Abstract 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.
