E. Larsen et Lp. Christensen, Simple method for large scale isolation of the cyclic arylhydroxamic acid DIMBOA from maize (Zea mays L.), J AGR FOOD, 48(6), 2000, pp. 2556-2558
The 2-beta-O-D-glucoside of the cyclic arylhydroxamic acid 2,4-dihydroxy-7-
methoxy-2H-1,4-benzoxazin- 3(4H)-one (DIMBOA) that occurs in large amounts
in young maize shoots (Zea mays L.) is converted enzymatically to its aglyc
one upon tissue damage. The aglycone DIMBOA possesses strong biologically a
ctivity toward various organisms whereas the glucoside is almost biological
ly inactive. A simple procedure yielding DIMBOA in gram quantities, from 7-
day-old maize seedlings, was developed by using solid-phase extraction.
