    Journal: Zhongguo Zhong Yao Za Zhi; 2000 Mar; 25(3):159-60. PubMed ID: 12212098.
    Abstract:
    OBJECTIVE: To study the chemical constituents of Dioscorea bulbifera. METHOD: Column chromatography with silica gel was employed for the isolation and purification of constituents. The structures were elucidated by UV, IR, MS, 1H NMR and 13C NMR analyses. RESULT: Three compounds were obtained and elucidated as 3,7-dimethoxy-5,4'-dihydroxyflavone; 3,7-dimethoxy-5,3',4'-trihydroxyflavone and emodin. CONCLUSION: These compounds were separated from D. bulbifera for the first time.
