Shuitu Baochi Xuebao, 2005 通过室内培养及玉米盆栽土培模拟试验,采用完全随机区组设计,研究了在山西省大同市山阴县西盐池的苏打碱土上,施用DS-1997、脱硫石膏、风化煤对土壤速效磷含量的影响。研究结果表明:(1)3种改良剂均可降低苏打碱土的pH值;(2)脱硫石膏改良苏打碱土的作用最明显地反映于土壤水溶性盐分的急剧上升,同时伴随着土壤中速效磷含量的急剧下降,因此,脱硫石膏抑制土壤中磷的有效化作用;(3)DS-1997与其他两种改良剂相比,可以更好地增强土壤解磷细菌和碱性磷酸酶活性,增强土壤中磷的释放作用。

Preparation of Monoclonal Antibody against Stevioside and Development of ELISA Method for Stevioside [PDF]
, 2010 甜菊苷(stevioside，ST)为甜叶菊中所含的主要甜味成分，是理想的高甜度、低热量，对糖尿病和高血糖脂有很好疗效的一种新型高安全性甜味剂，也可作为一些药品的品位改良剂和矫味剂，从而广泛应用于食品和药物。目前，甜菊叶中甜菊苷的提取工艺已经日趋成熟，然而甜菊苷的准确含量的检测方法主要是使用HPLC，还存在不足之处，因此，建立简单，快速，准确的甜菊苷定量方法对于甜菊苷的生产和应用都具有极其重要的意义。 本研究利用高碘酸纳法将甜菊苷（ST）分别与人血清白蛋白（HSA）和牛血清白蛋白（BSA）进行偶联 ...
