Background: The ability of Centaurea maroccana (C. maroccana) and Centaurea acaulis (C. acaulis) to protect the kidney against CCl4-induced renal toxicity in male rats was investigated. Moreover, the total polyphenols and flavonoids amount and DPPH radical scavenging activity were estimated. Materials and Methods: Rats were pre-treated orally with C. maroccana and C. acaulis (200 mg/kg, daily for 2 weeks) along with CCl4 (1.5 ml/kg, three times a week for 2 weeks). At the end of the treatment procedure, all rats were sacrificed and renal protective effect of C. maroccana and C. acaulis was evaluated. Results: Administration of CCl4 alone significantly elevated kidney malondialdehyde, as well as serum creatinine, urea and uric acid. While kidney level of glutathione and catalase were reduced. These were accompanied by glomerular and tubular degenerations and necrosis. Pre-treatment with C. maroccana and C. acaulis ameliorated the above mentioned biochemical parameters and histological changes associated with nephrotoxicity induced by CCl4. Moreover, both studied extracts showed a noticeable total polyphenols and flavonoids amount and antioxidant activity in DPPH assays. Conclusion: From the results, it is suggested that C. maroccana and C. acaulis extract has the ability to protect kidney against oxidative damages, possibly through the antioxidant effects of their bioactive compounds.

Carum copticum L. comprises several relevant species for food, cosmetic, perfumery and pharmaceutical industries. GC/MS analysis of the enential oil of C. copticum revealed γ- terpinene as a major component of C. copticum, with its contribution of 33.85%. Essential oils (EOs) exhibited a significant antimicrobial activity against all tested microbial strains. In addition, the C. copticum oil demonstrated the highest DPPH radical scavenging activity. These results clearly show the antimicrobial and antioxidant effects of the plant essential oil.

Objective: Pistachio (Pistacia vera L.) hull are usually discarded as waste, which can lead to environmental pollution even a significant portion of polyphenols are often present in high concentrations in the outer parts of fruits. In this way, using a pistachio hull as a source of bioactive compounds will increase the value of pistachio production and offer valorization for a useless by-product. Methods: Different ethanol concentrations (5, 10, 25, 50, 75 and 95 %) were investigated and the extraction efficiency at extraction temperature from 20 to 90 °C and extraction times from 5 to 45 min was studied. The extraction yield of total polyphenols and proanthocyanidins from the pistachio hull and the antioxidant activity of the extract were evaluated. Results: The obtained results indicated relationships between the tested parameters and extraction yield. The maximum yield for total polyphenols and proanthocyanidins was obtained with 25% ethanol at 60 °C for 15 min (13.91±0.72 and 5.86±0.45 g/100g dry weight, respectively). DPPH radical scavenging activities of extracts were proved to have a linear relationship with the polyphenols yield in the extracts (R2=0.9907) with a maximum DPPH radical scavenging activity of 60.25%. Conclusion: These findings propose that pistachio hull extracts can be a valuable source of bioactive compounds.

The jaboticaba tree,Plinia trunciflora(O. Berg) Kausel, is popularly named “jabuticabeira” in Brazil and is used in folk medicine to treat diabetes and chronic inflammation of the tonsils, but studies evaluating the central effects of this species are limited. This study evaluated the antidepressant-like and antioxidant effects ofP. trunciflora(PT) aqueous extract, in which five different anthocyanins were identified. PT showed significant ferric-reduction power and DPPH radical scavenging activityin vitroand reduced lipid peroxidation bothin vitroandex vivo. At the behavioural level, PT (400 and 800 mg/kg, i.p.) dose-dependently reduced immobility time in the tail suspension test in Swiss male mice. The identification of bioactive compounds accompanied by thein vitroandex vivoantioxidant activity of PT suggests that these activities might be related to the antidepressant-like activity ofP. trunciflora.

Ficus dalhousie and Melissa parviflora Benth both plants have been used as Tranquiliser, Relaxants, Nervine tonic and Calming aids throughout the world. The present study was aimed to identify the antioxidant potential of the Ethyl acetate and Hydro alcoholic extract of these plants by in vitro methods. Anti-Alzheimer activity of the plant extract were screened by Acetylcholinesterase (AChE) inhibition and antioxidant by DPPH and Hydrogen oxide. The results of the assays were calculated by the percentage inhibition of these free radicals. In Acetylcholinesterase (AChE) assay inhibitory potentials of Ficus dalhousie exhibited 73.34 ± 1.12%, whereas in Melissa  arviflora it was 86.88± 2.12%. In DPPH radical scavenging assay the percentage inhibition was 77.87 ± 2.02% in Ficus dalhousie and 76.92± 1.32% in Melissa  arviflora. Hydrogen peroxide scavenging assay the percentage inhibition was 86.56 ± 1.05% in Ficus dalhousie and 80.75± 1.92% was in Melissa arviflora. In all the research assays, the extract showed a concentration dependent increase in free radical scavenging activity. The results revealed that the antioxidant effects of the plant extract might be due to the presence of phenol and flavonoid compounds.

This study compares the content of basic nutrients (proteins, fats, digestible carbohydrates, dietary fiber and ash), steviol glycosides, selected antioxidants (vitamin C, total polyphenols) and antioxidant activity in dried leaves of Stevia rebaudiana Bertoni cultivated in Poland, Paraguay and Brazil and available in the direct sale. The basic chemical composition was determined by standard AOAC (Association of Official Analytical Chemists) methods. Content of steviol glycosides was determined by the UHPLC-UV chromatographic method. Total polyphenols content was expressed as gallic acid equivalent (GAE) and catechins equivalent (CE). Antioxidant activity was measured as ABTS●+ free radical scavenging activity. Dried leaves of S. rebaudiana grown in Poland had significantly higher contents of dietary fiber, and lower protein and ash content, compared to those derived from Paraguay and Brazil. The former had, however, considerably higher contents of total steviol glycosides, stevioside and rebaudioside D, compared to the remaining two plants. In the Paraguay-derived dried leaves, the content of rebaudioside A, C, E and rubusoside was found to be significantly lower. Dried leaves of S. rebaudiana Bertoni, cultivated in Poland, contained substantially more vitamin C and a similar content of total polyphenols, compared to those from Brazil and Paraguay. The examined material from Brazil and Paraguay plantations showed similar antioxidant activity, while that obtained from Polish cultivation was characterized by a significantly lower value of this parameter.

The present study aimed to evaluate the potential of standardized methanolic extracts from seven Ficus deltoidea varieties in inhibiting the formation of AGEs, protein oxidation, and their antioxidant effects. The antiglycation activity was analyzed based on the inhibition of AGEs, fructosamine, and thiol groups level followed by the inhibition of protein carbonyl formation. The antioxidant activity (DPPH radical scavenging activity and reducing power assay) and total phenolic contents were evaluated. After 28 days of induction, all varieties of Ficus deltoidea extracts significantly restrained the formation of fluorescence AGEs by 4.55–5.14 fold. The extracts also reduced the fructosamine levels by 47.0–86.5%, increased the thiol group levels by 64.3–83.7%, and inhibited the formation of protein carbonyl by 1.36–1.76 fold. DPPH radical scavenging activity showed an IC50 value of 66.81–288.04 μg/ml and reducing power activity depicted at 0.02–0.24 μg/ml. The extent of phenolic compounds present in the extracts ranged from 70.90 to 299.78 mg·GAE/g. Apart from that, correlation studies between the activities were observed. This study revealed that seven varieties of Ficus deltoidea have the potential to inhibit AGEs formation and possess antioxidant activity that might be attributed to the presence of phenolic compounds.
