| Journal of Organic Chemistry, 1965, 30(7):2353-2355. | | Medicagol, a New Coumestan From Alfalfa.[Reference: WebLink] |
METHODS AND RESULTS:
A new coumestan, Medicagol(C16H8O6), has been identified in alfalfa. Characterization was accomplished by degradative and proton magnetic resonance (p.m.r.) studies.
CONCLUSIONS:
Synthesis confirmed the structure as 7-hydroxy-11,12-methyl-enedioxycoumestan, closely related to the antifungal agent, pisatin. | | Journal of Asian Natural Products Research, 2002, 4(1):1-5. | | A new Coumaronochromone from Sophora japonica.[Reference: WebLink] |
METHODS AND RESULTS:
A new coumaronochromone derivative, sophorophenolone (1), along with 13 known compounds, l-maackiain (2), Medicagol (3), 7-O-methylpseudobaptigenin (4), pseudobaptigenin (5), 7,3'-di-O-methylorobol (6), genistein (7), prunetin (8), daidzein (9), formononetin (10), Di-O-methyldaidzein (11), quercetin (12), kaempferol (13) and isorhamnetin (14) were isolated from pericarps of Sophorajaponica L.
CONCLUSIONS:
The structure of compound 1 was established by UV, IR, MS, and one-dimensional and two-dimensional NMR spectroscopy, including DEPT, NOESY, 1H-1H COSY, HMQC, and HMBC experiments. |
