This study was conducted to determine the antioxidant and antimicrobial activities of methanol extract obtained from flower, leaf and root sections of endemic Adonis paryadrica (Boiss.) Kandemir & Aytaç stat. nova. naturally growing in the Turkish flora. The most efficient total phenolic compounds and flavonoid contents were obtained from leaf extract at 21.24 mg GAEs (gallic acid equivalent)/g dw and 54.97 mg REs (rutin equivalent)/g dw, respectively. Among the three different sections of this plant, leaf extracts showed the highest Cupric Reducing Antioxidant Power (CUPRAC) effect with 80.28 µmol TEs (trolox equivalent)/g dw. From the three different sections, the methanol extract of the leaf parts demonstrated strong antibacterial activity against Bacillus subtilis with a 16.1 mm zone diameter. These valuable and current findings from these precious plants, which constitute natural resources in terms of biodiversity, contribute innovative information to the literature on endemic plant species.

Medicinal plants have played an important influence in the development of human society; they were always at the forefront of all cultures and civilizations as a source of medicine. Medicinal plants are considered rich sources of secondary compounds, and many modern medications are derived from them. Hammada scoparia is a medicinal plant that belongs to the Chenopodiaceae family. It is currently found in North Africa (Morocco, Algeria, Libya, and Egypt) and has many medicinal properties used as folk medicine. The present research discusses the phytochemical components and biological activities of Hammada scoparia. The corresponding data were collected from various online databases, new research, and published resources. Different secondary compounds from the species have been documented, including flavonoids, tannins, alkaloids, terpenoids, and saponins. Pharmacological research has demonstrated that the major bioactives have antimicrobial, antioxidant, cytotoxic, and antimalarial activities and anticancer, reno-protective, and hepatoprotective effects. In conclusion, this study provides much information about the interests of vegetal species: Hammada scoparia.

In our work we were interested in the toxicity of fluorine on the various parameters of stress: chlorophyll, proteins, and antioxidant system in the lichen Xanthoria parietina (L.) Th. Fr., and for this purpose, lichen thalli were treated by sodium fluoride (NaF) at concentrations of 0, 0.5, 1.0, 5.0 and 10.0 mM, for time scale 0, 24, 48 and 96 h. The analysis results obtained revealed that all the parameters evaluated showed significant variations compared to those of the controls. From the analysis results obtained, it was noted that chlorophyll a (Ca), chlorophyll b (Cb) and total chlorophyll (Ca+b) decreased correlating with exposure times to NaF (r = -0.785, p < 0.001; r = -0.955, p < 0.001; r = -0.899, p < 0.001, respectively), with a significant increase of Ca/b ratio (p = 0.00572**) showing that Cb was more affected than Ca. However, hydrogen peroxide (H2O2) increased (r = 0.949, p < 0.001). In correlation with NaF concentrations, Glutathione (GSH) increased (r = 0.969, p < 0.001), while proteins decreased (r = -0.872, p < 0.001). Furthermore, results showed that catalase activity (CAT) increased correlating with increasing exposure time of X. parietina to increasing concentrations of NaF. Long-term exposure (48 h -96 h) caused a significant decrease in GSH content (p = 0.02*) followed by total destruction at time 96 h.
在我们的工作中，我们对氟对地衣叶绿素、蛋白质和抗氧化系统的各种胁迫参数的毒性感兴趣。Th。在0、0.5、1.0、5.0和10.0 mM浓度的氟化钠(NaF)处理地衣，时间尺度分别为0、24、48和96 h。分析结果表明，与对照组相比，所有参数均有显著差异。分析结果表明，叶绿素a (Ca)、叶绿素b (Cb)和总叶绿素(Ca+b)随NaF暴露时间的增加而降低(r = -0.785, p < 0.001);R = -0.955, p < 0.001;r = -0.899, p < 0.001)， Ca/b比值显著升高(p = 0.00572**)，表明Cb比Ca受影响更大，而过氧化氢(H2O2)升高(r = 0.949, p < 0.001)。与NaF浓度相关，谷胱甘肽(GSH)含量升高(r = 0.969, p < 0.001)，蛋白质含量降低(r = -0.872, p < 0.001)。此外，过氧化氢酶活性(CAT)随NaF浓度的增加而增加。长期暴露(48 h -96 h)导致谷胱甘肽含量显著降低(p = 0.02*)，随后在96 h发生完全破坏。

Sunflower oil is known for its therapeutic properties and culinary use. It is an important alimentary source of tocopherol and unsaturated fatty acids, and is used especially for wound healing. Studies on its antimicrobial potential, however, are lacking. The ozonation of oils of vegetable sources has been explored to enhance their therapeutic properties; however, studies that provide evidence of such benefits are still lacking. In the field of veterinary medicine, such data are even more scarce. In this study, the antimicrobial activity of ozonated sunflower oil was compared to that of non-ozonated oil, in an in vitro system, against strains of Staphylococcus aureus and Escherichia coli, isolated from intrauterine lavages of mares with endometritis. Tests were conducted using the minimum inhibitory concentration method. The ozonated oil was effective against S. aureus, whereas it was not against E. coli isolates. Our data open doors for discussion on the use of sunflower oil, with or without ozone treatment, for therapeutic purposes in veterinary medicine.

