| الوصف: | A new homoisoflavanone, (3 R)-5,7-dihydroxy-8-methyl-3-(2′-hydroxy-4′-methoxybenzyl)-chroman-4-one (1), was isolated from the 95% ethanol extract of the rhizomes of Polygonatum cyrtonema. The structure of 1 was determined by spectroscopic methods, especially 2D NMR techniques. Quantum chemical TD DFT calculations of the theoretical ECD spectrum of 1 allowed assignment of the absolute configuration as 3R. |
