Biodegradation of 6-methyl-2,3-dithiolquinoxaline cyclocarbonate or quinomethionate (Q1) by cucumber seedlings seems to confirm that the thiocarbonate linkage is disrupted during metabolism of the fungicide by the plant.The sulfur liberated is principally incorporated into sulphates and sulfur amino-acids, while the labeled (2,3-14C) quinoxaline nucleus is catabolized to 14CO2. This work also suggests that microorganisms can largely share in fungicide biodegradation when they are in the immediate environment of seedlings.
Preparation of two ion-pair complexes of 3-dl-?-tocopherylcarbonyl-1-hexyl-pyridinium-[14C]-labeled cromolyn and 3-d-?-[5-methyl-3H] tocopherylcarbonyl-1-hexylpyridinium-cromolyn
Ion-pair complexes of 3-dl-alpha-tocopherylcarbonyl-1-hexyl pyridinium-[C-14]-labeled cromolyn and 3-d-alpha-[5-methyl-H-3] tocopherylcarbonyl-1-hexylpyridinium-cromolyn have been prepared with radiochemical yields of 56.0 and 65.7 %, respectively.
