Popis:	In addition to luteolin and its 7-methyl ether, the CH 2 Cl 2 –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, 1 H-NMR, 13 C-NMR, H-H COSY, HMQC, HMBC and DEPT analysis.
