Abstract:
Objective: To investigate the chemical constituents from the dried roots and rhizomes of Physochlaina infundibularis. Methods: Repeated chromatography with silica gel, macroporous resin, MCI, and Sephadex LH-20 columns was used to isolate the chemical constituents and their structures were elucidated based on physicochemical properties and spectral data. Results: Seventeen compounds were isolated and identified as hyoscyamine (1), scopolamine (2), anisodamine (3), scopoletin (4), scopolin (5), umbelliferone (6), 6, 7-dimethoxycoumarin (7), 3-methoxyquercetin (8), isoquercitin (9), kaempferol-7-O-β-D-glucoside (10), syringarenol (11), protocatechuic acid (12), methyl 4-hydroxybenzoate (13), 2-hydroxybenzoic acid (14), tropic acid (15), 4- hydroxybenzoic acid (16), and palmitic acid (17). Conclusion: Compounds 7-17 are firstly obtained from the plants in Physochlaina G. Don, and compound 5 is firstly obtained from P. infundibularis.
