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。 In order to study the chemical constituents in the leaves of Acacia atropurpureus, six compounds were isolated from the 95% ethanol extract of Anemarrhena asphodelus by silica gel, Sephadex LH-20, RP-C18 and other chromatographic methods. Resonance spectroscopy, mass spectrometry and other spectral analysis of compounds identified the structure. One of the new compounds is p-acetyl-phenol 1-O-β-D-xylopyranosyl- (1 → 2) -β-D-glucopyranoside (1) and five known compounds: piceine (2), isorhamnetin 3), quercetin (4), rutin (5) and isorhamnetin-3-rutinoside (6). Compounds 2-6 were isolated from leaf-free pseudobulb for the first time.
