries in patients with cancer.

Abstract
Amaranthus spinosus has been consumed traditionally to prevent various diseases including abdominal pain. In this study, the phytochemical composition, antioxidant and analgesic activities of an ethyl acetate extract of A. spinosus leaves (ASEA) were evaluated. The ASEA had the highest concentrations of total phenols (462.2 mg GAE/g DW), condensed tannin (5.01 mg CE/g DW) and total flavonoid contents (30.07 mg CE/g DW) compared to the chloroform, n-hexane, n-butanol and water extracts. Similarly, ASEA showed the most effective total antioxidant activity (45.45 µg/mL), DPPH scavenging activity (27.32 µg/mL) and hydrogen peroxide scavenging activity (30.60 µg/mL). ASEA with the doses of 200-600 mg/kg (p.o.) clearly demonstrated antinociceptive effects by reducing acetic acid-induced abdominal contortions with a maximal inhibition of 79.57% at 600 mg/kg and increasing latencies of the hot-plate paw-licking response. The tested doses also significantly (p < 0.001) decreased the reaction time in the formalin test at the neurogenic and inflammatory phases. ASEA contained ten polyphenols with caffeic acid being the predominant polyphenol. Overall, this study gave evidence that A. spinosus is a new antioxidant and analgesic agent, and justified its traditional use for the treatment of pain.

Abstract
The aim of this study was to investigate the protective effect of Mentha spicata supplementation against nicotine-induced oxidative damage in the liver and erythrocytes of Wistar rats. Bioactive substances were determined by liquid chromatography – electrospray ionization – tandem mass spectrometry analysis. Animals were divided into 4 groups of 6 rats each: a normal control group, a nicotine-treated group (1 mg/kg), a group receiving M. spicata extract (100 mg/kg), and a group receiving both M. spicata extract (100 mg/kg) and nicotine (1 mg/kg). Many phenolic acids were identified in the M. spicata aqueous extract. After 2 months of treatment, nicotine induced an increase in the level of white blood cells and a marked decrease in erythrocytes, hemoglobin, and haematocrit. Aspartate transaminase, alanine transaminase, alkaline phosphatase, and lactate dehydrogenase activities were also found to be higher in nicotine-treated group than those of the control group. Furthermore, nicotine-treated rats exhibited oxidative stress, as evidenced by a decrease in antioxidant enzymes activities and an increase in lipid peroxidation level in liver and erythrocytes. Interestingly, the oral administration of M. spicata extract by nicotine-treated rats alleviated such disturbances. M. spicata contained bioactive compounds that possess important antioxidant potential and protected liver and erythrocytes against nicotine-induced damage.

Abstract
CONTEXT Opuntia ficus-indica (L.) Mill. (Castaceae) (cactus) is used in Tunisian medicine for the treatment of various diseases. OBJECTIVE This study determines phytochemical composition of cactus cladode extract (CCE). It also investigates antioxidant activity and hepatoprotective potential of CCE against lithium carbonate (Li2CO3)-induced liver injury in rats. MATERIALS AND METHODS Twenty-four Wistar male rats were divided into four groups of six each: a control group given distilled water (0.5 mL/100 g b.w.; i.p.), a group injected with Li2CO3 (25 mg/kg b.w.; i.p.; corresponding to 30% of the LD50) twice daily for 30 days, a group receiving only CCE at 100 mg/kg of b.w. for 60 days and then injected with distilled water during the last 30 days of CCE treatment, and a group receiving CCE and then injected with Li2CO3 during the last 30 days of CCE treatment. The bioactive components containing the CCE were identified using chemical assays. RESULTS Treatment with Li2CO3 caused a significant change of some haematological parameters including red blood cells (RBC), white blood cells (WBC), haemoglobin content (Hb), haematocrit (Ht) and mean corpuscular volume (VCM) compared to the control group. Moreover, significant increases in the levels of glucose, cholesterol, triglycerides and of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) activities were observed in the blood of Li2CO3-treated rats. Furthermore, exposure to Li2CO3 significantly increased the LPO level and decreased superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities in the hepatic tissues. CONCLUSION CCE possesses a significant hepatoprotective effect.

Abstract
Background Plant essential oils and phenolic compounds are widely used for their medicinal properties. Thus, the aim of this study is to evaluate the nutritional values, the chemical composition, antioxidant activity and anti-hemolytic effects of Pittosporum tobira seeds. Methods The aroma compounds were isolated using two methods (Headspace-solid phase microextraction (HS-SPME) and hydrodistillation (HD)) and analyzed by gas chromatography coupled with mass spectrometry (GC-MS). Bioactive phenolic compounds were identified by mean of high-performance liquid chromatography (HPLC-DAD). Reducing power, hydrogen peroxide (H2O2) scavenging and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays were used to investigate antioxidant activity. Anti-hemolytic activity was evaluated using H2O2-induced hemolysis of red blood cells (RBC). Results Oxygenated sesquiterpenes, sesquiterpene hydrocarbons and oxygenated monoterpenes were the most volatile fractions identified by HD and HS-SPME coupled to GC-MS but their quality and amount were quite different according to the extraction methodology. The main phenolic compounds identified by HPLC were caffeic acid, followed by cinnamic acid and gallic acid. P. tobira seeds essential oils showed significant antioxidant activity in DPPH (IC50 value = 1.5 mg/mL), H2O2 scavenging assay (IC50 value = 159.43 μg/mL) and reducing power test (IC50 value = 0.982 mg/mL) compared to methanolic extract. Moreover, the results revealed that the essential oil was able to protect RBC from hemolysis induced by H2O2. However, the methanolic extract had no effect on H2O2-induced hemolysis of RBC as compared to the essential oil and the standard vitamin C. Conclusions P. tobira may be used as a new natural source of antioxidant with therapeutic application in diseases caused by reactive oxygen species.

