摘要
Four new B-seco-limonoids, toonamicronoids A-D (1-4), together with four known ones, toonaciliatin H-J (5-7), and toonacilianin A (8), were isolated from Toona microcarpa. Their structures were identified on the basis of ESIMS, HREIMS and 1D/2D NMR analysis. Compounds 1 and 4 showed moderate cytotoxicities against HL-60 with the IC(50)values of 17.3 +/- 1.5 and 22.7 +/- 1.9 mu M, respectively.
