  <name>Osthol</name>
  <description>Osthol, also known as 7-methoxy-8-(3-methylpent-2-enyl)coumarin, belongs to coumarins and derivatives class of compounds. Those are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Osthol is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Osthol can be found in a number of food items such as wild celery, lemon, parsley, and wild carrot, which makes osthol a potential biomarker for the consumption of these food products. Osthol is an O-methylated coumarin. It is a calcium channel blocker, found in plants such as Cnidium monnieri, Angelica archangelica and Angelica pubescens .</description>
