托里贝母(Fritillaria tortifolla X .Z.Duan et X.J.Zheng)为百合科贝母属植物,产于新疆塔城一带,民间用以代替伊贝,具有化痰止咳,清热散结等功效。此原料采自新疆裕民县贝母试验站,系野生品人工引种栽培。品种经中国科学院新疆沙漠土壤高原生物研究所刘国钧教授鉴定。我们从其鳞茎中分得5个生物碱成分,其中一个新生物碱命名为托贝辛(Tortifolisine,1);另4个已知成分分别鉴定为西贝素(Imperialine,2)、茄次碱(Solanidine,3)、(Delavinone,4)和Tortifoline(5)。应用谱学技术确定了新生物碱的结构,并归属了其C NMR的信号。 Fritillaria tortifolla X.Z.Duan et X.J.Zheng is a Liliaceae Fritillaria genus, produced in the Tacheng area of ​​Xinjiang, folk to replace the Iberian, with the functions of Huatanzhike, heat Sanjie. This material was collected from the Fritillaria Yumin County Experimental Station, Department of artificial introduction of wild cultivation. Species by the Chinese Academy of Sciences Xinjiang desert plateau Institute of Biology Professor Liu Guojun identification. We isolated five alkaloids from their bulbs, one of which was named Tortifolisine (1) and the other four known components were identified as Imperialine (2) (Solanidine, 3), (Delavinone, 4) and Tortifoline (5). The structure of neo-alkaloids was identified using spectroscopy techniques and assigned to their C NMR signals.
