In this study, the racemization kinetic parameters of R-(?)-synephrine, the active phenethylamine alkaloid of Citrus aurantium L., were determined by means of an off-column HPLC method. The results of thepresent study indicated that synephrine racemization is possible at high temperature at both acidic andbasic pH values; therefore, the extraction procedure of R-(?)-synephrine from the plant material should be carried out under specific conditions to preserve the stereochemical integrity and the biological activityof this secondary metabolite. 不要机器翻译的

Answer 1

在这项研究中,racemization动力学参数-(?)[j].生物-synephrine、活跃的柑橘aurantium变得更加机敏,采用反相高效液相色谱法的off-column。目前研究的结果表明,现行racemization是可能在高温条件下的酸性andbasic酸碱值,因此,提取工艺R -(?)-synephrine从植物材料应在特定条件下进行维护stereochemical完整性和生物activityof这次生代谢产物。

Answer 2

在这项研究中,racemization的R -动力学参数(吗?-synephrine),积极的柑橘aurantium变得更加机敏生物碱,采用反相高效液相色谱法的off-column。目前研究的结果表明,现行racemization是可能在高温条件下的酸性andbasic酸碱值,因此,提取工艺R -(?)从植物原料)-synephrine应在特定条件下的stereochemical保存完整和生物activityof这次生代谢产物。
