Application of ergosterol and ergosterol liposome prepared from ergosterol

The invention discloses application of ergosterol and ergosterol liposome prepared from the ergosterol, and particularly relates to the application of the ergosterol on treating lung cancer, and the ergosterol liposome for treating the lung cancer. In the ergosterol liposome, the drug loading capacity of the ergosterol is 5-20 wt%; the liposome consists of lecithin and cholesterol, wherein the mole ratio of the lecithin to the cholesterol is (1:1)-(7:1). The ergosterol liposome disclosed by the invention has remarkable lung cancer resistant effects, low cytotoxicity, small damage to human bodies, and target ability.
