Ilicis routundae cortex derivants and application thereof in preparing medicament capable of resisting tumors

The invention discloses Ilicis routundae cortex derivants and an application thereof in preparing a medicament capable of resisting tumors. Ilicis routundae cortex acid is obtained by extracting, separating and purifying traditional Chinese medicine Ilicis routundae cortex to serve as a lead compound; the lead compound is subjected to corresponding chemical reaction to prepare a series of derivants. The pharmacological test proves that the Ilicis routundae cortex derivants have the function of resisting tumor activity and have inhibition action on prostatic cancer cells, lung cancer cells, liver cancer cells, cervical cancer cells and gastric cancer cells; and the inhibiting effects on the tumor cells by the derivants are superior to that of parent nucleus Ilicis routundae cortex.
