Research strategies for feed additives and veterinary medicines from side products of Chinese medicine resources industrialization / 中国中药杂志

The global antimicrobial resistance has been a big challenge to the human health for years. It has to make balance between the safety of animal products and the use of antimicrobials in animal husbandry. Any methods that can minimize or even phase out the use of antimicrobials in animal husbandry should be encouraged. We herein describe the research strategies for feed additives and veterinary medicines from the side products of Chinese medicine resources industrialization. Killing two birds with one stone-besides the major purposes, the rational utilization of non-medicinal parts and wastes of industrialization of Chinese herbal medicines is also achieved under the proposed strategies.

A new 6,6a-offbenzophenanthridine alkaloid from Macleaya cordata / 中国中药杂志

A new alkaloid was isolated from the leaves of Macleaya cordata with 95% ethanol extracted and its isolation was by column chromatography and preparation HPLC. The new structure was elucidated as 6'-hydroxy-2',3'-dimethoxyarnottianamide on the basis of its spectroscopic date.

Determination of benzopyrene in red clover extract by high performance liquid chromatography with spectrofluorescence detector / 中国中药杂志

<p><b>OBJECTIVE</b>To establish a high performance liquid chromatography method with spectrofluorescence detector for the quantitative analysis of benzopyrene in red clover extract.</p><p><b>METHOD</b>Analysis was performed on Hypersil C18 column (4. 6 mm x 200 mm, 5 microm) with acetonitrile and water (70: 30) as mobile phase; The excitation wavelength and emission wavelengh were 368 nm and 405 nm, respectively; Flow rate was 1.0 mL x min(-1).</p><p><b>RESULT</b>The linear range was 0.93-37.2 ng x mL(-1), and r = 0.9992 (n = 5). The average recovery of benzopyrene was 85.2% (n = 9).</p><p><b>CONCLUSION</b>The method was convenient and accurate with good recovery.</p>

Design of a wireless ambulatory blood pressure monitoring system based on ARM / 中国医疗器械杂志

A design of the wireless ambulatory blood pressure monitoring system has been presented based on ARM embedded microprocessor and GPRS module for the extention of native mobile telemedicine. The whole system framework and flow chart have been introduced in detail. Based on RBF neural networks, the ambulatory blood pressure data curve has been simulated, and the trend curve provides a reliable gist for the prevention, treatment, diagnosis and therapeutic efficacy of cerebrocardiac diseases.

Simultaneous determination of resveratrol, emodin, chrysophanol, physcion, in root of Polygonam cuspidatum and its extract by HPLC / 中国中药杂志

<p><b>OBJECTIVE</b>To establish a HPLC method for simultaneous determination of resveratrol, emodin, chrysophanol, physcion in root of Polygonum cuspidatum and its extract.</p><p><b>METHOD</b>The separation was performed in a Hypersil ODS C18 column with a mobile phase of Acetonitrile-1%HAc. The flow rate was 1.0 mL x min(-1) and detection wavelength was at 287 nm.</p><p><b>RESULT</b>The mean recovery and RSD of resveratrol, emodin, chrysophanol, physcion was 101.8%, RSD 1.7%; 96.2%, RSD 1.4%; 99.7%, RSD 1.0%; 98.60%, RSD 0.97% respectively.</p><p><b>CONCLUSION</b>The method is accurate, simple and reliable. It can be used for quality control of P. cuspidatum and its extract.</p>
