Phytochemical investigation of Eupatorium hualienense (C. H. Ou, S. W. Chung, C. I. Peng) has resulted in the isolation of the new sesquiterpene lactones 1-5, named eupahualins A-E, along with the known heliangolide eupasimplicin B (6). The structures of the isolated compounds were established through detailed spectral analyses, especially by means of 2D-NMR techniques. Compounds 1-4 and 6 showed significant activities against cell lines of human chronic myelogenous leukemia (K562) and human bone cancer (U2OS).
