Studies on the chemical constituents of Anabasis aphylla L.

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.
