The extract is dried, evaporated to dryness, and the residue is dissolved in benzene and chromatographed. The eluate is then evaporated to dryness, the residue dissolved in absolute alcohol, treated with alcoholic hydrogen chloride, stripped down to dryness, and the glassy residue triturated with acetone to yield white crystals of the title compound, m.p. 249°-252°.
