methanol-water (65:35, v/v): (a) Untreated control; (b)
tumour tissue from a nude mouse treated with
DL-α-difluoromethylornithine (DFMO) for seven days
by oral administration (2% DMFO in drinking water)
plus intraperitoneal injection (500 mg/Kg). Benzoylated
putrescine (PU), 1,6-hexanediamine (internal standard,
IS), spermidine (SPD), spermine (SPM) were monitored
by their absorbance at 229 nm. [Reproduced

an RP-C8 column, a mobile phase of 40 mM CH COOH/NH OH (pH 5)-CH CN (10:90) and UV
3 4 3
detection at 254 nm is conducted.
