Polyphenol oxidase (PPO) was purified from fresh ginseng roots using acetone precipitation, carboxymethyl (CM)-Sepharose chromatography, and phenyl-Sepharose chromatography. Two isoenzymes (PPO 1 and PPO 2) were separated using an ion-exchange column with CM-Sepharose. PPO 1 was purified up to 13.2-fold with a 22.6% yield. PPO 2 bound to CM-Sepharose, eluted with NaCl, and was purified up to 22...

Background & Aim: German chamomile is one of the most important medicinal plants. So, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. Determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of German chamomile (Matricaria chamomilla L.) populations...

Lycopene bioavailability from a single dose of fresh tomatoes or tomato paste (23 mg lycopene) ingested together with 15 g corn oil was compared by analyzing carotenoid concentrations in the chylomicron fraction. The lycopene isomer pattern was the same in both fresh tomatoes and tomato paste. The triacylglycerol response in chylomicrons was not significantly different after both treatments. In...

In order to study the effect of silver nanoparticles and magnetic field on Raphanus sativus. experiments were carried out with four treatments in 10 days. Treatments were including (CON) control, (MF) magnetic field with B=1.8 mT for 1h per day in 10 days, (SNPs) silver nanoparticles (50 ppm), (MF+SNPs) magnetic field plus silver nanoparticles. Results showed that silver nanoparticles (SNPs) ha...

a field experiment was conducted at wondo genet agriculture research center under irrigated condition to determine the effect of intra and inter-row spacing on growth and yield of artemisia (artemisia annua l.) during the two successive seasons of 2013 and 2014. factorial combinations of four intra-rows (40, 60, 80, 100 cm) and four inter-row plant spacing’s (60, 80, 100, 120 cm) were laid out ...

This investigation was carried out at the experimental farm of Medicinal and Aromatic plants Research Department, Horticulture Research, Dokki, Giza during two successive seasons of 2009/2010 and 2010/2011.The research aimed to study the effect of compost rates (2,4and 8 ton/fed) and some biofertilizers (Azotobacter Chroococcum, Bacillus megaterium, Bacillus circulanse) alone or all strains in ...
