The contents of andrographolid and 14 - deoxy - l1 , 12 - didohydroandro - grapho | ide contained in leaves of androgrphis paniculata , were analy / ed by reverse ; phase 1iplc . the result of the analyses indicated that the highest , contents of andrographolide and 14 - deoxy - ll , 12 - diclehydroandrographolide were found in the t samples cultivated in zhanjiang and raoping 二、实验研究(一)种植基地考察通过对广东省内传统的穿心莲栽培地区饶平、湛江和广州三个市县基地的调查，并参照gap标准中的环境标准进行了水分和土壤的检测。

So it has increasing commercial demand . escherichia coli and many other microoganism synthesize aromatic amino acids through the condensation reaction between phosphoenolpyru vate ( pep ) and erythrose - 4 - phosphate ( e4p ) to form 3 - deoxy - d - arabinohep tulosonate 7 - phosphate ( dahp ) . pep and e4p are limiting substrates for formation of dahp 大肠杆菌和许多微生物一样，其合成芳香族氨基酸的起始物是由磷酸烯醇式丙酮酸( pep )和4 -磷酸赤癣糖( e4p )二者缩合形成的3 -脱氧- -阿拉伯庚酮糖酸- 7 -磷酸( dahp ) 。

In escherichia coli , arog gene encodes phenylalanine - sensitive 3 - deoxy - d - arabino - heptulosonate - 7 - phosphate synthase isoenzyme arog that catalyzes the first committed step of shikimate pathway . here we study the essential amino acid residues involved in the formation of feedback inhibition site of arog , and the effects of n - terminus on feedback inhibition and its quaternary structure , and the importance of the structural " d2 " symmetry to allosteric inhibition 本博士论文工作以大肠杆菌k - 12来源的arog为研究对象，通过定点突变、反馈抑制实验和酶学动力学参数的测定，深入地研究了arog的反馈抑制位点的特性，并对arog的n -末端在反馈抑制机理和维持稳定四级结构中的作用，以及蛋白质结构的“ d2 ”对称性对酶功能的重要性等进行了具体的研究。

However , a new method is brought forward when dealing with alternating components of emitting light in reflectance detection , which entirely reflect the concentration of oxy - hemoglobin and deoxy - hemoglobin in blood , to improve the system sensitivity on oxygen saturation alternation . the new method is an innovative reference to reflectance oxygen saturation detection 在对检测到的完全反应血液中氧合血红蛋白和脱氧血红蛋白含量变化的脉动分量的处理上，由于透射检测中的处理方法用于反射时灵敏度降低，论文中提出了一种新的能更灵敏反应血氧变化的参量作为确定血氧饱和度的依据。
