Isolation and Identification of Antioxidant Flavonoids from the Seeds of Cardiocrinum Giganteum var. Yunnanense
Journal Title: Journal of Pharmaceutical and Biomedical Sciences - Year 2016, Vol 6, Issue 6
Abstract
One new biflavonoid, 3″-hydroxyrobustaflavone (1), together with four known compounds (2-5) were isolated from the seeds of Cardiocrinum giganteum var. yunnanense. The new structure was elucidated based on the extensive spectroscopic methods and the known compounds were identified by comparison with the literatures. In addition, all of these isolated compounds possessed good antioxidant capacities beyond that of L-ascorbic acid.
