This alkaloid has been found in both Veratrum album and V. viride Ait. It crystallizes from EtOH in hexagonal tablets and has [α]²⁰_D - 139° (CHC13). The hydrochloride dihydrate has m.p. 254-6°C (dry, dec.); the sulphate is also crystalline but the aurichloride is amorphous. Poethke has shown that the alkaloid is a secondary base, gives a nitro so derivative, m.p. 261°C, and contains five replaceable hydrogen atoms. On boiling with dilute HCl it is hydrolyzed to (+)- glucose and isojervine, an isomer of jervine. This latter base crystallizes with solvent, e.g. the CHC13 adduct softens at 135-1500 C; the crystallizate with EtOH has m.p. 114-6°C (dec.) and that with Me2CO has m.p. 110-4°C; [α]²⁰_D - 32° (EtOH).

ChEBI: Pseudojervine is a steroid saponin.
