Bioactive minor components of the hexane extract of Desmodium canum root have been assigned the new structures 2 – 7 of complex isoflavans. Four of them contain the 6‐methyl group typical of the major isoflavanone plant constituents and were named desmodians A–C and 3′‐hydroxydesmodian C, the others being 6‐desmethyldesmodians A and B. All of the isoflavans except 6 (with a 5‐OH group) carry a quite rare 5‐OMe substituent. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
