title: Studies on the chemical constituents of Anabasis aphylla L.
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-beta-D-xylopyranosyl-(1-->2)-beta-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.
