  <name>Pretazettine</name>
  <description>Pretazettine, also known as pretazettine hydrochloride, (6abeta,8beta)-isomer, is a member of the class of compounds known as tazettine-type amaryllidaceae alkaloids. Tazettine-type amaryllidaceae alkaloids are amaryllidaceae alkaloids derived from the haemanthamine-type alkaloids, which are characterized as a linkage between C6 and C11 by an oxygen atom to form a [3,4-g]benzopyran framework. Pretazettine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Pretazettine can be found in lovage, which makes pretazettine a potential biomarker for the consumption of this food product.</description>
