Abstract: A new anthraquinone, hemerocal (V) along with other four anthraquinones (chryso- phanol, 2-methoxy-obtusifolin, obtusifolin and aloe-emodin) have been isolated from the ethanol extract of the roots of Hemerocallis citrina Baroni. The structure of hemerocal, as 2, 8-dihydroxy-l-methoxy-3-hydroxymethyl-9, 10-anthraquinone, has been established on the basis of spectral evidences, as well as confirmed by chemical reactions. We have in addition studied the 13C NMR of hemerocal and primary assignments of all carbons have been made by utilising the data documented for related compounds.
