The antioxidant activity of the plant extracts was determined by a spectrophotometric method based on the ability of an antioxidant to reduce a ferric (Fe 3+) ion from the Fe 3+ -TPTZ complex to the ferrous (Fe 2+) ion from a Fe 2+ -tripyridyltriazine complex through the donation of an electron at low pH 32. The recent studies have investigated that the antioxidant effect of plant products is mainly attributed to phenolic compounds such as flavonoids, phenolic acids, tannins etc. Antioxidant properties have been attributed to the essential oils but a great diversity of results has been reported, mainly attributed to the chemical composition of the essential oils and the diversity of tests used. Medicinal plants have been known to treat simple to life-threatening diseases in different communities of Nepal for many years. Peucedanum ostruthium (L.) W. D. J. Koch (Apiaceae) is a worldwide perennial herb native to the mountains of central Southern Europe. Leontopodium alpinum Cass. At 30 days after . Five plant species namely, Phyllanthus acidus, Piper aduncum, Pandanus amaryllifolius, Macaranga peltata and Acacia mangium were analysed for their effective in-vitro bioactivity. In present study, we carried out a systematic record of the relative antioxidant activity in selected Iranian medicinal plant species' extracts. Extracts were prepared by maceration of each plant material in chloroform: methanol (C: M; 1:1 v/v) mixture. hence, the aim of this work was to study the antioxidant activity of extracts obtained from the following medicinal plants: caraway ( carum carvi l.), coltsfoot ( tussilago farfara l.), dandelion ( taraxacum officinale f.h.wigg. The antioxidant activity was determined by measuring the radical scavenging effects against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and ferric-reducing (FRAP) capacity. INTRODUCTION Plants, as the source of medicine, have been playing an important role in the health services . medicinal plants is more effective and safe remedy. Medicinal plants are potential sources of new drugs to improve the treatment of diseases whose treatment is associated to anti-oxidative agents. One hundred and twenty six Vietnamese traditional herbals belonging to 59 families were screened for their free radical (DPPH) scavenging activity and inhibitory effect on lipid peroxidation. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. In fact, several in vitro assays for the determination of antioxidant ability have been used. Here, the anticancer, antimicrobial and antioxidant activities of ten antioxidant-rich Cameroonian medicinal plants and of some of their isolated compounds are evaluated.The plant extracts were prepared by maceration in organic solvents. Among the diverse Anacardium plants' bioactive effects, their antioxidant, antimicrobial, and anticancer activities comprise those that have gained more attention. In the present investigation focused on qualitative, quantitative phytochemical and in vitro antioxidant activity of Cadaba fruticosa and Capparis . Synergistic antioxidant activity of selected medicinal plants in Brunei Darussalam and its application in developing fortified pasta. Considering the growing demand and the protected status of edelweiss in many countries, alternative methods of production have been developed, one of [.] Thus, the present article . Methods: In the current study ethanolic extract of Ocimum kilimandscharicum, Thymus serpyllum, Spilanthes acmella and their combination in equal ratio were used for their ability to counter oxidative stress. Peter O, Magiri E, Auma J, Magoma G, Imbuga M, Murilla G. Evaluation of in vivo antitrypanosomal activity of selected medicinal plant extracts. & Perr.. To commonly used medicinal plants with antioxidant activity known worldwide belong plants from several families, especially Lamiaceae (rosemary, sage, oregano, marjoram, basil, thyme, mints, balm), Apiaceae (cumin, fennel, caraway), and Zingiberaceae (turmeric, ginger). A number of secondary metabolites are present in its leaves, fruits, and other parts of the plant. The present study was conducted to evaluate preliminary phytochemical analysis and in vitro antioxidant activities of five plants (Olea europaea, Kigelia . Antioxidant compounds from plants can minimize the generation of free radicals [6,7] and alleviate diseases caused by oxidative stress [8,9]. All the tested plant extracts showed free radical scavenging activity. Antioxidant and cytotoxic activities and phytochemical screening of four Philippine medicinal plants. Antioxidant compounds from plants can minimize the generation of free radicals [6,7] and alleviate diseases caused by oxidative stress [8,9]. Antioxidant activities were evaluated by four assays: an antioxidant activity assay using Saccharomyces cerevisiae, a DPPH ((2, 2-diphenyl-1-picrylhydrazyl) assay to assess free radical scavenging . the antioxidant activities of ethanolic extracts obtained from medicinal plants (scutellaria baicalensis georgi, acanthopanax sessiliflorum seeman, pueraria lobata ohwi, portulaca oleracea linne, crataegus pinnatifida bunge var. We evaluated the potential of salicylic acid (SA) priming for overcoming the adverse effects of cadmium stress in Mentha arvensis L. plants. 2017), anti-inflammatory (Tavakoly et al. Fortification of pasta with the plant powder blends had resulted a significant increase of DPPH antioxidant activity, while successfully maintaining indistinguishable features as the control pasta . This study aims to analyze the phytochemicals as plant secondary metabolites, evaluate the antioxidant and antibacterial activities of Rubus ellipticus, Ziziphus mauritiana, Pyrus pashia, and Drynaria coronans extracts that are commonly being used as traditional medicine. The antioxidant hypothesis is however under discussion, and recent evidence suggested that its role has heavily been overestimated . Thus, Our systematic research showed that this three common plants of Sahara desert has diversified phytochemicals possessing satisfying extent of antimicrobial, antibiofilm and antioxidant activities.
2006;6:104-109. Thus, Our systematic research showed that this three common plants of Sahara desert has diversified phytochemicals possessing satisfying extent of antimicrobial, antibiofilm and antioxidant activities. A tocopherol graph was plotted by using-tocopherol as standard and the total antioxidant activity . It is a traditional medicinal plant characterized by its leaves that have a wide range of biological activities such as antioxidants, high blood pressure, anti-cancer and anti-microbial as it . In the present study, five medicinal plants were screened for their ovicidal activity againstHelicoverpaamigera ,Spodopteralitura ,Plutellaxylostella,Corcyracephalonica. Sl. The antioxidant activity of these plant The studies show the medicinal plants with emphasis on their antimicrobial, antioxidant properties of Foeniculum vulgare, Cuminum cyminum, Pegnum harmala, Rosmarinus officinalis and Chenopodium album. KEYWORD: Antioxidant activity, DPPH assay, Total antioxidant activity, Medicinal plant.

Conclusion: In sum, it can be said that the threeplant species showed potent antioxidant and analgesic activities. Results The . (edelweiss) is recognized as a frequent constituent of anti-aging skin care products, providing increased antioxidant and anti-inflammatory defense. . libor roots was practically inactive. The plants were collected from the district of Pithoragarh, Uttarakhand and extracted by soxhlet's apparataus using absolute ethanol (99.9%). Several reports are available on the antioxidant activity of medicinal plant extracts in India. In plants, phenolics can act as antioxidants by donating electrons to guaiacol-type peroxidases for the detoxification of H 2 O 2 produced under stress conditions 36. Anacardium plants have received increasing recognition due to its nutritional and biological properties. The hot water (WE) and ethanol extracts (EE) of sweet gale (Myrica gale L.), roseroot (Rhodiola rosea L.), sheep sorrel (Rumex acetosa L.), stinging nettles (Utrica dioica L.) and dandelion (Taraxacum officinale L.) were tested for total antioxidant capacity using ferric reducing .
