From the MeOH extract of Bombycis corpus inoculated by Beauberia bassiana 101A, two cyclodepsipeptides, bassianolide (1) and beaubericin (2), were isolated and their structures were determined by one and two dimensional NMR studies. Compounds 1 and 2 exhibited cytotoxicity against cultured human tumor cell lines.

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 $11.37{\;}\mu\textrm{g}/m$.
