New method of dosage multialkaloids!
PHYTOCONTROL has the pleasure to announce you that its R*D service recently developed a new innovative method by UFLC allowing the simultaneous dosage of the ergot alkaloids and the Datura alkaloids with limits of quantification from 1 to 5 µg/kg!
The term of ergot makes reference to the fungal structures of the Claviceps species which replace grains on the ears of cereal or the seeds of the inflorescences of grasses and show themselves by of wide sclérotes of dark color. This sclérotes contains various classes of alkaloids, the most important of which are the ergométrine, the ergotamine, the ergosine, the ergocristine, the ergocryptine and the ergocornine and their by-products – inines.
The recommendations EU published N°2012/154 15 Mars 2012 introduced the necessity of proceeding with chromatographic methods to look for the content of certain alkaloids of the ergot not only in cereal raw products but also in products based on cereals. According to the same recommendation, member states should look for, at least, the following alkaloids of ergot :
Concerning the alkaloids of the Datura, the AFSSA published on February 18th, 2009 a notice of the presence of atropine and scopolamine as undesirable substances in buckwheat flour for human consumption and the relevance threshold provisional proposed by the DGCCRF.
Datura (Datura stramonium L.) is an annual herbaceous plant of the Solanaceae family found in fields and producing tropane alkaloids whose main compounds are a mixture of atropine and scopolamine, which are substances with parasympatholytic effect.
In its opinion, AFSSA has set an action level of 100 mcg/kg in buckwheat flour for the sum of alkaloids Datura.
