Two linear Annonaceous acetogenins, calamistrins H and I (1 and 2) were isolated from an ethanolic extract of the roots of Uvaria calamistrata Hance (Annonaceae) with silica gel column and preparative HPLC. Compounds 1 and 2 belong to a class of acetogenins without tetrahydrofuran (THF) ring on the chain. The structures of 1 and 2 were determined by spectroscopic analysis (NMR and MS) and chemical derivatives.
