A new minor 3-amino steroidal alkaloid has been isolated from the leaves of Solanum capsicastrum and characterised as 7β-hydroxy-O-methylsolanocapsine (3) on the basis of IR, MS, 1H and 13C NMR spectral analyses. The assignments of 13C chemical shifts of the OMe and C-24 carbons of O-methylsolanocapsine (6) had to be revised on the basis of INEPT and selective proton decoupling experiments. © 1988.
