Metabolism of ¹⁴C-homodestruxin B (1), in leaves of plants R and S to A. brassicae

Species	Cultivar	% of homodestruxin B converted to hydroxyhomodestruxin B* tR = 21.5 min†
S. alba	Ochre (R)	>90% in 24 h
B. juncea	Cutlass (S)	10% in 24 h; 40% in 72 h
B. napus	Westar (S)	<10% in 72 h

^*Results are averages of experiments conducted in triplicate; percentage of conversion determined by HPLC analysis as described in Materials and Methods; areas of peaks determined in counts and converted to dpm utilizing a calibration curve; the total HPLC peak areas were within 10–20% of the LSC total counting. 

^† t_R = retention time of compounds detected in Radiomatic detector.
