从中药山香圆叶90%甲醇提取物中分离并鉴定得到22个萜类化合物,其中山香圆甲酸(1)和山香圆乙酸(2)分别为C-17降碳型松香烷型和半日花烷型二萜类新化合物。它们的结构是通过质谱、一维/二维核磁共振谱和圆二色谱(ECD)等波谱和光谱技术得以确定。化合物4、7、8、10-14、16-20和22均系首次从山香圆叶植物中分离得到。以细菌脂多糖(Lipopolysaccharide, LPS)刺激的小鼠单核巨噬细胞RAW264.7为模型,对所分离得到化合物的体外抗炎作用进行了评估,结果显示齐墩果烷型三萜类化合物坡模酸(pomolic acid, 19)和3β-顺式-对香豆酰氧基-2α,23-二羟基-齐墩果酸(3-cis-p-coumaroyloxy-2,23-dihydroxyolean-12-en-28-oicacid, 22)在LPS诱导RAW264.7细胞中表现出一氧化氮(Nitric Oxide, NO)生成的抑制作用(IC50值分别为11.3和19.1 μM)。其中,化合物22的抗炎活性为首次报道。此外,乌苏烷型三萜类化合物2α,20β-二羟基-乌苏酸(isoyarumic acid,9)对人乳腺癌细胞MDA-MB-231表现出一定程度的细胞毒作用(IC50值为17.6 μM)。

A phytochemical investigation of the 90% MeOH extract of the leaves of Turpinia arguta led to the identification of 22 structurally diverse terpenoids, including two new ones: argutacid A (1, a 15-oxo-17-norabietane-type diterpenoid) and argutacid B (2, a labdane-type diterpenoid). Their structures were determined using spectroscopic techniques including mass spectrometry, one-dimensional/two-dimensional nuclear magnetic resonance (NMR) spectra, and electronic circular dichroism (ECD). Compounds 4, 7, 8, 10-14, 16-20, and 22 are reported from T. arguta for the first time. The isolated compounds were evaluated for their anti-inflammatory activity in lipopolysaccharide (LPS)-induced RAW 264.7 cells by suppressing nitric oxide (NO) production. Two oleanolic acid derivatives, pomolic acid (19) and 3β-cis-p-coumaroyloxy-2α,23-dihydroxyolean acid (22), were found to have anti-inflammatory activities with IC50 values of 11.3 and 19.1 μM, respectively. Such an anti-inflammatory effect of 22 was reported for the first time. Furthermore, isoyarumic acid (9, a ursolic acid derivative) exhibited moderate cytotoxic effect against MDA-MB-231 cells, with an IC50 value of 17.6 μM.
