• 論文の詳細を見る

• Two new flavanones, I and VII, and daidzein were isolated from Guang-Dou-Gen (the root of Sophora subprostrata CHUN et T.CHEN). Fom the spectral data and comparison with sophoranochromene and its derivative, the structure of I was established as 2-[{3'-hydroxy-2', 2'-dimethyl-8'-(3-methyl-2-butenyl)} chroman-6'-yl]-7-hydroxy-8-(3-methyl-2-butenyl) chroman-4-one. The structure of VII was formulated from the spectral data and biogenetic speculation as 2-[{2'-(1-hydroxy-1-methylethyl)-7'-(3-methyl-2-butenyl)-2'3'-dihydrobenzofuran}-5'-yl]-7-hydroxy-8-(3-mehtyl-2-butenyl) chroman-4-one.
