8β,10β-Epoxy-3,7,8-trimethoxyhasubanan-4,6β-diol 6-[(E)-3-(3-hydroxy-4-methoxyphenyl)propenoate]

This alkaloid occurs in Stephania hernandifolia Walp. It is obtained as an amorphous white pwoder which forms a crystalline adduct with CHCI3 having m.p. 227-227.5°C. The alkaloid is optically active with a specific rotation of [α]_D - 25° (c 2.0, EtOH) and yields a diacetate as colourless crystals from C6H6-Et 20 with m.p. 171-171.5°C. The structure has been elucidated from chemical and spectroscopic analysis.
