文冠果果壳中一个新生物碱

A new alkaloid from the husk of Xanthoceras sorbifolia

摘要: 目的研究文冠果果壳的化学成分。方法通过硅胶柱色谱、制备型薄层色谱进行化合物的分离，利用多种波谱技术鉴定化合物结构。结果分离得到10个化合物，鉴定为：2-甲基-6-(2′，3′，4′-三羟基丁基)吡嗪(I)、cleomiscosin D(II)、柚皮素(III)、圣草素(IV)、山柰酚(V)、槲皮素(VI)、芦丁(VII)、5，7-二羟基色原酮(VIII)、酪醇(IX)、1-O-甲基-肌-肌醇(X)。结论化合物I为一新化合物；化合物II，IV，V和VII～X均为首次从该属植物中分离得到。

Abstract: AimTo study the chemical constituents from the husk of Xanthoceras sorbifolia Bunge. MethodsRepeated column chromatography on silica gel and preparative TLC were used to isolate the compounds whose structures were elucidated based on spectroscopic data (ESIMS, EIMS, 1D and 2D NMR). ResultsA new alkaloid was isolated and identified as: 2-methyl-6-(2′,3′,4′-trihydroxybutyl)-pyrazine (I), along with nine known compounds: cleomiscosin D (II), naringenin (III), eriodictyol (IV), kaempferol (V), quercetin (VI), rutin (VII), 5,7-dihydroxychromone (VIII), tyrosol (IX), 1-O-methyl-myo-inositol (X). ConclusionCompound I is a new alkaloid, compounds II, IV, V, VII-X were isolated from this genus for the first time.
