Radical scavenging activities of flavonoids from roots of Akschindlium godefroyanum.[Pubmed:
25426867 ]
METHODS AND RESULTS:
Chemical constituents of crude ethyl acetate extract of roots of Akschindlium godefroyanum (Kuntze) H. Ohashi were investigated and seven flavonoids were isolated. Their structures were identified based on spectroscopic methods as well as by comparison with spectral data reported in the literature as six flavanonols and a flavonol including 7,4'-dihydroxy-5,3'-dimethoxyflavanonol (1), Neophellamuretin (2), taxifolin (3), erycibenin D (4), geraldol (5), fustin (6) and garbanzol (7).
CONCLUSIONS:
Compounds 2, 4 and 7 were found in the genus Akschindlium for the first time. Compounds 3, 5 and 6 appeared to have free radical scavenging activities using DPPH assay with IC50 of 21, 40 and 15 μg/mL, respectively.
