L. Leyssens et al., Interference of Helix pomatia extracts on the determination of methandriolin veterinary residue control analysis, ANALYST, 123(12), 1998, pp. 2643-2644
Aqueous solutions containing methandriol (MAD) were incubated with Succus h
elix pomatia (SHP) or beta-glucuronidase from Escherichia coli (EC). SHP, u
sed for enzymatic hydrolysis of urinary steroid conjugates for residue anal
ysis of anabolic agents, caused transformation of MAD into methyltestostero
ne. No conversion occurred when bacterial beta-glucuronidase from E. coli w
as used.
