The acivity-guided fractionation on the MeOH extract of Bombycis corpus inoculated by Beauberia bassiana 101A led to the isolation of two steroids, 24-ethycholest-4-ene-3,6-dione (1) ergosterol peroxide (2), as active principles. Compounds 1 and 2 exhibited cytotoxicity against cultured human tumor cell lines, A-549, SK-OV-3, SK-MEL-2, XF-498 and HCT-15 with ED50 values ranging from 3.42 to $11.37{\;}\mu\textrm{g}/m$.
