英文摘要: Two new anthraquinone dimers, schimperiquinones A (1) and B (2), together with the known 2-hydroxymethylanthraquinone (3), cleomiscosin A (4), oleanolic acid (5) and sitosterol 3-O-beta-D-glucoside (6) were isolated from the stem bark of Pentas schimperi. Their structures were elucidated on the basis of spectroscopic analysis and comparison with published data or by comparison with authentic samples. To the best of our knowledge, it is the first report of cleomiscosin A, a coumarinolignan from the genus Pentas. Compound 2 exhibited in vitro cytotoxicity (IC50 = 33.05 mu M) against the human cancer cell the BGC-823. (c) 2014 Phytochemical Society of Europe. Published by Elsevier B. V. All rights reserved.
