  <name>28-Norbrassinolide</name>
  <description>28-norbrassinolide belongs to brassinolides and derivatives class of compounds. Those are cholestane based steroid lactones containing benzo[c]indeno[5,4-e]oxepin-3-one. 28-norbrassinolide is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 28-norbrassinolide can be found in tea and turnip, which makes 28-norbrassinolide a potential biomarker for the consumption of these food products. </description>
