Green Kiwifruit allergy has been widely described and the responsible allergens have been identified. However, no published data or studies have been reported with Gold Kiwifruit. The first case of sensitisation after the ingestion of green kiwifruit was described in 1981. Since that time, a variety of allergic reactions have been related to the ingestion of this fruit. The most common manifest...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Use of metal nanoparticles in biological system has recently been recognised although little is known about their possible effects on plant growth and development. Nanoparticles accumulation, translocation, growth response and stress modulation in plant system is not well understood. Plants exposed to gold and gold nanoparticles have been demonstrated to exhibit both positive and negative effec...

   The use of plant extracts for nanoparticles synthesis are green, economical and cost effective approach.  The present study reports the bio-synthesis of gold nanoparticles (Au NPs) using leaf extract of Terminalia arjuna. After exposing the gold ions to aqueous solution of leaf extract, rapid reduction of gold ions into gold nanoparticles is observed within few minutes. The characterizat...

The development of reliable processes for the synthesis of gold nanoparticles is an important aspect of current nanotechnology research. Recently, reports are published on the extracellular as well as intracellular biosynthesis of gold nanoparticles using microorganisms. However, these methods of synthesis are rather slow. In present study, rapid and extracellular synthesis of gold nanoparticle...

Use of simple synthetic drug called Chin - Yeh, Gold - plus - plant juice or red colloidal gold. Gold made body everlasting and the herbal principle, as soul, increased life-span. Dialectally it was called Kim - Iya. Arabicized as Al - Kimiya it finally appeared as Alchemy. Chin - Yeh as drug was only brick - red when mercury, and sulphur - with traces of gold were sublimated there resulted Chi...

The seeds of various plants were used as weights because their mass reputedly varies so little. Carob (Ceratonia siliqua), which has given its name to the carat, is particularly famous in this regard. But are carob seeds unusually constant in weight and, if not, how did the myth arise? The variability of seeds sampled from a collection of carob trees (CV=23%) was close to the average of 63 spec...

Here we reported the extremely simple one-pot synthesis of silver and gold nanoparticles in a rapid manner. Aqueous leaf extract of the most admired energy plant Jatropha curcas is used as reducing agent here. An alternate and safe energy source, house-hold microwave oven constituted the reaction chamber. Silver and gold nanoparticles were characterized by UV-visible, FT-IR, Powder XRD techniqu...

Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. In the carbon-in-pulp process adsorption occurs after the leaching cascade section of the plant, and in the carbon-in-leach process leaching and adsorption occur simultaneously...
