Lupinus hispanicus

Lupinus luteus L., Lupinus hispanicus L., Lupinus hirsutus L. They have also been found in Anabasis aphyla. In absolute configuration, lupinine is in its (—)-form, which is non-stable thermally, and is easily epimerized to epilupinine, which is a stable (+)- form of lupinine . The melting point of (—)-lupinine is 70-71 °C, of mixed (+ and —)-lupinine 63-64°C, and of (+)-lupinine (synthetic)... 

The aerial parts of Lupinus hispanicus B. and R. (var. bicolor Merino) contain four alkaloids, of which three were identified as (+)-epilupinine, (—)-lupinine, and gramine. The fourth alkaloid (Alkaloid Y), an amorphous but apparently homogeneous base, was obtained in such small amounts that it has not yet proved possible to determine its structure.150...
