Phytochemicals in red and purple bran rice have potential health benefit to humans. We determined the phytochemicals in brans of 32 red and purple global rice varieties. The description of the origin and physical traits of the whole grain (color, length, width, thickness and 100-kernel weight) of this germplasm collection are provided along with data of total flavonoid and total phenolic conten...

a pot experiment was conducted to evaluate the extract biochemical variations among 25 spearmint population. the experiment was a randomized complete design (rcd) with 25 treatments (population) and three replications. for this purpose, three rhizomes with 5 cm length were selected and planted in each pot. all pots were kept out side. the plant samples of all treatments were harvested at full f...

Many plants are used ethnomedicinally for the treatment of disease and restoration health. One these medicinal is Tithonia diversifolia . This study aims to determine phenolic flavonoid contents antioxidant activity using DPPH method from leaves T. Phenolic identification was carried out with FeCl 3 reagent; blackish green color formed indicates presence compounds. Identification a reagent betw...

BACKGROUND The five kashayams (kwaths - decoctions) Manjishtadi kashayam (MK), Rasna erandadi kashayam (REK), Sahacharadhi kashayam (SK), Maharasnadi (or Rasna dwiguna bhagam) kashayam (MRK) and Dhanwantharam kashayam (DK) are widely used in the management of diseases manifested due to vitiation of vata and vatarakta (mostly diseases of connective tissues, bones, joints and nervous system). Fre...

In the research it was examined the changes in total phenolic contents and seven major phenolic compounds (gallic acids, +(−) catechin, catechol, Chlorogenic acid, o-coumaric acid, rutin and quercetin) of two litchi cultivars (Purbi and Bedana) shoot tips and fruits (for zygotic embryos) collected in different months, in order to determine their effects on the explants browning during establish...

This study evaluated the efficacy of various organic solvents (80% acetone, 80% ethanol, 80% methanol) and distilled water for extracting antioxidant phenolic compounds from turmeric, curry leaf, torch ginger and lemon grass extracts. They were analyzed regarding the total phenol and flavonoid contents, antioxidant activity and concentration of some phenolic compounds. Antioxidant activity was ...

nanocomposites based on phenolic resol and novolac resins and cloisite 30b were prepared. different kinds of phenolic resins and clay content were studied with respect to the morphology and mechanical properties of the polymer silicate layers. the phenolic resins, namely resol, novolac and their mixture and four different percentages of clay contents, 0.5, 1, 2 and 5 wt% have been considered. x...

In the present work, the fresh juice of black mulberry (Morus nigra) was tested for antimicrobial activity against various pathogenic microorganisms. Total antioxidant contents, total phenolic contents, total anthocyanins, trace minerals, total acid contents, total solids and ascorbic acid content were also evaluated. The results showed good antimicrobial activity both for Grampositive and Gram...

A total of 9 plant extracts were tested, using two different kinds of extracting methods to evaluate the antioxidant and antimicrobial activities from Pilea microphylla (Urticaceae family) and including toxicity test. Antioxidant activity were tested by using DPPH free radical scavenging, also total phenolic contents and total flavonoid contents were determined. Toxicity assay carried out by us...

We investigated the role of phenolic and phenolic-related traits of the leaves of mountain birch (Betula pubescens ssp. czerepanovii) as determinants of their suitability for the growth of larvae of the geometrid Epirrita autumnata. As parameters of leaf suitability, we determined the contents of total phenolics, gallotannins, soluble and cell-wall-bound proanthocyanidins (PAS and PAB, respecti...
