RESUMO
Objective: To study the chemical constituents from the aerial parts of Anabasis aphylla. Methods: The chemical constituents were isolated and purified by silica gel column, Sephadex LH-20, prep-TLC, and prep-HPLC. Spectroscopic methods, such as MS, IR, and NMR spectra were used for the structural identification. Results: Fifteen compounds were isolated and identified as: eicosyl-(Z)-caffeate (1), eicosyl-(E)-caffeate (2), trydecyl-(E)-caffeate (3), hexadecyl-(E)-caffeate (4), octadecyl-(E)-caffeate (5), docosyl-(E)-caffeate (6), tetracosyl-(E)-caffeate (7), eicosyl-(E)-ferulate (8), docosyl-(E)-ferulate (9), tetracosyl-(E)-ferulate (10), 4-hydroxyacetophen-one (11), n-tridecanoic acid (12), n-myristic acid (13), daucosterol (14), and β-sitosterol (15). Conclusion: Compound 1 is a new compound, and compounds 2-13 are isolated from the plants in Anabasis L. for the first time.
