Abstract:
Objective: To investigate the chemical constituents in the whole herbs of Pothos chinensis. Methods: The chemical constituents were isolated and purified by various column chromatographic methods and preparative HPLC. Their structures were identified by physicochemical properties and spectral analyses. Results: Seventeen compounds were isolated from the methanol extract and identified as N-trans-cinnamoyltyramine (1), N-trans-p-coumaroyltyramine (2), N-cis-p-coumaroyltyramine (3), N-trans- feruloyltyramine (4), N-cis-feruloyltyramine (5), loliolide (6), dehydrovomifoliol (7), (3S, 5R, 8R, 9R)-5, 8-epoxy-6-megastigmene-3, 9-diol (8), (3R, 6R, 7E)-3-hydroxy-4, 7-megastigmadien-9-one (9), (3R)-4-[(2R, 4S)-2-hydroxy-2, 6, 6-trimethylcyclohexylidene]-3- buten-2-oneiol (10), 7-methoxycoumarine (11), imperatorin (12), 7-hydroxy-8-methoxycoumarin (13), 6-hydroxy-7-methoxycoumarin (14), indole-3-aldehyde (15), (-)-medioresinol (16), and daidzein (17). Conclusion: All the compounds are isolated from the plants in Pothos L. for the first time.
