Objective To further investigate the chemical constituents of the ethanol extract from the aerial parts of Clematis manshurica. Methods The compounds were isolated and purified by column chromatography of silica gel, ODS, and semi-preparative HPLC. Their structures were elucidated by spectral analyses, including MS, 1D and 2D NMR spectral techniques. Results Eighteen compounds were isolated from the ethanol extract of the aerial parts of C. manshurica, and were identified as β-amyrin acetate (1), (5S)-dihydro-5-hydroxymethyl-2(3H)-furanone (2), 5-(hydroxymethyl)-2-furancarboxaldehyde (3), syringaldehyde (4), isololiolide (5), loliolide (6), (−)-syringaresinol (7), clematichinenol (8), grasshopper ketone (9), syringic acid (10), ferulic acid (11), (5R)-dihydro-5-hydroxymethyl-2(3H)-furanone (12), 3,4-dihydroxyacetophenone (13), 3,4-dihydroxy- benzaldehyde (14), 1,3-trans-tetraoxy-1-methyl-3-phenylindan (15), trans-dihydro-4-hydroxy-5-hydroxymethyl-2(3H)-furanone (16), (5S)-5-hydroxymethyl-2(5H)-furanone (17), and japonicin A (18). Conclusion Compounds 4-6, 9, 13-15, and 18 are firstly isolated from genus Clematis, and compounds 1-2 and 7-8 are obtained from this plant for the first time.
