این تحقیق با هدف شناسایی مواد موثره کپسول گیاه lindl. papaver bracteatum تیره خشخاش (papaveraceae) و تعیین اثر شیب، ارتفاع و خاک بر کمیت و کیفیت آن مواد در کوهستان رینه مازندران انجام گرفت. بدین منظور گرزهای 50 پایه از این گیاه در دو مرحله قبل از تکامل و بعد از تکامل گرز از دو شیب 10-4 درصد و بیشتر از 40 درصد ارتفاعات 2500-2400 و 3000-2900 متر از سطح دریا به همراه نمونه خاک جمع آوری و برداشت گ...
Codeinone (3) was efficiently and directly converted to 14-hydroxycodeinone (1) by catalytic air oxidation in aqueous solution. A number of simple manganese and copper salts were identified to be effective catalysts, including MnSO4, KMnO4, and CuSO4. An appropriate reducing agent, such as sodium thiosulfate, is required in the reaction mixture presumably for the reduction of a detrimental pero...
Noroxymorphone is a pivotal intermediate in the synthesis of important opioid antagonists such as naloxone and naltrexone. The preparation noroxymorphone from thebaine, naturally occurring opioate isolated poppy extract, multistep sequence which oxycodone first generated then N- O-demethylated. Both demethylations are problematic safety sustainability viewpoint, they involve harmful reagents al...
