Two new butenolides, balanolides A (1) and B (1), were isolated from the aerial parts of the parasitic plant Balanophora fungosa. Their structures were established by comprehensive spectroscopic analysis and quantum chemical ECD calculation. The new butenolides were evaluated for their inhibitory effects against nitric oxide (NO) production in LPS-induced RAW 264.7 macrophage cells. Compounds 1 and 2 displayed moderate anti-inflammatory activity with IC50values of 11.8 and 12.9 μM, respectively.
