Nine new neolignan glycosides (1–9), viburfordosides A–I, two new neolignans, fordianes A and B (10, 11), and seven known analogues (12–18) have been isolated and identified from the fruits of Viburnum fordiae Hance. The structures and absolute configurations of undescribed neolignan constituents were identified by chemical methods and spectroscopic analyses. The α-glucosidase inhibitory, ABTS•+ and
九个新新木脂素甙(1 - 9),viburfordosides A-I,两个新的新木脂体,fordianes A和B(10,11),和七个已知类似物(12 - 18)已被分离,并从果实识别荚fordiae昂斯。未描述的新木脂素成分的结构和绝对构型通过化学方法和光谱分析鉴定。α-葡萄糖苷酶抑制物ABTS •+和DPPH •对这些次生代谢产物的清除和抗炎活性进行了评估。它们中的一些在抑制α-葡糖苷酶和清除自由基方面显示出显着的效力。间被发现具有抑制NO产生的能力,所述14种代谢物LPS刺激的巨噬细胞的RAW264.7细胞中,化合物2,4,6,10,11,14,17,和18分别为有效的带IC 50个的值10.88 –41.10μM。这些结果支持V. fordiae 拥有新木脂素化合物的水果既可以作为功能食品,又可以作为预防和治疗2型糖尿病(T2D)的医学资源。
