Abstract

Two new compounds beauvericins M1 (1) and S1 (2) were isolated from Bombyx batryticatus. Their structures were established as (3α,6α)-3-benzyl-6-secbutyl-4-methylmorpholine-2,5-dione (1) and (5α,8α)-epidioxyergosterol-24-one-6,22-dien-3β-ol (2) by various spectroscopic techniques including 1D NMR ((1)H NMR and (13)C NMR), 2D NMR (HSQC, HMBC, (1)H-(1)H COSY, NOESY), and HR-ESI-TOF-MS.

Keywords: Bombyx batryticatus; beauvericin M1; beauvericin S1; ergosterol; morpholinedione.
