Antiproliferative oleanane saponins from Meryta denhamii

J Nat Prod. 2008 Jun;71(6):1000-4. doi: 10.1021/np8000464. Epub 2008 Apr 29.

Abstract

Eight new oleanane saponins (1- 8) together with four know saponins (9-12) were isolated from the aerial parts of Meryta denhamii. Their structures were elucidated by 1D and 2D NMR experiments including 1D TOCSY, DQF-COSY, ROESY, HSQC, and HMBC spectroscopy, as well as ESIMS analysis. The antiproliferative activity of all compounds was evaluated using three murine and human cancer cell lines: J774.A1, HEK-293, and WEHI-164.
