title: Identification of antioxidant activity of two new aromatic ring butyrolactone derivatives from Dictamnus dasycarpus Turcz.
abstract: The present study carried out a phytochemical investigation on the root barks of Dictamnus dasycarpus Turcz, leading to the isolation and characterization of two new aromatic ring butyrolactone derivatives, dasycarpusphenol acid A (1) and dasycarpusphenol acid B (2). Their structures were elucidated by using spectroscopic techniques and HR-FAB-MS. Compounds 1 and 2 exhibited antioxidant activity, with their IC50values being 28.95 and 41.76 mg·mL-1, respectively.
