The invention relates to a method for the preparation of amorphous silibinin (or its synonyms: silybin or silibin) derived from a milk thistle fruit extract having an increased release rate and improved absorbability or bioavailability, and to the use of amorphous silibinin for the treatment or prevention of liver diseases, preferably for the treatment of viral hepatitis, e.g. hepatitis B or C, in particular in a patient who will undergo or has undergone liver transplantation. Preferably, the amorphous silibinin is adapted for oral administration.本發明關係到一用於製備非晶型水飛薊賓(silibinin)(或其同義辭silybin或silibin)之方法,該化合物係源自於水飛薊果實之萃取液,具有增加之釋出率及經過改善之可吸收性或生物可利用率,且關係到使用非晶型水飛薊賓於治療或預防肝臟疾病,較佳用於治療病毒性肝炎,例如B型或C型肝炎,尤其是用於即將或已經接受肝臟移植之病患。較佳者為,使非晶型水飛薊賓適合於口服給藥。
