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. (12Z)-半日花-8(17),12,14-三烯-18-醛(4)、齐墩果酸(7)、阿儒诺酸(8)、2α,3β-二羟基齐墩 果-12-烯-28-酸(10)~白桦脂酸(14)、熊果酸(16)~野鸦椿酸J (20)和3β-顺式-对香豆酰氧基-2α,23-二羟基-齐墩果酸(22)均系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, 对分离得到的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22在LPS诱导RAW264.7细胞中表现出一氧化氮(NO)生成的抑制作用(IC50值分别为11.3和19.1 μmol/L). 此外, 乌苏烷型三萜类化合物2α,20β-二羟基-乌苏酸(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 μmol/L).

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). (12Z)-Labd-8(17), 12,14-triene-18-al (4), oleanolic acid (7), arjunolic acid (8), maslinic acid (10)~betulinic acid (14), ursolic acid (16)~euscaphic acid J (20), and 3β-cis-p-coumaroyloxy-2α,23-dihydroxyolean acid (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 22, were found to have anti-inflammatory activities with IC50 values of 11.3 and 19.1 μmol/L, 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 μmol/L.
