Study on moxa sticks burning temperature-time-space curves / 中国针灸

<p><b>OBJECTIVE</b>To study the burning characteristics of moxa stick.</p><p><b>METHODS</b>A self-designed moxa stick burning temperature measuring device, which was assembled with ALTEC intelligence digital setter and SJ-600 thermocouple, was used to conduct next four experiences: 1) embedding a thermocouple inside a moxa stick to measure peak burning temperature; 2) pulling a thermocouple embedded in the moxa stick at the proper rate to detect combustion stability; 3) elucidating temperature distribution of transverse section by measuring the temperature in the center, radius midpoint and lateral; 4) drawing temperature-time-space curves by pulling the thermocouples in the former three observation points.</p><p><b>RESULTS</b>The experiment indicated that the burning temperature peak of three-year moxa stick (Hubei Herbal Medicine St. Qichun Technology Co., Ltd.) was 848 degrees C which had good combustion stability. Furthermore, the temperature in the center, radius midpoint and lateral of transverse section were 843 degrees C, 731 degrees C and 410 degrees C, respectively, and its burning temperature-time-space curves was drawn, which showed the real-time burning temperature and the peak burning temperature and were regarded as ultimate indice to integrate the formers.</p><p><b>CONCLUSION</b>The measuring system elaborately reflecting the burning features of moxa stick may provide reference for manufacture industry of moxa stick quality criteria for its convenience and accuracy.</p>

Observation on scavenging free radical function of Artemisia burning products / 中国针灸

<p><b>OBJECTIVE</b>To study the pharmacologic action of Artemisia burning products.</p><p><b>METHODS</b>The extractions of Artemisia burning products were determined by spectrophotometry. The scavenging ability of Artemisia burning products on DPPH was evaluated. The chemical components and structures of Artemisia burning products were analyzed by Gas Chromatography and Mass Spectrometry (GC-MS).</p><p><b>RESULTS</b>The scavenging ability of extractions from Artemisia burning products was the strongest. Thirty-six chemical components were detected, and the 5-tert-Butylpyrogallol among them had a stronger anti-oxygen capacity, its scavenging free radical ability was 1.55 times and 1.21 times as strong as VitC and BHT, respectively.</p><p><b>CONCLUSION</b>The scavenging free radical ability of 5-tert-Butylpyrogallol extracted from Artemisia burning products is stronger than the natural antioxidant of VitC and artificial synthetic of BHT.</p>
