目的:研究博落回根中的生物碱成分。方法:采用硅胶柱色谱、重结晶、半制备液相色谱制备化合物,利用NMR、MS等波谱技术鉴定化合物结构。结果:从博落回根的乙醇提取物中分离得到9个生物碱类化合物,分别为二氢白屈菜红碱(1),6-氰基二氢血根碱(2),R-6-((R)-1-hydroxyethyl)dihydrochelerythrine(3),碎叶紫堇碱(4),四氢小檗碱(5),8-去甲基二氢白屈菜红碱(6),8-去甲基白区菜红碱(7),原阿片碱(8),别隐品碱(9)。结论:化合物4~6首次在博落回属植物中分离得到。
Objective: To study the alkaloids composition Methods: The compounds were prepared by silica gel column chromatography, recrystallization and semi-preparative liquid chromatography. Their structures were identified by NMR, MS and other spectroscopic techniques. Results: Nine alkaloids were isolated from the ethanol extracts of Plutella xylostella, which were dihydroquercetin (1), 6-cyanohydrin (2), R-6 - ((R) -1-hydroxyethyl) dihydrochelerythrine (3), Corydaline (4), Tetrahydroberberine (5), 8-Desmethyl dihydroquercetin (6), 8 - Demethyl white zone Caihong base (7), the original opium alkali (8), not hidden alkali (9). Conclusion: Compounds 4 ~ 6 were isolated from Botanicum genus for the first time.
