Abstract
From the hypocotyl of scarlet runner bean (Phaseolus coccineus), a new 2,3-dihydro-2,5-dihydroxy-6-methyl-4H-pyran-4-one conjugated saponin, named soyasaponin alpha a, was isolated together with two known sapon ins, soyasaponin alpha g and beta g. Their structures were elucidated by H-1 NMR and (13)CNMR spectroscopy and chemical techniques.
