从诺丽酵素中分离获得两个新的曲酸类化合物nonikojic A (1)和nonikojic B (2), 通过多种现代波谱技术确定了它们的化学结构. 并对这2个化合物进行了胰岛素抵抗HepG2细胞葡萄糖摄取的活性评价, 结果显示化合物12在50 μmol/L剂量下均可显著地促进胰岛素抵抗HepG2细胞的葡萄糖摄取, 从而改善胰岛素抵抗.

关键词: 诺丽酵素, 曲酸类化合物, 葡萄糖摄取, 胰岛素抵抗HepG2细胞

Two new kojic acids, nonikojics A and B (1 and 2), were obtained from the water soluble extract of the Noni juice, and their chemical structures were elucidated by comprehensive modern spectroscopic techniques. The effects on glucose uptake of two new compounds were evaluated in insulin-resistant HepG2 cells, and the results indicated that 1 and 2 significantly increased glucose uptake with doses of 50 μmol/L and thus improved insulin resistance.

Key words: Noni juice, kojic acids, glucose uptake, insulin-resistant HepG2 cells
