  Endecaphyllacin is either of two similar compounds found in certain plants, such as Hemsleya endecaphylla.
  
  * Endecaphyllacin A, 2β-hydroxy-20,21,22,23,24,25,26,27-octanorcucurbita-5-ene-3,11,16-trione, C $_{22}H$ $_{30}O$ $_4.$ Crystallizes with 1 molecule of methanol as colorless prisms, mp 207-209 $°C;^{:1}$
  * Endecaphyllacin B, 2-hydroxy-20,21,22,23,24,25,26,27-octanorcucurbita-1,5-dien-3,11,16-trione, C $_{22}H$ $_{28}O$ $_4.$ It is the aglycon of khekadaengoside L from Trichosanthes tricuspidata. Crystallizes from methanol as colorless prisms, mp 229-231 $°C^{:2}$
  
  Endecaphyllacins A and B can be extracted from the dried tubers of Hemsleya endecaphylla with methanol, at concentrations 150 mg/72 g and 20 mg/72 g.
