This base was first prepared synthetically by Partheil and subsequently discovered in the roots of Caulophyllurn thalictroides L. It is widespread among the Papilionaceae, being found in Baptisia australis, Genista tinctoria, Sophora microphylla, S. tetraptera, Thermopsis lanceolata and T. rhombifolia (Watt.) Richards. It is laevorotatory with [α]²⁰_D - 221 ° (H20) and furnishes the following crystalline salts and derivatives: hydrochloride, m.p. 2S0-SoC (dec.); hydriodide, m.p. 246-7°C (dec.); perchlorate, m.p. 2S4°C (dec.); aurichloride, m.p. 206°C (dec.); picrate, m.p. 230°C; picrolonate, m.p. 224-SoC (dec.) and the methiodide which occurs in two modifications, m.p. 248°C and 267-276°C.
