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.
从毛果苔草种子中分离出两种新的酚类化合物、一种芪类化合物毛果苔草酚A（1）和一种查耳酮毛果苔草酚B（2），以及十种已知化合物（3 - 12）。基于高分辨电喷雾电离质谱（HRESIMS）、一维和二维核磁共振（NMR）数据等光谱分析方法阐明了化合物1 - 12的结构。对所有化合物进行了酪氨酸酶抑制活性评估。
