Trichilin-type limonoids isolated from the fruits of Trichilia connaroides / 药学学报

ABSTRACT

Two new trichilin-type limonoids were isolated from the fruits of Trichilia connaroides along with two known limonoids, 3α-deacetylamoorastatin (3) and mesendanins K (4). Their planar structure and relative configuration were elucidated by comprehensive analyses of HR-ESI-MS, 1H NMR, 13C NMR, HSQC, HMBC and ROESY data. An antitumor activity assay showed that compounds 1, 2 and known compound 4 had weak cytotoxicity against a human cervical cancer cell line (HeLa).
