Three new alkaloids, 3‐O‐acetylveralkamine (1), veralkamine 3‐(β‐D‐glucopyranoside) (2), and 6,7‐epoxyverdine (3), together with five known alkaloids, veramitaline, veralkamine (4), angeloylzygadenine, veratroylzygadenine, and veramiline 3‐(β‐D‐glucopyranoside), were isolated from the whole plants of Veratrum taliense. Their structures were elucidated on the basis of spectroscopic analysis, and the...
Nine new pregnane alkaloids, pachysamines J–R (1–9), together with seven known ones, were isolated from Pachysandra axillaris. The chemical structures of the new alkaloids were elucidated by spectroscopic methods. All the compounds were evaluated for their inhibitory activities against HL-60, SMMC-7721, A-549, SK-BR-3, and PANC-1 cell lines. Compound 15 possessed moderate activities against A-549,...
Two new triterpenoid alkaloids, buxmicrophyllines J and K (1 and 2, resp.), together with four analogues, 3–6, were isolated from the leaves and stems of Buxus microphylla. The structures of the new compounds were elucidated by NMR and MS spectroscopic analyses. The partial assignments of the NMR spectra of 3 were also revised. Compounds 1 and 3–6 were evaluated for their growth inhibitory activity...
