Objectives: The study aims is to establish a compound fatty liver model in vitro and in vivo, and then investigate the effects of curcumin (Cur) and tetrahydrocurcumin (THCUR) on the fatty liver.

Investigation of effects of several kinds of ultrasound on the extraction yield of curcumin and total flavanone from curcum;

Extraction and antiseptic effect of curcumin on foods;

Optimum Conditions for Extracting Curcumin with Sodium Dodecyl Sulfate;

Studies on Preparation and Physicochemical Properties of Inclusion Complex of Curcumin with HP-β-Cyclodextrin;

Study on preparation of curcumin lipsomes and the chemicophysical propery;

A new process,taking the residue of yam diosgenin as the raw material preparation activated carbons and moulding coal,the results show that,the activated carbons adsorption performance and the decolorization strength are better than activated carbon of the commercial pellet,prepareing the moulding coal are feasible.

Activated carbon was prepared using the residue in yam diosgenin production as raw material and ZnCl_2 as activator.

The current research progress on synthesis for the lignin-phenolic resin were reviewed with lignin which was from yam diosgenin waste,and including synthesis method of yam lignin-phenolic resin and modified yam lignin-phenolic resin.

This paper mainly studied the way of extraction and purifying the yellow pigment in Dioscorea zingiberensis ,and the effects of light,heat,metal ions and pH value to Dioscorea zingiberensis pigment.
