Four new limonoids from the seeds of Chukrasia tabularis A. Juss.

Publication date: March 2017 Source:Phytochemistry Letters, Volume 19 Author(s): Li Yi, Hongjian Zhang, Xiaomeng Tian, Jie Luo, Jun Luo, Lingyi Kong Two new C-15 enolic acyl phragmalin-type limonoid orthoesters (1-2) which possessed a C-15-propionyl phragmalin skeleton and two new mexicanolide-type limonoids (3-4) were isolated from the ethanol extract of seeds of Chukrasia tabularis A. Juss. Their structures were established on the basis of spectroscopic analyses and electronic circular dichroism (ECD) exciton chirality method. Additionally, all of the compounds were screened against three human tumor cell lines MCF-7, SMMC-7721, and U2OS. Graphical abstract
