UV-B radiation may have either a positive or negative impact under the same conditions in wheat, depending on the type of secondary abiotic stressor: Cd or drought. Supplemental UV-B prevented the wilting and leaf rolling induced by PEG treatment. In contrast, combined UV-B and Cd treatment resulted in pronounced oxidative stress. The opposite effect of UV-B radiation in the case of drought or ...

Dalbergia latifolia Roxb. (Family: Fabaceae) is a traditional herb, contain latinone and dalcriodain flavonoid having excellence medicinal value. Antioxidants play an important role for protecting the human body against damage by reactive free radicals. Methods: The antioxidant activities and phenolic contents of the ethanolic extract of the bark of Dalbergia latifolia was evaluated using in vi...

BACKGROUND Roots and leaves of the Cermela Hutan (Phyllanthus gomphocarpus Hook. F) plant were studied to determine antioxidant activity, phytochemical compounds, proportion of carbohydrate, crude protein, moisture, ash, fat, total phenolic content (TPC), and total flavonoid content (TFC). MATERIAL/METHODS Ten percent (10%) aqueous extract from both Phyllanthus gomphocarpus roots (PGR) and le...

The methanolic extract of the aerial part of Hedyotis corymbosa (L.) Lam. (Rubiaceae) was screened for antioxidant activity using 1,1-diphenyl-2-picryl hydroxyl (DPPH) quenching assay, 2,2'-azinobis-3-ethylbenzothiozoline-6-sulfonic acid (ABTS) cation decolorization test, ferric reducing power (FRP), scavenging capacity towards hydroxyl ion (OH*) radicals and nitric oxide (NO) radical inhibitio...

This work aimed at investigating the effects of three domestic cooking methods (roasting, sprouting and boiling) on phytochemical contents (phenolic content, flavonoid, fibre), and anti-obesity (weight loss, hypoglycemic effect, serum lipids) potential of soybean seeds in obese male rats. Ten different forms were implemented, combining hulled/unhulled and raw/cooked soybean seeds using a basal ...

An in vitro propagation system was developed to obtain shoot and root cultures from the Andean spice Sanicula graveolens (Apiaceae). Propagation of shoots, roots and plantlets was achieved by the temporary immersion system. The free radical scavenging effect of the methanol/water (7:3 v/v) extracts was determined by the discoloration of the 1,1-diphenyl-2-picrylhydrazyl radical (DPPH). Total ph...

Objective In this study, the levels and antioxidant activities of some secondary metabolites isolated from five pistachio (Pistacia vera) cultivars collected from four different geographical regions of Iran, were studied. Materials and Methods Total phenolic compounds levels were determined by Folin-Ciocalteu method. Total flavonoid content was determined as AlCl3 complex and expressed as mg ...

In Indonesia, Caesalpinia pulcherrima (L) Swartz is widely grown as an ornamental, whereas it is used as a medicinal herb in Mexico as an alternative treatment for dental and oral infections. At present, only fruit and root parts of the plant are used. The aim of this study was is evaluate the anti-microbial activity of ethanol extract of fruit, leaves, flowers and stems against microbes that c...

Objective: Propolis is a mixture of plant resins and bee secretions. This study is to evaluate the antioxidant and antimicrobial activity of stingless bee propolis (Tetragonulairidipennis), rearedfromPudukottai region of Tamilnadu, India and also to determine the total phenol and total flavonoid contents of the sample responsible for these properties. Methods: Stingless bee propolis was extract...

Lactuca serriola L. is a herbaceous species, used for human nutrition and medicinal purposes. The high antioxidant capacity of L. serriola indicates the possibility of enhancing its edible and health potential by increasing the flavonoid and phenolic contents. The present study aimed at enhancing the production of phenolics and flavonoids by hairy root cultures in Lactuca serriola transformed w...
