title: Stilbenoids from Stemona sessilifolia.
abstract: Two new dihydrostilbenes, stilbostemins H (1), I (2), and a new dihydrophenanthrene, stemanthrene E (3), were isolated and identified from the roots of Stemona sessilifolia, together with known stilbostemins B, D and G, and stemanthrenes A and C (4-8). Structures of new stilbenoids were established by 1D and 2D (1)H NMR and (13)C NMR spectroscopic analyses.
