但是由于凹凸棒石孔道直径小于大多数分子及水合离子的直径，除少数简单分子和离子外，多数分子和离子都不能进入凹凸棒石孔道，而且凹凸棒石选择性吸附水分子，因而在多数情况下，凹凸棒石对吸附质的吸附不是内表面吸附，而是外表面吸附。并且外表面吸附是胶体和离子交换吸附。本文阐述了凹凸棒石的孔道直径、吸附选择性、体系pH 值及凹凸棒石和蒙脱石胶体颗粒的互相作用对凹凸棒石吸附性能应用的制约。

The main conclusions are as follows:The vitellin of Chrysopa septempunctata was extracted with 0.4mol/L NaCl and then precipitated in cold distilled water. Ion exchange chromatography and proteic gel recovery were used to purify it further. SDS-PAGE analysis shows that the vitellin is composed of two subunits, the large one 165kDa and the small one 46kDa.Then automatic amino acid analyzer was used to analyse amino acid composition of vitellin.

In the course of establishing standard operating procedure, The temperature, time , the feasibility without decorticating and efficiency were investigated when alliinase was deactivated used a dry heating apparatus in tunnel type, but the efficiency can be achieved less than 70%, need to be improved; The reformative cribriform plate has been proved to be good in practice result in pulping enzyme-deactivated garlic without dehulling; The extraction efficiency achieved more than 90% when volumic ratio of 20% alcohol and water is 3 I 1 and 2:1 was adopted to extract alliin two times respectively; During exact filtration, the ratio of diatomite in precoating and filtration was 3% and 1% respectively, the losses of alliin adsorbed by diatomite in extraction solution were not remarkable. In the stage of alliin isolation by ion exchange resin, three simple and sensitive detected measures were successfully adopted to control the whole process; the efficiency of alliin isolation was similar to laboratory results; The alliin yield was over 50% in acidic fractions and the purity quotient of alliin achieved above 50% after drying; Furthermore, the phenomenon was found that losses of alliin were seriously affected by the temperature and time periods in concentration.
