[A new medicinal plant Pterocapus indicus].
It has been 70 years since Ptercapus indicus Willd. was introduced into China. The red sap from its incision of the bark becomes a kind of red crystal after some hours of exposure to air, which is used as an astringent and against other diseases. Its physicochemical properties, elements and amino acids have been analysed. The structural analysis shows that the crystal is a macromolecular compound of tannic condensation and glucoside.
