  <name>Charantin</name>
  <description>Charantin, also known as naftidrofuryl or nafronyl, is a member of the class of compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Charantin is practically insoluble (in water) and a very strong basic compound (based on its pKa). Charantin can be found in bitter gourd, which makes charantin a potential biomarker for the consumption of this food product. Charantin is actually a 1:1 mixture of two steroidal saponins, β-sitosteryl glucoside (C 35H 60O 6) and 5,25-stigmasteryl glucoside (C 35H 58O 6). It is a whitish crystalline substance, neutral and tasteless, melting at 266–268 °C. It is sparingly soluble in water or other highly polar solvents, as well as in apolar solvents like hexane, but is soluble in ether, ethanol and methanol, and can be efficiently extracted from the plant by pressurized ethanol or acetone at 100 °C .</description>
