Correlation between Environmental Factors and the Quality of Radix Polygalae / 中国药房

OBJECTIVE:To analyze the effects of environmental factors (soil,climate,etc.) on the quality of Radix Polygalae.METHODS:The contents of polygalic acid were determined by HPLC.Climate factors including altitude,average annual temperature,average temperature of July,annual precipitation,annual sunshine hours and non-frost days were collected through on-site inspection or from the local meteorological data. Water content,pH and nutritional elements of the soils were determined by routine method,and the reletionship between the content of polygalic acid and the factors were analyzed.RESULTS:There was linear relationship between the content of polygalic acid and climate factors such as average temperature of July,annual precipitation,annual sunshine hours and non-frost days.There was also linear relationship between polygalic acid and soil factors such as total nitrogen,total phosphor,available phosphor,available kalium,organic matters and water content. CONCLUSION:The main climate factors that affect polygalic acid content were annual sunshine hours and non-frost days,while the main soil factors affecting the content of polygalic acid were the content of available phosphor and soil water content.

Study on enhancing bioavailability of paeoniflorin by combined use with Chinese herbs for inner-warming / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the influence of Chinese herbs for inner-warming on the bioavailability of paeoniflorin (PF) and its mechanism.</p><p><b>METHODS</b>Chinese herbs (pepper fruit, evodia fruit, cassia bark, fennel fruit and prickly-ash peel) were separately used in combination with PF for gastrogavage to mice. Reversed phase high-performance liquid chromatography was used to determine the plasma concentration of PF in mice after medication. The bioavailability of PF was calculated and compared, taking single use of red peony root for control.</p><p><b>RESULTS</b>The pharmacokinetics of PF in mice was conformed to the one-compartment model, as combined use with Chinese herbs for inner-warming, the relative bioavailability of PF was 137.22% for pepper fruit, 123.62% for evodia fruit, 108.39% for cassia bark, 226.02% for fennel fruit and 116.73% for prickly-ash peel, there were difference of Cmax and AUC(0-infinity) in comparison of these data with the control group (P < 0.05), but with no difference of tmax (P > 0.05).</p><p><b>CONCLUSION</b>The Chinese herbs used in this experiment in combination with red peony root could enhance the bioavailability of PF, which illustrated the scientific meaning of the recipe combination of Chinese herbs for activating blood circulation and inner-warming viewing from pharmacodynamics.</p>
