Five kinds of bufadienolide shown in Chart 1 were analyzed by gas chromatography of trimethyl silyl ethers on a packed column of SE-30 (1.5%) at 235°. Their retention time and chromatogram are shown in Table I and Fig. 1. After simple pretreatment by column chromatography on alumina, cinobufagin content of Ch'an Su (Chinese drug, Tô-Senso) was estimated by gas chromatography as 7.2±0.2%.
γ-Sitosterol previously isolated from hexane-soluble part of Ch'an Su extract was shown to be a mixed crystal comprising of cholesterol, campesterol, and β-sitosterol, from the result of gas chromatograph and infrared spectral measurement.
