Bauhinia racemosa Lamk. (Caesalpiniaceae) is a small tree where bark and leaves are used extensively for the treatment of inflammation, headache, fever, malaria, skin infections, dysentery and diarrhea. The primary objective of this study was to evaluate the antioxidant, DNA cleavage and α-amylase inhibitory effects of the phenolic compounds: racemosol (BR-I), de-O-methyl racemosol (BR-II), 1,7...

Restrictions on the use of synthetic antioxidant such as butylated  hydroxyanisole  (BHA) and butylated  hydroxytoluene (BHT) are being imposed  because of  their carcinogecity. In this investigation  optimization  of phenolic extraction  process  frome  methanolic (80%)  extract (v/v) of  elaegnus  angustifolia  through  Response  Surface Methodology  by fulin cio- calteu is  performrd  for op...

the present research designed to evaluate the effects of foliar application of methyl jasmonate (meja), salicylic acid (sa) and potassium sulfate on improving fruit quality and photosynthesis system. ten treatments include: sa (0.3, 0.6 and 0.9 mm), meja (0.5, 1 and 2 mm), potassium sulfate (0.5, 1 and 1.5%) and distilled water (control) were sprayed on pomegranate trees 2 and 7 weeks after ful...

In the present study quantification of total phenolic content and evaluation in vitro antioxidant capability five different extracts Digera muricata was carried out by assays. DPPH radical, superoxide hydroxyl radical scavenging activity metal chelating were calculated compared with standard antioxidants. Reducing power extract also determined. All showed good free ability which gets enhanced i...

Total phenolic content and antioxidative properties of Taraxacum officinale leaves and flowers extract was studied. Extracts was made with different solvents: classical organic and surfactant solutions. The results showed that all examined extracts contain some polyphenols and have antioxidant potential against DPPH radical and reducing power (Fe3+ Fe2+). Leaf extracts made with organic solvent...

This research was performed to evaluate the effect of light intensity (310 and 630 μmol ms) on production and antioxidant activity of flavonoids and phenolic compounds from the leaves, stems and roots in three varieties of Labisia pumila Benth. The experiment was carried out base on randomized complete block design with a factorial arrangement. The results revealed that total phenolic and flavo...

The aim of this study was to optimize the extraction conditions for the extraction of phenolic compounds from Moringa oleifera leaves using response surface methodology (RSM). A user-defined design was applied to determine the effects of extraction time (min), extraction temperature ((o)C) and ethanol concentration (%), on total phenolic content (TPC) from Moringa oleifera leaves dried by three...
