假木贼中化学成分的分离和结构鉴定

目的研究盐生假木贼(Anabasis salsa)的正丁醇和短叶假木贼(Anabasis brevifolia)的氯仿提取物的化学成分。方法用LP-18及硅胶等色谱技术进行分离纯化，根据理化性质、光谱数据进行结构鉴定。结果得到5个化合物，分别鉴定为2-O-β-D-葡糖基-4，6-二甲氧基苯乙酮(1)，2-O-(2)-β-D-葡糖基-4,6-二甲氧基苯乙酮(2)，3-甲基-丁-2-烯酸-［2-(4-甲氧基苯基)-乙基］-酰胺(3)，5，6，7，2′-四甲氧基异黄酮(4)，2′-羟基-5，6，7-三甲氧基异黄酮(5)。结论化合物2,3,5为新化合物，其余化合物均为首次从假木贼属(Anabasis.L)植物中分离得到。

Isolation and structure identification of chemical constituents from Anabasis brevifolia

AIM: To study the chemical consitituents of the n-butanol-extracts of Anabasis salsa and Various chromatographic techniques were used to the chloroform-extract of Anabasis brevifolia. METHODS: separate and purify the constituents. Their physico-chemical properties and spectral data were used to elucidate their structures. RESULTS: Five compounds were isolated and identified as 2-O-beta-D-glucopyranosyloxy-4,6-dimethoxy phenylenthanone (1), 2-O-(2)-beta-D-glucopyranosyloxy-4, 6-dimethoxy phenylenthanone (2), 3-methyl-but-2-enoic acid-[2-(4-methoxy phenyl)-ethyl]-amide (3), 5,6,7,2'-tetramethoxy isoflavonoid (4), 2'-hydroxy-5,6,7-trimethoxyisoflavonoid (5). CONCLUSION: Compounds 2, 3, and 5 are new compounds. And the others were isolated from Anabasis L. for the first time.
