概要

• 論文の詳細を見る

• The roots of Cynanchum wilfordi HEMSLEY were found to contain a glycoside mixture. The glycosides showed a positive Keller-Kiliani reaction, suggesting the presence of a 2-deoxysugar. The sugar portion of the glycoside was found to be D-cymarose. The aglycone was shown to be an ester. Alkaline hydrolysis of the ester aglycone afforded three kind of pregnane compounds, sarcostin (I), deacylcynanchogenin (II), and deacylmetaplexigenin (III). Cinnamic acid was found in the acidic fractions.
