Five new compounds, including four C(17) gamma-lactones, dihydroisoobtusilactone (1), dihydroobtusilactone (2), 3-epilitsenolide D(2) (3), and 3-epilitsenolide D(1) (4), and one furanone alseodafuranone (5), were isolated from the root and stem of Alseodaphne andersonii. Their structures were elucidated mainly by spectral analysis (NMR and MS) and partially by chemical correlation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
