(Annonaceae), a Vietnamese folk medicinal plant, the novel type natural products fissistigmatin A–D (1–4), being composed of a flavonoid and a sesquiterpene moiety, were isolated. Their structures were elucidated by extensive NMR techniques, MS, CD, molecular modelling calculations and X-ray analysis. A2 - C1 - Bioorganic Chemistry ER -
