Structure elucidation and complete NMR spectral assignments of new furostanol glycosides from Solanum torvum.
Two new furostanol glycosides, torvosides O (1) and P (2), were isolated from leaves of Solanum torvum. Their structures were completely and unambiguously assigned by one- and two-dimensional NMR techniques ((1)H NMR, (13)C NMR, TOCSY, HSQC, ROESY and HMBC), ESI-MS spectrometry and chemical methods.
