Determination of ephedrine bioavailability.

Determination of ephedrine and pseudoephedrine by field-amplified sample injection capillary electrophoresis.

A simple and rapid capillary electrophoresis method was developed for the separation and determination of ephedrine (E) and pseudoephedrine (PE) in a buffer solution containing 80 mM of NaH2PO4 (pH 3.0), 15 mM of β-cyclodextrin and 0.3% of hydroxypropyl methylcellulose. The field-amplified sample injection (FASI) technique was applied to the online concentration of the alkaloids. With FASI in t...

Selective determination of diphenhydramine in compound pharmaceutical containing ephedrine by flow-injection electrochemiluminescence.

On the basis of the structural interactions between diphenhydramine (DPH) and ephedrine (EPH) to enhance electrochemiluminescence (ECL) intensity, a flow-injection ECL analysis of DPH in the present of EPH by utilizing tris(2,2'-bipyridine)ruthenium(II), (Ru(bpy)(3)2+) has been reported. In the optimized experimental conditions, the linear ECL response to concentrations of DPH is from 2.00 to 4...

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Atropine and ephedrine adsorption

The purpose of this study was to compare daily changes in the concentration of atropine or ephedrine sulfate solutions that had been stored up to 4 days in plastic or glass syringes. Sets of three plastic and one glass syringe were used for each drug; the glass syringes acted as controls. Each set of syringes was labeled as day 0, 1, 2, 3, or 4. Syringes with medication were laid horizontally, ...
