Chemical constituents from Achillea alpina / 中草药

ABSTRACT

Objective: To investigate the chemical constituents from the aerial parts of Achillea alpina. Methods: The compounds were isolated and purified by various chromatographic techniques and their structures were characterized on the basis of physicochemical properties and their spectral analyses. Results: Eleven compounds were isolated. Their structures were identified as epifriedelanol (1), spinasterol (2), β-sitosterol (3), 5, 6-epoxy-24(R)-methylcholesta-7, 22-dien-3β-ol (4), β-daucosterol (5), schensianol A (6), negunfurol (7), (3S, 5S, 8R)-3, 5-dihydroxymegastigma-6, 7-dien-9-one (8), saropeptate (9), (+)-syringaresinol (10), and (±)-lariciresinol (11). Conclusion: All the compounds are isolated from the aerial parts of A. alpina for the first time, and compounds 1, 2, 4, 6-11 are reported to obtain from the plants in Achillea L. for the first time.
