- 論文の詳細を見る
A new coumestan, tephcalostan (1) has been isolated from the whole plant of Tephrosia calophylla BEDD. together with two known flavonoids, 7-O-methylglabranin (2) and kaempferol 3-O-β-D-glucopyranoside (3). The structure of tephcalostan was elucidated as 5'-(R)-8,9-methylenedioxy-5'-isopropenyl-4',5'-dihydrofurano-[2',3' : 2,3] coumestan by extensive one-and two-dimensional (1D- and 2D-)-NMR techniques including ^1H-^1H correlation spectroscopy (COSY), heteronuclear single quantum coherence (HSQC), heteronuclear multiple bond connectivity (HMBC) and nuclear Overhauser enhancement spectroscopy (NOESY) experiments.