The aim of this study is to investigate genetic diversity in 48 einkorn (Triticum monococcum L. ssp. monococcum) landraces grown in agricultural areas of Bolu and Kastamonu. Therefore, variation in seven agro-morphological traits was investigated. Agro-morphological traits such as leaf weight (mg), coleoptile length (cm), root number (n), root length (cm), fresh root weight (mg), and dry root weight (mg) were examined by the coefficient of variation, ANOVA, and principal components analysis. The highest coefficient of variation (%) was observed in fresh root weight (FRW = 52.09%), while the lowest was in leaf weight (LW = 8.9%). Principal Component Analysis (PCA) was calculated as 76.93% variation in two main components. For molecular characterization, data obtained with iSSR primers were analyzed with the population genetics analysis program PopGene (ver. 1.32). According to PopGene results, the mean number of alleles, the mean number of effective alleles, and average genetic diversity values were calculated as na = 2, nea = 1.33, and h = 0.13, respectively. Among the agro-morphological traits, germination power, root number, and coleoptile length appeared to be reliable traits. The results show that the use of morphological characters alone for genetic diversity in populations is not sufficient to determine the difference between populations and their genetic structure.

Secondary metabolites are highly beneficial to human health and have commercial and industrial values. So, this research aimed to study the effects of exogenous salicylic acid (SA) and jasmonic acid (JA) on some secondary metabolites in purple coneflower. A field experiment as a randomized complete block design with three replications was conducted in Shahrood, Iran. Treatments were the factorial arrangement of 3 SA (0, 0.5, and 1 millimole) and 4 JA concentrations (0, 5, 20, and 50 micromole). The non-linear regression procedure was employed to quantify the relation of these materials with each other. The results indicated that the SA effect on all ten measured secondary metabolites changed with changing the JA levels as there was the interaction between these elicitors. On average, most (7 out of 11) of the combined SA_JA levels up-regulated the production of secondary metabolites as compared to the plants not sprayed with SA and JA. In terms of average response to elicitation with 11 combined SA_JA levels, they ranked from higher to lower as the guaiacol peroxidase, hydrogen proxide (H2O2), polyphenol oxidase, glutathione S-transferase, superoxide dismutase, NADPH oxidase, total phenolic content, phenylalanine ammonia-lyase, anthocyanin, and flavonoid. A few secondary metabolites appeared to have a biphasic relationship with each other. For instance, over lower and medium values of NADPH oxidase activity, anthocyanin content increased linearly with increasing NADPH oxidase activity; over higher values of NADPH oxidase activity, it showed a plateau state.

This study aimed at the investigation of in vitro biological activities (antioxidant and enzyme inhibition) and phytochemical composition of various extracts (ethanol maceration, aqueous infusion, and aqueous decoction) obtained from leaf organs of Helichrysum pallasii, which has been traditionally used as herbal tea and medicine in Eastern Anatolia. Experimental analysis showed that ethanol-based extract had higher total phenolic content (TPC: 103 mg GAE/gE) and showed superior antioxidant potentials (FRAP: 2205 μmol Fe2+/gE; ORAC: 2540 μmol Trolox Eq./gE; DPPH: IC50=0.58 mg/ml; CUPRAC: IC50=0.37 mg/ml; Phosphomolybdenum: IC50=1.34 mg/ml ve metal chelation: IC50=1.42 mg/ml) and enzyme inhibition (Acetylcholinesterase: IC50=1.49 mg/ml; Butyrylcholinesterase: IC50=1.98 mg/ml; Tyrosinase: IC50=0.68 mg/ml; Alpha-amylase: IC50=2.09 mg/ml; Alpha-glucosidase: IC50=0.51 mg/ml; and Pancreatic lipase: IC50=42.5 μg/ml) and contained higher amounts of phenolic (chlorogenic acid isomers and rutin) and fatty acid (palmitic, linoleic, and linolenic acids) compounds than traditional preparations (infusion and decoction). The current study's findings indicate that the leaves of the Helichrysum pallasii are a source of phytochemicals with strong antioxidant and enzyme inhibitory properties, implying that it could be a candidate for biotherapeutic agent research and development.

