Abstract:
Two new gamma-pyranone derivatives and a new triterpene, together with eight known compounds, were isolated from the aerial parts of Erigeron annuus. Their structures were elucidated by spectroscopic methods. Besides, the anti-tumor activities of the gamma-pyranone derivatives to human hepatoma (SMMC-7721), human embryo liver (L-02) and human leukemia (HL-60) cells were evaluated.
