Three new steroidal alkaloid glycosides, lycoperosides F-H (1-3), were isolated from tomato fruits (Lycopersicon sculentum) along with lycoperosides A-D, esculeoside A, and rutin. The structures of these glycosides were characterized as the 3-O-beta-lycotetraosides of 23(R)-23-acetoxy-27-hydroxy-27-O-beta-D-glucopyranosyltomatidine (1), (23S,24R)-23-acetoxy-24-O-beta-D-glueopyranosylsoladulcidine-24-ol (2), and 22-isopimpifolidine (3), by means of their spectroscopic data. Also obtained was the new natural product lycoperodine-1 (4).
