Three new caryophyllane-type sesquiterpenoids, linariophyllenes A-C (1-3), two new hamamelitol derivatives, linaritols A (4) and B (5), two new chromones, linariosides A (6) and B (7), and three known chromones, cnidimol C (8), monnieriside A (9), and undulatoside A (10), were identified from the aerial parts of Evolvulus linarioides. The structures of these compounds were elucidated by NMR, MS, and IR data. The absolute configurations of compounds 1-5 and 7 were established via electronic circular dichroism data. The anti-inflammatory potential of compounds 1-5 and 7-10 was evaluated by determining their ability to inhibit the production of nitric oxide (NO) and proinflammatory cytokine IL-1β by stimulated J774 macrophages. Compounds tested at noncytotoxic concentrations inhibited NO production by macrophages, exhibiting IC50 values between 17.8 and 66.2 μM, and inhibited IL-1β production by stimulated macrophages by 72.7-96.2%.

亚麻volv的地上部分的生物活性化合物。

三种新的石竹兰型倍半萜类化合物,亚麻酸亚麻油AC(1-3),两种新的金缕梅醇衍生物,亚麻苦油醇A(4)和B(5),两种新的色酮,亚麻油苷A(6)和B(7)以及三种已知的色酮,cnidimol C(8),monnieriside A(9)和undulatoside A(10)是从E草的地上部分鉴定出来的。通过NMR,MS和IR数据阐明了这些化合物的结构。化合物1-5和7的绝对构型是通过电子圆二色性数据建立的。通过确定化合物抑制刺激的J774巨噬细胞产生一氧化氮(NO)和促炎细胞因子IL-1β的能力,评估了化合物1-5和7-10的抗炎潜力。在非细胞毒性浓度下测试的化合物可抑制巨噬细胞产生NO,IC50值介于17之间。
