摘要
In addition to luteolin and its 7-methyl ether, the CH2Cl2-MeOH (1:1) extract of Cyperus conglomeratus afforded two new prenylflavans identified as 7,3'-dihydroxy-5,5'-dimethoxy-8-prenylflavan and 5,7,3'-trihydroxy-5'-methoxy-8-prenylflavan. The structures were established by CIMS, H-1-NMR, C-13-NMR, H-H COSY, HMQC, HMBC and DEPT analysis. (c) 2005 Elsevier B.V. All rights reserved.
