By using a variety of chromatographic techniques and spectroscopic methods, six compounds were isolated and identified as follows: clemaphenol A (1), aurantiamide acetate (2), camelliagenin A (3), japonica acid (4), labd-13(E)-ene-8α,15-diol (5), and 313-acetoxy-20-oxo-21-nordammaran-23-oic acid (6). Among these products, compounds 1 and 3-6 were obtained from the genus Artemisia for the first time and compound 2 was firstly reported from the species. Additionally, compound 5 displayed an inhibitory effect against the lipopolysaccharide (LPS)-induced nitric oxide (NO) production in BV-2 microglial cells with an IC50 value of 6.68 μM.展开更多
