Two new steroidal saponins, solaprocumosides A (1) and B (2), and a known compound paniculonin B (3) were isolated from the aerial parts of Solanum procumbens. Their chemical structures were determined by analysis of HR-ESI-MS and NMR spectra. Compound 1 had ketone functional groups at C-16 and C-22 of sterol skeleton which is rarely found in nature. Meanwhile, compound 2 could be form by oxidative breakdown C-20/C-22 bonding of a furostane-type saponin. Compounds 1–3 showed weak cytotoxicity against HepG2 cell line with IC50 values of 55.7 ± 1.5, 48.1 ± 2.2, and 78.3 ± 2.4 μM, respectively.

A new δ-truxinic acid sucrose diester and a new ε-truxillic acid sucrose diester (named trigohonbanosides E and F) were isolated from the leaves of Trigonostemon honbaensis. Their chemical structures were determined by extensive analysis of their HR-ESI-MS and NMR spectra. At a concentration of 20 µM, trigohonbanosides E and F exhibited weak inhibitory effects on NO production in LPS-activated RAW264.7 cells with inhibitory percentages of 22.7% ± 1.1% and 18.5% ± 1.4%, respectively.
