From Cacalia deltophylla (collected from Luqu County, Gansu Province), 22 compounds were isolated, of which 15 compounds have been identified. Among them, two compounds are new. They are named as 3-methyl-4-hydro-8-acetyl-furanonaphth-9-one and 1hydroxy-2-methoxy-3-acetyl-4, 8-dimethyl-5, 8-dihydro-naphthalene.

Methods Using petroleum ether to extract crude fat from the Capparis spinosa fruit and identify separately with GC-MS method after methanolysis.

方法］用石油醚提取刺山柑果实中的粗脂肪，甲酯化后，用GC-MS法进行分离鉴定。

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。
