The plant Rhinopetalum korelini Fisch. (family Liliaceae) has not been studied chemically. We investigated the epigeal part collected on May 10, 1974, in the village of Babadurmez, Turkmen SSR, during the period of mass fruit bearing. A mixture of bases was extracted from the plant with chloroform. After appropriate working up, combined ether-soluble (0.07%) and chloroform-soluble (0.08%) alkaloids (amounting to 0.15% on the weight of the dry plant) were obtained. Through column chromatography (silica gel, alumina) and rechromatography, several alkaloids were isolated: alkaloid (II) was identified as solanidine (by mixed melting point and Rf), alkaloid (I) and (III) were confirmed as rhinoline and rhinolinine respectively (via study of hydrolysis products, comparison of IR spectra and melting points with known compounds). Thus, solanidine, rhinoline, and rhinolinine have been isolated for the first time from Rhinopetalum korelini.
