Abstract
The utilisation of NMR fingerprinting is proposed as a rapid, available and reliable method to determine the contamination of herbal products. The presence of nimesulide has been reported recently as the contaminant of P.C. 28 Plus, a product based on herbal drugs marketed by the Italian company Cosval. The presence of the substance, as well as its relevant concentration (5%), was first reported by HPLC/MS analysis by other authors. The use of an NMR fingerprint confirmed the previous contamination with nimesulide in P.C. 28 Plus. The same contaminant was also found in P.C. 28 Pink. Furthermore, an analysis of Alergix Plus, another product of the same factory, evidenced the presence of bromhexin. © 2010 Taylor & Francis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