Abstract
In this study, the antioxidant, antinociceptive, hepatoprotective, nephroprotective properties and the bioactive composition of Lycium europaeum were investigated. Polyphenols and total tannin contents were measured by colorimetric methods The antioxidant activity in vitro was evaluated using the reducing power, 2,2-diphenyl-1-picrylhydrazyl radical and phosphomolybdenum assays. The hepatotoxicity and nephrotoxicity effects were studied using carbon tetrachloride (CCl4)-induced liver and renal injuries in mice. The analgesic activity was explored using the hot-plate and acetic acid tests in mice. Results showed that the methanol fraction of L. europaeum (LEM) had the highest level of total phenolic, total tannin, and flavonoid. HPLC-DAD analysis revealed the presence of twelve compounds among them caffeic acid was the major compound (140.18μg/g of extract). This fraction also showed the best antioxidant activity in vitro in the three used assays. In vivo, in the mice studies, CCl4 administration induced hepatotoxicity and nephrotoxicity by a significant rise in the levels of serum liver biomarkers (gamma glutamyl transferase, lactate dehydrogenase, and aminotransferases) and serum renal biomarkers (urea, creatinine, and uric acid). Similarly, levels of lipid peroxidation (MDA) in both tissues were found increased by CCl4 intoxication. Pretreatment with LEM and quercetin significantly restored the majority of these biological parameters to normal levels, as well as an improvement of histopathological changes. In addition, LEM showed an interesting analgesic activity. LEM decreased significantly the number of writhing induced by acetic acid and prolonged the reaction time in response to thermal stimulus in mice. Therefore, it was speculated that the obtained results highlighted the potential use of L. europaeum as a source of bioactive compounds with pharmacological advantages.

Abstract
Malva sylvestris is widely used in Mediterranean and European traditional medicine and ethnoveterinary for the treatment of various diseases. This study, carried out on male Wistar rats, evaluates the beneficial effects of Malva sylvestris extract upon lithium carbonate-induced damages in testes and heart. For this purpose, Malva sylvestris extract at a dose of 0.2g/kg was orally administrated, followed by 25mg/kg lithium carbonate (intraperitoneal injection, twice daily). Lithium carbonate treatment significantly (p<0.01) decreased the weight of testes, accessory sex organ and heart, sperm count and motility, and serum testosterone level. In addition, exposure to lithium carbonate significantly (p<0.01) increased lipid peroxidation level (LPO) and decreased superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities in testes and heart. Treatment with M. sylvestris extract affords substantial protection in testes and heart by altering all the parameters to near normal levels that were further confirmed by histological examination. The beneficial effect of M. Sylvestris extract in several organs could be attributed to the interaction of antioxidant components, such as complex polysaccharides, as confirmed by phytochemical analysis.

Abstract
Obesity is a one of the main global public health problems associated with chronic diseases such as coronary heart disease, diabetes and cancer. As a solution to obesity, we suggest Plantago albicans, which is a medicinal plant with several biological effects. This study assesses the possible anti-obesity protective properties of Plantago albicans in high fat diet-fed rats. 28 male Wistar rats were divided into 4 groups; a group which received normal diet (C), the second group was fed HDF diet (HDF), the third group was given normal diet supplemented with Plantago albicans (P.AL), and the fourth group received HDF supplemented with Plantago albicans (HDF+P.AL) (30mg/kg/day) for 7 weeks. Our results showed an increase in body weight of HDF rats by ∼16% as compared to the control group with an increase in the levels of total cholesterol (TC) as well as LDL-cholesterol, triglycerides (TG) in serum. Also, the concentration of TBARS increased in the liver and heart of HDF-fed rats as compared to the control group. The oral gavage of Plantago albicans extract to obese rats induced a reduction in their body weight, lipid accumulation in liver and heart tissue, compared to the high-fat diet control rats. The obtained results proved that the antioxidant potency of Plantago albicans extracts was correlated with their phenolic and flavonoid contents. The antioxidant capacity of the extract was evaluated by DPPH test (as EC50=250±2.12μg/mL) and FRAP tests (as EC50=27.77±0.14μg/mL). These results confirm the phytochemical and antioxidant impact of Plantago albicans extracts. Plantago albicans content was determined using validated HPLC methodology.
