Recently, Kwon et al. reported that the antioxidant activity and total both polyphenol and flavonoid contents of garlic juice were increased by high temperatureand pressure-treatment (130°C, 120 min). We tried to make high temperatureand pressure-treated garlic (HTPG) using an autoclave (130°C, 150 min) rapidly and easily. Our attempt showed that antioxidative activity and total polyphenol cont...

Background & Aim: Marigold or Calendula officinalis L. is a annual herb belongs to the Asteraceae family.  Marigold is a valuable medicinal plant which is used in pharmaceutical industry.  In addition, this plant is cultivated as an ornamental plant. Aim of current study was to evaluate the effect of different concentrations of jasmonic acid (JA), and salicylic acid (SA) on phytochemic...

Polyphenol prevention of iron-mediated DNA damage occurs primarily through iron binding. Once bound, iron in the Fe(2+)-polyphenol complex autooxidizes to Fe(3+) in the presence of O(2). To determine the correlation between the rate of Fe(2+)-polyphenol autooxidation and polyphenol antioxidant ability, kinetic studies at pH = 6.0 in the presence of oxygen were performed using UV-vis spectrophot...

Ginger is one of the commonly used spices that has been exhibited to have pharmaceutical activities. These therapeutic properties are mainly attribute to gingerols and shogaols. To extract these bioactive compounds, subcritical water extraction (SWE) was employed as a green method. The influence of adding co-solvents, temperature, retention time and particle size on extraction yield were invest...

A single tropical plant species can harbour hundreds of endophyte species within its tissues. Otherwise, little is known about the relationship between endophyte colonization, leaf traits, and spectral properties of leaves. We explore those relationships on Coccoloba cereifera, a plant well known for its symbiotic properties. Endophyte richness in C. cereifera was statistically correlated with ...
