The relationship between phenolics and flavonoids synthesis/accumulation and photosynthesis rate was investigated for two Malaysian ginger (Zingiber officinale) varieties grown under four levels of glasshouse light intensity, namely 310, 460, 630 and 790 μmol m(-2)s(-1). High performance liquid chromatography (HPLC) was employed to identify and quantify the polyphenolic components. The results ...

introduction: pulsed dye laser (pdl) has been used to treat acne lesions and scar erythema by interrupting superficial vasculature. salicylic acid chemical peels are employed chiefly due to their lipophilic, comedolytic, and anti-inflammatory properties. although studies have looked at peels and laser therapy independently in acne management, we examined these treatments in combination. our pri...

a field study was carried out at the islamic azad university of arak in 2010 to find out the effects of salicylic acid and water deficit stress on oil yield and some physiological characteristics of different varieties of sunflower. the experiment was laid out in a factorial split plot based on a randomized complete block design with four replications. treatments consisted of water stress in th...

This paper describes the antioxidant and antimicrobial activities and phenolic components of different solvent (absolute methanol, absolute ethanol, absolute acetone, 80% methanol, 80% ethanol, 80% acetone and deionized water) extracts of leaves, flowers and bark of Gold Mohar [Delonix regia (Bojer ex Hook.) Raf.]. The extract yields from leaves, flowers and bark ranged from 10.19 to 36.24, 12....

Analysis of DRIFTS spectra was used for a quantitative study of competitive adsorption of myristic and salicylic acids onto kaolinite or gamma-alumina. Peaks unique to the ring or the chain were selected and single molecule studies used as calibration. Samples were exposed to hexane solution containing equal molecular quantities of each acid. The surface loading of salicylic acid was not influe...

Soil cultures, enrichment cultures, and pure culture isolates produced substantial quantities of salicylic acid from naphthalene in a mineral salts medium containing NH(4)Cl as the nitrogen source. However, when KNO(3) was substituted for NH(4)Cl, these same cultures failed to accumulate detectable quantities of salicylic acid but did turn the medium yellow. When an isolate identified as a Pseu...

in order to investigate the effects of salicylic acid on some growth and stomatal characteristics of calendula plant, a factorial experiment was conducted based on completely randomized design with five replications in the research greenhouse of shahid bahonar university of kerman in 2013. salt stress levels including 1, 3, 5, 7 and 9 mmhos/cm were applied to the soil and salicylic acid solutio...

soil and water sources salinity are important constrains which threat the sustainable agriculture production in iran. in order to evaluate the effect of different antioxidants and salinity levels on germination and seedling properties of two medicinal species (cnicus benedictus l.), and (cichorium intybus l.), an experiment was conducted using a factorial based on completely randomized design w...
