Abstract
In a survey of antifungal stress compounds induced by cupric chloride we found that leaves ofChenopodium album exuded a highly fungitoxic metabolite mucondialdehyde (trans-2,trans-4-hexadienedial), which was associated with 13-oxo-9,11-tridecadienoic acids (cis-9,trans-11 andtrans-9,trans-11 isomers) presumably resulting from β-scission of 13-hydroperoxy-octadecadi(tri)enoic acid. The biogenesis and role as a general defensive agent in plants are briefly discussed.

The suspension culture ofC. albus was raised from a callus initially dedifferentiated from the seedlings, and grown at 27°C on a shaker in 500-ml shaking flasks containing 250 ml of MS medium; (sucrose, 3%; kinetin, 0.1 ppm; and 2,4-D, 2 ppm). The cells cultured for 2 weeks were stressed by the addition of CuCl2 (1.5 mM) and another two days incubation, at which point the filtered medium was extracted to give stress metabolites.

The presence of mucondialdehyde was confirmed in the exudates from many plants stressed with a cupric chloride solution by TLC, TLC bioautography and/or GC-MS in comparison with an authentic compound. A further survey of stress compounds revealed that 6-hydroxy-trans-2,trans-4-hexadienal was produced byHypochoeris radicata L. (Compositae) in addition to mucondialdehyde. The results (Y. Maruta et al.) will be published elsewhere.
