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.
Objective: To investigate the chemical components of the whole herb of Tripterospermum chinense.
Methods: Various column chromatography methods were used in the isolation and purification. Physio-chemical constant determination and spectral analysis were adopted to determine the chemical structures.
Objective: To investigate the chemical constituents of Eucommia ulmoides leaves.
Methods: Various column chromatography were used in the isolation and purification, physiochemical constant determination and spectral analysis were adopted to determine the chemical structures.
Results: Ten compounds were isolated and identified as borreriagenin (1), n-butyl-O-β-D-fructopyranoside (2), α-D-glucopyranosyl-(1-->1')-3'-amino-3'-deoxy-β-D-glucopyranoside (3), β-D-fructofuranosyl-α-D-galactopyranoside (4), β-D-fructose (5), diisobutyl phthalate (6), 5-hydroxy-9-isopropylether-guaiacylglycerol (7), 4-hydroxyphenylethanol-8-O-β-D-apiofuranosyl(1-->6)-β-D-glucopyranoside (8), lariciresinol (9), and (3S,5R,6R,9S)-tetrahydroxy-7-ene-megastigmane (10).
Objective: To investigate the chemical constituents of Gardenia jasminoides fruits.
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: Twelve compounds were isolated from Gardenia jasminoides including jasminoside I (1), gardenoside (2), gardaloside (3), 3-hydroxy-urs-12-ene-11-ketone(4), 5, 4'-dihydroxyl-7, 3', 5'-trimethoxyflavone (5), 5, 7, 3', 4', 5'-pentamethoxyflavone(6), 3, 5, 6, 4'-tetrahydroxy-3', 5'-dimethoxyflavone (7), shikimic acid (8), 1, 2, 4-benzenetriol (9), 3, 4-dimethoxy-benzoic acid (10), dibutyl phthalate (11) and diisobutyl phthalate (12).
Objective: To investigate the chemical constituents in the roots and rhizome of Trillium tschonoskii.
Methods: The roots and rhizome of Trillium tschonoskii were extracted with 70% ethanol and purified by polyamide, silica gel, RP-C18 and Sephadex LH-20 column chromatography. Chemical structures were identified by MS, 1D and 2D NMR experiments.
