Separation of the extract of the underground tubers of Cyperus conglomeratus Rottb. (family Cyperaceae) afforded, in addition to known compounds, two novel flavans, which were identified, by one and two dimensional NMR, MS and IR spectra, as 5-hydroxy-7,3',5'-trimethoxyflavan and 5,7-dihydroxy-3',5'-dimethoxy-6-prenylflavan.
