陈家华，高剂量辐照胡椒粉对胡椒碱影响研究

The process of binding was a spontaneous molecular interaction with increasing of entropy and decreasing of Gibbs free energy. Thus the interaction of piperine with BSA was driven mainly by hydrophobic force.

通过热力学参数的计算，确定胡椒碱与牛血清白蛋白的相互作用是一个熵增加和吉布斯自由能降低的自发过程，主要作用力为疏水作用力。

Starting from piperonal, the initial total synthesis of CET involved BischlerNapieralski reaction, 3, 2-sigmatropic rearrangement, unusual Nazarov-type electrocyclization, and autoxidative dehydrogenation of desmethylcephalotaxine to desmethylcephalotaxinone etc.

第一条路线我们以胡椒醛为起始原料，经Bischler-Napieralski反应，[3，2]-σ重排，6-6环系到7-5环系的还原重排，Nazarov氧化环化；碱性条件下脱甲基三尖杉碱到脱甲基三尖杉酮碱的氧化脱氢等20步反应，完成了三尖杉碱的全合成。

Finally, two components mixture of caprylic acid and lauryl alcohol was used to attestate the validity of the process model. The model was also used in the simulation of the paroxetine free base and PB, compared with experimental outcome, analyzed the relatively error between experiments and simulations to further check the rationality of the model, which is beneficial to establish a more perfect model in the future.

应用正辛酸-十二烷醇对模型进行验证，并应用此模型模拟计算了帕罗西汀碱和胡椒基丁醚的分离过程，进一步验证了此模型的合理性，分析了产生实验值与模拟值相对误差的原因，为进一步完善刮膜式分子蒸馏过程模型奠定了基础。

Experimental results showed that the intrinsic fluorescence of BSA was quenched by peperine molecules forming piperine-BSA complex.

实验结果表明：胡椒碱与BSA形成基态复合物从而猝灭BSA的内源性荧光，猝灭原因主要为静态猝灭和非辐射能量转移作用。

Experimental results showed that the intrinsic fluorescence of BSA was quenched by peperine molecules forming piperine-BSA complex. The mechanism of fluorescence quenching was mainly due to static quenching and non-radiation energy transfer.
