Renchangianins F and G: two new sesquiterpenoids from Kadsura renchangiana.

Phytochemical investigation on the stems ofKadsura renchangianaled to the isolation of two new sesquiterpenoids, renchangianins F and G (1and2). Their structures were elucidated by spectroscopic methods, including 2D NMR techniques. Thein vitrocytotoxic activities of the isolates were studied against HepG2, A549, and LN229 cancer cell lines.
