Three New Phenylpropanoids from Inula nervosa Wall .

Three new phenylpropanoid compounds, named nervolans A–C (1–3, resp.), together with two other known phenylpropanoids, coniferyl diangelate and sinapyl diangelate, were isolated from the aerial parts of Inula nervosa Wall. (Asteraceae), a traditional Chinese medicinal plant. The structures of 1–3 were elucidated by detailed spectroscopic analyses, including HR‐ESI‐MS data and 2D‐NMR spectroscopy. Compounds 1–5 exhibited mild inhibitory effects against NO production in LPS‐stimulated RAW264.7 cells.
