Abstract
Five new annonaceous acetogenins, calamistrins C-G (1-5), were isolated fro m an ethanolic extract of the roots of Uvaria calamistrata. Compounds 1-3 w ere mono-THF ring acetogenins; compounds 4 and 5 were bis-THF acetogenins, with the THF rings from C-18 to C-25. The absolute configurations of 3, 4, and 5 as well as the partial absolute configurations of 1 and 2 were determ ined by C-13 NMR spectroscopy and advanced Mosher methodology.
