目的 探究不同产地蒙古黄芪Astragalusmembranaceus主要药效成分的含量差异,以及不同药效成分含量与经纬度、光照、温度、水分等地理气候因子的相关性。方法 基于HPLC法测定了甘肃定西、山西大同、陕西榆林等7个产地蒙古黄芪的黄芪甲苷... 目的 探究不同产地蒙古黄芪Astragalusmembranaceus主要药效成分的含量差异,以及不同药效成分含量与经纬度、光照、温度、水分等地理气候因子的相关性。方法 基于HPLC法测定了甘肃定西、山西大同、陕西榆林等7个产地蒙古黄芪的黄芪甲苷、黄芪皂苷I等4种皂苷类成分和毛蕊异黄酮、芒炳花素等8种黄酮类成分的含量,通过方差分析比较各产地蒙古黄芪成分含量的差异,并采用相关性分析及通径分析探究地理气候因子与成分含量的相关性。结果 不同产地蒙古黄芪的12种药效成分含量均存在显著差异,其中山西大同产黄芪的黄芪皂苷、黄酮苷类成分含量较高,甘肃定西产黄芪的黄酮苷元类成分含量较高。相关性分析结果表明,在经度较高的地区有利于黄芪皂苷及黄酮苷类成分的积累,在经度较低地区有利于黄酮苷元类成分的积累。进一步通径分析结果表明,经度对药效成分的影响主要与降水量和光照条件有关。此外,9月较高的太阳辐射和4月较少的降水量有利于黄酮苷类成分的积累。结论 皂苷及黄酮类成分含量在不同产地的蒙古黄芪间差异显著,经度、9月太阳辐射和4月降水量对上述成分的积累影响较大。 展开更多

Since 2000, based on a wealth of geological heritage sites and experience with their conservation, China has formally approved the establishment of forty four National Geoparks, whose distribution and characteristics are dominated by structural setting and neotectonism. Conserving and developing the sites have brought about favorable social, economic and environmental benefits, and created a positive climate for their inclusion in the worm Geopark network under the patronage of UNESCO. 展开更多

Objective: diabetes belongs to one of the higher clinical incidence of endocrine diseases, the identity of diabetes patients for long-term hyperglycemia. At the same time, diabetes patients in the early disease have no obvious clinical symptoms. Therefore, early diabetes patients usually do not realize the existence of the disease, and until the condition is serious, affect the normal life to medical patients was found. Clinical usually use oral hypoglycemic treatment of patients, but patients in the process of taking hypoglycemic drugs easily a variety of adverse reactions, and different drugs to the patient body adverse reactions. This article will be based on the type of oral hypoglycemic drugs to its adverse reactions, analyze its research progress, to provide reference for clinical treatment of diabetes patients. 展开更多
