A new meroterpene, psoracorylifol F (1), was isolated from Psoralea corylifolia fruits, along with two known meroterpenes (2 and 3), guided by TLC bioautography against O(2)(-) radicals. The structure of 1 was elucidated by means of NMR, HRESIMS, and X-ray crystallographic analysis. All the three metroterpenes possessed potential inhibitory activity against LPS-induced NO production in RAW 264.7 cells with IC(50) values ranging from 7.71 to 27.63μM.
从补骨脂果实中分离得到一个新的倍半萜类化合物，psoracorylifol F（1），并通过 TLC 生物自显影法对抗 O(2)(-)自由基，从补骨脂中分离得到两个已知的倍半萜类化合物（2 和 3）。通过 NMR、HRESIMS 和 X 射线晶体学分析阐明了 1 的结构。所有三种代谢萜类化合物均具有潜在的抑制 LPS 诱导的 RAW 264.7 细胞中 NO 产生的活性，IC(50)值范围为 7.71 至 27.63μM。
