Two novel sapogenols, isoesculeogenin A (1) and esculeogenin B (2) of steroidal alkaloid glycosides, lycoperoside F and esculeoside B, respectively, isolated from the ripe tomato have been characterized as (5alpha,22R,23R,25S)-3beta,23,27-trihydroxyspirosolane and (5alpha,22S,23R,25S)-22,26-epimino-16beta,23-epoxy-3beta,23,27-trihydroxycholestane, respectively.
从成熟番茄中分别分离出甾体生物碱苷lycoperoside F和esculoside B的两种新型皂苷元,即异番茄皂苷元A(1)和番茄皂苷元B(2),它们分别被鉴定为(5α,22R,23R,25S)-3β,23,27-三羟基螺旋甾烷和(5α,22S,23R,25S)-22,26-表亚氨基-16β,23-环氧-3β,23,27-三羟基胆甾烷。
