Article Synopsis
- The study aimed to investigate the phenylpropanoids found in the plant Gardenia jasminoides.
- Various chromatography methods were used for isolation, purification, and determining the chemical structures of the compounds.
- Eight unique compounds were isolated from the plant, marking the first time these specific compounds have been documented from Gardenia jasminoides.
Objective: To investigate the chemical constituents of active components of Saururus chinensis on anti-nicotine withdrawal symptoms.
Methods: Various column chromatography were used in the isolation and purification, and physiochemical constant determination and spectral analysis were adopted to determine the chemical structures.
Results: Six chemical compounds were isolated from the active part of anti-withdrawal symptoms, and were identified as 4'-hydroxyl-3,3',4,5,5'-pentamethoxy-7,7'-epoxylignan (1) ,3-(2-nitroethyl)-1-methoxyindole(2), elemicin (3), erythro-(7R, 8S) - (-) - (3,4,5-trimethoxy-7-hydroxy-1'-allyl-3', 5'-dimethoxy)-8-O-4'-neolignan (4), 3,4,5-trimethoxy-phenylacrylaldehyde (5) and dibutyl phthalate (6).
Objective: To investigate the chemical constituents from the roots and rhizome of Trillium tschonoskii.
Methods: The85% methanol elution parts from the roots and rhizome of Trillium tschonoskii were separated and purified by polyamide,silica gel,RPC18,Sephadex LH-20 column chromatography and the preparation of high performance liquid. Chemical structures were identified by MS,1D and 2D-NMR experiment.
