Application of Coordination of Silver Ion in Separation and Determination of Natural Active Substances

A review on the application of coordination of Ag(Ⅰ)ion in separation and determination of natural and active substances(including DHA,EPA,α-linolenic acid,arachidonic acid,β-elemene,5Fin pteris flag system,tocopherol and tocotrienol etc.)was presented,relating mainly to the mechanism of coordination of Ag(Ⅰ) with the-C=C- bond;the separation and purification of the aboved mentioned 8natural and active substances; and the combination of separation by coordination of Ag(Ⅰ)with the methods of HPLC and TLC for the determination of the 8substances(31ref.cited).
