oleandrigenin, and others. Preparations of oleander are used for cancer treat-
ment. Oleandrin, odoroside, neritaloside, and the aglycone oleandrigenin,
present in the extract of Nerium oleander (Anvirzel), were analyzed with
qTOF/MS. CID mass spectra were obtained with mass accuracy greater than
5 ppm. LOD for oleandrin was 20 pg injected. The method was applied for
the determination of oleander glycosides in human plasma after intramus-
173
cular injection of Anvirzel. A 45-year-old female took Nerium oleander for
suicidal purposes, showing nausea, vomiting, cardiovascular shock, and sinus
bradycardia. Oleandrin was measured in plasma at 1.1 mg/l and was also
175
174
identified in urine using ESI/LC/MS. Arao et al. applied SSI/LC/MS/MS
(ion trap) for determination of oleandrin, oleandrigenin, and desacetylole-
andrin in the heart, blood, and cerebrospinal fluid in the case of a fatal
suicidal poisoning of a 49-year-old woman who learned about oleander
toxicity on TV. Only oleandrin was found in concentrations of 9.8 and 10.1
mg/l in her heart, blood, and cerebrospinal fluid, respectively.
Capsaicinoids — capsaicin, dihydrocapsaicin, and nonivamide — occur
naturally in red pepper (Capsicum annuum). Due to its extremely irritative
properties, pepper spray is used in self-defense weapons, which are also
applied in criminal acts. Reilly et al. developed a LC/ESI/MS/MS procedure
for the determination of capsaicin, dihydrocapsaicin, and nonivamide in self-
177
176
defense weapons and in blood and tissue of experimental animals. The
LOQ in the latter procedure was 1 mg/l.
Ricin is a toxic protein (mol. wt. over 60,000 Da) present in the seeds of
castor beans (Ricinus communis L). This compound has a history of murder-
178
ous application and appeared in terrorist handbooks. Darby et al. analyzed
ricin and its marker ricinine in acetone extract of castor bean and in trypsin
hydrolysates. LC/UV, ESI/LC/MS, and MALDI/TOF/MS were applied. The
last technique gave the best results, both for intact ricin molecule and for
digested peptide fragments.
Colchicine, an alkaloid present in flowers of the autumn crocus (Colchi-
cum autumnale) has been used for centuries for the treatment of gout. Due
180
to its toxicity, several fatal cases were reported. Tracqui et al. extracted
179
colchicine from blood, plasma, or urine with dichlormethane at pH 8 and
determined with LC/ESI/MS in full scan and SIM mode. The LOD in SIM
181
mode was 0.6 mg/l. Jones et al. detected colchicine in the biofluids and
organs of a 73-year-old man who died 18 h after receiving a 1 mg intravenous
dose of colchicine. He was treated with oral colchicine in previous days.
Dichloromethane extraction, followed by LC/ESI/MS, was applied. The con-
centrations found were 50 mg/l in cardiac blood, 575 mg/l in liver, and 12,000
mg/l in bile.
Maurer et al. determined a- and b-amanitine in the urine of patients
182
intoxicated with Amanita mushrooms. The toxins were isolated with immu-
