摘要
Two new limonoids, 12-ethoxynimbolinins G and H(compounds 1 and 2), and one known compound, toosendanin(Chuanliansu)(compound 3), were isolated from the bark of Melia toosendan. Their structures were elucidated by spectroscopic analysis and X-ray techniques. The absolute configuration of toosendanin(3) was established by single-crystal X-ray diffraction. Compounds 1-3 were evaluated for their cytotoxicity against five tumor cell lines.
