4-(1,2,3,5,8,8a-Hexahydro-7-methylindolizin-6-yl)phenyl β-D-glucopyranoside 6-[3-(4-hydroxyphenyl)propenoate]

Ipomoea muricata yields this glycoalkaloid. It forms an amorphous solid from Et20 having a fairly sharp melting point. The base is dextrorotatory with a specific rotation of [α]D +46.4° (CHCI3) and gives an ultraviolet spectrum in EtOH with absorption maxima at 232 and 315 nm. lpomine has been characterized as the picrate, m.p. 138-141°C.
