胡椒碱

In the present study, we demonstrated that the antidepressant-like effects of piperine and its mechanisms might be involved by up-regulation of the progenitor cell proliferation of hippocampus and cytoprotective activity.

胡椒碱具有较好的抗抑郁作用，其作用可能是通过调控神经干细胞的增殖、迁移和分化及对功能性神经再生的保护和促进作用实现的。

The fluorescence characteristics of the complex of piperine with cation in micellar system were studied.At the same time,the influence of experimental condition on the fluorescence intensity was also studied.

研究了金属离子存在下胡椒碱在胶束体系中的荧光特性及实验条件对荧光强度的影响。

Ultimately,we used quadratic polynomial stepwise regression analysis,according to the correlation coefficient variable size,to look for curcumin with the best ratio of piperine.

利用均匀设计的方法进行分组，检测小鼠眼球血清三酰甘油和胆固醇的含量，寻找姜黄素与胡椒碱的最佳配比。

The effect of high-dose irradiation of pepper powder on piperine content was studide.

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.
