Examinations were made on the sterol (needles, m.p. 138-139°, [α]D25-36° (CHCl3)), obtained from the non-saponifiable matter of the crude oil, produced in 1.0-1.2% yield from Pinellia ternata BREITENBACH (Japanese name “Hange”), and this was found to be β-sitosterol. This sterol is present in ca. 3.4-4.0% in the crude oil.
A quaternary base was separated from the methanol extract of this plant as the ammonium reineckate and the analysis of its picrate (yellow needles, m.p. 240-241°) corresponded to the molecular formula of C11H16O8N4. From the analytical values and properties of various derivatives, this base was proved to be choline.
Re-examination of Suzuki's experiment revealed that this crude drug did not contain any tertiary base which is said to be the antiemetic factor.