Ammi majus (L.) is commonly used to cure many diseases in Moroccan folk medicine, especially vitiligo. This research tries to evaluate the phytochemical constituents of two aqueous extracts (E1; Maceration; 48 h) and (E2: Infusion; 1h) and three organic fractions (F1: Cyclohexane), (F2: Ethyl acetate (EtOAc)) and (F3: Ethanolic (EtOH)) of A. majus (L.) seeds, as well as to study the antioxidant and analgesic activity of the species. Phytochemical analysis, antioxidant activity (DPPH, FRAP, ABTS, and TAC tests), and analgesic activity (writhing and tail immersion were induced by Acetic acid tests) were analyzed according to the literature. A quantitative phytochemical study indicate that the E1 had the highest content of total polyphenols (26.95 ± 0.53 mg GAE/g extract) and flavonoids (37.92 ± 0.46 mg QE/g extract), while F3 showed a promising flavonol content (24.26±0.08 mg QE/g extract). Tannins were found to be high in F1 (59.27 ± 0.16 mg CE/g extract) and F2 (57.65 ± 1.18 mg CE/g extract). Antioxidant results reveals that DPPH (IC50 = 179.68 ± 0.47 μg/mL) and FRAP (EC50 = 367.03 ± 0.12 μg/mL) show to E1 a high antioxidant activity. Regarding the analgesic activity of the different studied extracts, it was found that E1 has a high peripheral analgesic effect with 62.32 % and a high central analgesic potential throughout the experimentation at 500 mg/kg. Our studies demonstrated for the first time that A. majus seeds extracts have high antioxidant and analgesic activities through different analysis techniques.

The interest in medicinal plants encourages new research studies on plant extracts, as they are sources for treatments in medicine, agriculture, and veterinary. Calliandra tweedii is a native Brazilian species with broad use in folk medicine. This study aimed to examine the leaf crude extract (CE) of C. tweedii and its methanolic (MP) and hexane (HP) phases concerning total phenolic compounds (TPC), proanthocyanidins (PRO), and flavonoid profile, and correlate it to their antioxidant activity (DPPH and FRAP). CE and MP revealed high contents of TPC, PRO and high antioxidant activity (DPPH and FRAP) in relation to HP. Opposite, HP showed reduced antioxidant activity, according to the scarce phenolic constituents obtained from the partition. Five flavonols were detected by HPLC-UV-DAD, being quercitrin the major constituent. Also, one kaempferol derivate, and a series of three quercetin derivates were detected. Strong positive correlations were observed between DPPH, FRAP, and phenolic compounds. These discoveries are important to highlight the promising antioxidant activity of CE of C. tweedii, which could contribute to the expansion of popular herbal medicines and new drug discovery.

Thyme species produce a wide variety of phenolic compounds including tannins, phenolic acids, and flavonoids. Thymus atlanticus (T. atlanticus) and Thymus willdenowii (T. willdenowii) are important thyme species in the southeast of Morocco, with numerous biological properties. The polyphenolic extracts of these two thyme species were obtained using ethanol through Soxhlet apparatus. Antioxidant (DPPH, FRAP, and TAC methods), antihemolytic (2,2'-Azobis(2-amidinopropane) dihydrochloride (AAPH) induced hemolysis test), hypolipidemic (3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase activity inhibition test), and anti-inflammatory (protein denaturation inhibition) effects of extracts were carried out using in vitro methods. The results showed that the polyphenolic extracts of these two species revealed important amounts of phenolic compounds. The contents of flavonoids were significant in the two species, while the contents of tannins and anthocyanin were very low. T. atlanticus showed an important antioxidant activity and a considerable antihemolytic effect in AAPH-induced hemolysis test (IC50 = 0.29 mg/mL), while T. willdenowii showed an important anti-inflammatory activity in heat-induced protein denaturation test (IC50 = 1.61 mg/mL). Moreover, both extracts at a dose of 20 µg/mL showed an important in vitro hypolipidemic activity by inhibiting HMG-CoA reductase activity (T. willdenowii: 51.16 %; T. atlanticus: 62.83 %). In conclusion, T. willdenowii and T. atlanticus extracts have considerable antioxidant, antihemolytic, hypolipidemic, and anti-inflammatory effects. The richness of these species in polyphenols gives them a large specter of biological properties, making them a valuable source of natural bioactive compounds that could prevent or treat various diseases.
