Phenolic constituents of Carex vulpinoidea seeds and their tyrosinase inhibitory activities

Nat Prod Commun. 2015 Mar;10(3):491-3.

Abstract

Two new phenolics, a stilbenoid, vulpinoideol A (1), and a chalcone, vulpinoideol B (2), along with ten known compounds (3-12) were isolated from Carex vulpinoidea Michx. seeds. The structures of compounds 1-12 were elucidated based on spectrometric and spectroscopic analyses including HRESIMS, 1D and 2D NMR data. All compounds were evaluated for their tyrosinase enzyme inhibitory activities.
