Summary 1. The epigeal part ofThermopsis alterniflora at the beginning of flowering contains 3.35% of combined alkaloids. The separation of the combined bases yielded cytisine, N-methylcytisine, pachycarpine, thermopsine, and the new alkaloid alteramine.2. The structure of 11-allyl-N-methylcytisine has been established for alteramine.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.

The chromatographic properties of a SCOT capillary column with the Aerosil modified with a nematic liquid crystal of 4-methoxy-4′-ethoxyazoxybenzene were studied. The Rohrschneider constants and retention factors were determined for substances from various classes. The microheterogeneous adsorbent SCOT(SiO2 + MEAB) belongs to medium-polarity stationary phases by its selectivity. It was shown that, in the temperature range 95–110°C, the studied column possessed high values of para-meta selectivity, efficiency, and capacity with respect to arenes and polar substances. Examples of rapid separations of mixtures containing isomers of different types are presented. 相似文献
