Abstract

ABSTRACT: One novel monoterpene rhamnoside (1 ) and 7 known monoterpenes (2-8 ) were isolated from the ethanol extract of Cynanchum atratum for the first time. Their structures were identified by comprehensive spectroscopic data analysis such as nuclear magnetic resonance, high-resolution electrospray ionization mass spectra, optical rotatory dispersion, and acid hydrolysis. In the subsequent antioxidant assay, compound 8 exhibited obvious 2, 2-diphenyl-2-picrylhydrazyl hydrate radical scavenging activity. Graphical Abstract:
