Six new polyisoprenyl benzophenonoids, (+/-)-garcinialiptone A (1, 2), garcinialiptone B (3), (-)-cycloxanthochymol (4), garcinialiptone C (5), and garcinialiptone D (6), along with three known compounds, xanthochymol (7), isoxanthochymol (8), and cycloxanthochymol (9), were isolated from the fruits of Garcinia subelliptica. The structures of 1-6 were elucidated by spectroscopic analysis. Biological evaluation showed that all compounds 1-9 exhibited cytotoxic activity against a small panel of human tumor cell lines (A549, DU145, KB, vincristine-resistant KB).
从余甘子 Garcinia subelliptica 的果实中分离得到 6 个新的多异戊烯基二苯甲酮类化合物(±)-garcinialiptone A(1、2)、garcinialiptone B(3)、(-)-cycloxanthochymol(4)、garcinialiptone C(5)和 garcinialiptone D(6),以及 3 个已知化合物黄烷醇(7)、异黄烷醇(8)和环黄烷醇(9)。通过光谱分析阐明了 1-6 的结构。生物活性评价表明,所有化合物 1-9 对一组人肿瘤细胞系(A549、DU145、KB、长春新碱耐药 KB)均具有细胞毒性活性。
