In our continuation of exploring antidiabetic agents from species, we found that the methanolic extract of A.C.Sm. exhibited considerable α-glucosidase inhibition of 58.20 ± 0.37% in sucrose substrate and 39.86 ± 2.07% in maltose substrate at 100 μg/mL. Phytochemical investigation on the extract revealed the presence of a new biphenyl, macrabiphenyl A, which was successfully elucidated by means of spectroscopic methods (HRESIMS and 1D and 2D NMR). The α-glucosidase inhibitory evaluation indicated that the new compound was weakly active against the enzyme.
在我们继续从 物种中寻找抗糖尿病药物的过程中，我们发现 A.C.Sm. 的甲醇提取物在 100μg/mL 时对蔗糖底物表现出相当大的α-葡萄糖苷酶抑制作用，为 58.20±0.37%，对麦芽糖底物的抑制作用为 39.86±2.07%。对提取物的植物化学研究表明存在一种新的联苯，即 macrabiphenyl A，通过光谱方法（HRESIMS 和 1D 和 2D NMR）成功阐明了该化合物。α-葡萄糖苷酶抑制评估表明，新化合物对该酶的活性较弱。
