Two new lignans (1-2) and a new octaketide (12), together with twenty-nine known compounds (3-11, 13-32) were isolated and identified from the aerial part of Pogostemon cablin. Their chemical structures were revealed mainly through NMR and MS data. The absolute configuration of 1 and 2 was deduced by comparing its experimental CD with the calculated ECD spectra. The inhibitory activities of the isolated compounds on LPS-stimulated nitric oxide (NO) production in RAW 264.7 cells were investigated. At a concentration of 25 μM, compounds 1 and 11 showed approximately equal NO inhibitory effects to that of aminoguanidine.
从广藿香地上部分分离得到两个新的木脂素(1-2)和一个新的八聚体(12),以及 29 个已知化合物(3-11,13-32)。它们的化学结构主要通过 NMR 和 MS 数据揭示。通过比较其实验 CD 与计算 ECD 光谱,推断出 1 和 2 的绝对构型。对分离得到的化合物在 LPS 刺激 RAW 264.7 细胞中一氧化氮(NO)产生的抑制活性进行了研究。在 25 μM 浓度下,化合物 1 和 11 对 NO 的抑制作用与氨基胍相当。
