Disclosed is an anti-tumor plant-medicament sustained-release tablet of elemene which comprises an elemene as an active component and is prepared by formulation of the elemene, a sustained-release agent, a bulking agent, a disintegrating agent, a binder and a lubricant, each component above-mentioned being in the following weight composition: the elemene 10%-15%, the sustained-release agent 3%-15%, the bulking agent 45%-70%, the disintegrating agent 3%-8%, the binder 1%-10%, and the lubricant 1%-8%. The sustained-release tablet of elemene provided in the invention has properties of expansion and adhesion, which in turn enables extending the retention time of the drug on upper and middle sections of the gastrointestinal tract. Therefore, the tablet may be taken b.i.d..times.3, in order to attain reduction in fluctuation of the plasma concentration, maintain effective plasma concentration for a longer period, and reduce the irritation on the gastrointestinal tract. The skeleton-type sustained- and controlled-release formulation has advantages of low cost, easy control, and easy industrialized production.
