无叶假木贼的化学成分研究(英文)

Studies on the chemical constituents of Anabasis aphylla L.

摘要:
为了研究无叶假木贼中的化学成分, 采用硅胶、Sephadex LH-20、RP-C₁₈等色谱方法分离纯化, 从无叶假木贼的95%乙醇提取物中分离到6个化合物, 通过核磁共振谱、质谱等波谱分析手段鉴定化合物结构。其中包括1个新化合物: p-acetyl-phenol 1-O-β-D-xylopyranosyl-(1→2)-β-D-glucopyranoside (1) 和5个已知化合物: piceine (2)、isorhamnetin (3)、quercetin (4)、rutin (5) 和isorhamnetin-3-rutinoside (6)。化合物2 – 6均为首次从无叶假木贼中分离得到。

Abstract:
The investigation on the chemical constituents of Anabasis aphylla L. was carried out by using various chromatographies, such as silica gel, Sephadex LH-20 and RP-C₁₈ column chromatography. Further detailed investigation on the fraction of the ethanol extract of Anabasis aphylla L. yielded one new compound p-acetyl-phenol 1-O-β-D-xylopyranosyl-(1→2)-β-D-glucopyranoside (1), together with five known compounds: piceine (2), isorhamnetin (3), quercetin (4), rutin (5) and isorhamnetin-3-rutinoside (6). Their structures were elucidated by spectral analysis such as NMR and MS. Among these compounds, compounds 2 – 6 were isolated from this plant for the first time.
