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) |
