Five new aromatic compounds, designed as lucidumins A-D (1-4) and lucidimine E (9), along with seven known aromatic compounds (5-8, 10-12) were isolated from Ganoderma lucidum. Their structures were determined by spectroscopic method. Bioactive evaluation showed that compounds 2-4 and 6-10 displayed remarkable neuroprotective activities against corticosterone-induced PC12 cell damage, with the cell viability ranging from 69.99% to 126.00%; and compounds 1-4, 9 and 10 exhibited significant anti-inflammatory activities against LPS-induced nitric oxide (NO) production in RAW264.7 macrophages, with ICvalues ranging from 4.68 to 15.49 μM. In particular, compound 10 showed remarkable neuroprotection with ECvalue of 2.49 ± 0.12 μM, and potent anti-inflammation with ICvalue of 4.68 ± 0.09 μM.
