Cipaferoids A–C,Three Limonoids Represent Two Different Scaffolds from Cipadessa baccifera

Three limonoids cipaferoids A–C ( 1 – 3 ) representing two different scaffolds were isolated from Cipadessa baccifera. Their structures were completely assigned by spectroscopic data, CD exciton chirality method, and X‐ray crystallography. Compounds 2 and 3 exhibited moderate antimalarial activity with IC₅₀ values of 9.3±0.1 and 14.7±4.8 μmol•L^–1, respectively.     

Secondary metabolites from the unique bamboo,Melocanna baccifera

Phytochemistry of fruits and leaves of the unique bamboo Melocanna baccifera resulted in the isolation of 27 secondary metabolites, including 4-Oxabicyclo[3.2.2]nona-1(7),5,8-triene and Verbacine. Biological activity studies of Verbacine revealed it as an inhibitor of acetylcholinesterase and as cytotoxic against C6 cancer cells.
