研究甘肃不同产区黄芪在不同的土壤、气候等环境条件对黄芪药材中有效成分含量的影响.采购甘肃会川、首阳、岷县、陇西、通渭等不同产区的黄芪药材,根据《中华人民共和国药典》标准分别测定不同产区黄芪的水分、灰分、浸出物的含量,应用HPLC-UV法分别测定不同产区黄芪有效成分甲苷的含量.色谱条件:Kromasil C18柱(250 mm×4.6 mm),流动相为乙腈∶水(32∶68),流速1.0 mL/min,波长203 nm.结果 显示,甘肃不同产区以及同一产区不同规格的黄芪药材,其干燥根中有效成分甲苷的含量存在较大差异.说明不同的栽培管理技术以及不同环境条件下,中药材中有效成分的含量会受到一定影响,在生产实践中应注重药材有效成分的含量对药材品质的影响.

研究A、B、C3个配方的大蒜素长效驱避剂的缓释性能及其与普通大蒜素水乳液的差异.建立羊毛中大蒜素的气相色谱检测方法,对影响羊毛中大蒜素检出的萃取时间、萃取液体积、萃取温度及羊毛浸泡时间进行单因素试验条件优化与筛选,采用所建立方法对浸泡过相应驱蜱剂的羊毛分别于0d、1d、2d、3d、5d、8d、12 d、18 d检测其大蒜素含量,并以第0天羊毛中所测得的大蒜素含量为初始值,其他各时间点为余留值,得到不同配方的大蒜素的相对释放率,绘制时间/相对释放率曲线,结合不同处理组同一时间点的大蒜素含量进行差异性分析,对
在甘肃不同生态区域收集宽叶羌活种苗,制定宽叶羌活种苗质量分级标准,为宽叶羌活规范化种植提供理论依据.以宽叶羌活单根鲜重、根粗、根长为评价指标,将收集到的33份宽叶羌活种苗采用K均值聚类法分为3类,根据聚类分析结果和生产实际制定宽叶羌活种苗质量分级标准.结果 显示,甘肃省宽叶羌活种苗划分成3个等级:一级种苗单根鲜质量2.1g≤W＜3.0 g,根长19.0 cm≤L＜26.0 cm;二级种苗单根鲜质量W≥3.0 g,根长L≥26.0 cm;三级种苗单根鲜质量1.2 g≤W＜2.1 g,根长12.0 cm≤L＜
Grain size is one of the most important agronomic traits controlling grain yield. Development of novel germplasm with large grains would be beneficial for crop improvement. We report the genetic identifi-cation and functional analysis of the LONG GRAIN 6
建立UPLC法测定二十五味竺黄散中马兜铃酸Ⅰ的方法.采用UPLC法对二十五味竺黄散中的马兜铃酸Ⅰ的含量进行测定.色谱柱为Thermo Hypersil GOLD(100 mm×2.1 mm,1.9 μm),流动相为乙腈-0.5％冰醋酸(30∶70);柱温35℃,进样量为2μL;流速是0.3 mL/min,检测波长为250 nm.结果 表明,该方法重复性、精密度和稳定性试验的RSD均小于2％,马兜铃酸Ⅰ对照品在0.9998～49.9900 ng范围内线性关系良好(R2=0.999),平均加样回收率为94.1
Appearance and cooked rice elongation are key quality traits of rice. Although some QTL for these traits have been identified, understanding of the genetic relationship between them remains limited. In the present study, large phenotypic variation was obs
Increased grain yield (GY) and grain protein concentration (GPC) are the two main targets of efforts to improve wheat (Triticum aestivum L.) production in the North China Plain (NCP). We conducted a three-year field experiment in the 2014-2017 winter whea

Intercropping of maize (Zea mays L.) and peanut (Arachis hypogaea L.) often results in greater yields than the respective sole crops. However, there is limited knowledge of aboveground and belowground inter- specific interactions between maize and peanut
