Abstract:
An icariside compound as shown in Formula I wherein the compound is a natural chemical component in the traditional Chinese herbal epimedium or a chemically modified or a totally synthetic product based on the natural component. The compound can be used for preparing pharmaceuticals, health care products, cosmetic and skin care products and the like for improvement of immunity in a human body.

Claim (Index 4):
A method for preparation of any icariside compound of Formula I, wherein Icariside compounds\n (Icariside derivatives) \n wherein the groups represented by R 1 , R 2 , and R 3  in formula I are defined as follows: (1) R 1  is selected from H, OH, OCH 3 , CH 3 COO, CH 3 , CF 3 , NH 2 , CH 3 NH, CH 3 CONH, CN, Br, Cl, F; (2) R 2  is selected from H, OH, OCH 3 , CH 3 COO, NH 2 , CH 3 NH, (CH 3 ) 2 N, CH 3 CONH, CN; (3) R 3  is selected from H, OH, OCH 3 , OC 2 H 5 , OC 3 H 7 , CH 3 COO, CH 3 , CF 3 , C 1 -C 6 \u2014NH 2  (wherein C 1 -C 6  is an alkyl group, a cycloalkyl group, an olefin group, cyclic olefin group, in particular a cyclopentylamino group, a cyclohexylamino; and a morpholinyl group, a methylpiperazinyl having 1 to 6 carbon atoms), NH 2 , CH 3 NH, (CH 3 NH, (CH 3 ) 2 N, (CH 3 CH 2 ) 2 N, CH 3 CONH, CN, Br, Cl, F, amino acid acyl, amino acid acylamino (R\u2032\u2014CH\u2014CONH\u2014), oligopeptideacyl, oligopeptide amido group, and so on, said method comprising the step of obtaining icariside compounds of formula I by derivatization of a natural product including but not limited to icariside I or icariside C.
