[Chemical Constituents from Eucommia ulmoides].
To investigate the chemical constituents from the barks of Eucommia ulmoides.. After the reflux extraction of the barks of Eucommia ulmoides with 95% ethanol, and the ethyl acetate part was separated and purified by chromatographic methods, such as silica gel, Sephadex LH-20, and ODS C18. The structures of isolated compounds were elucidated with modern spectral methods.. Five lignanoids and three phenylpropanoids were isolated from Eucommia ulmoieds, which were confirmed as cycloolivil (1), (7R, 8S, 8'R)-4, 9, 4', 8'-tetrahydroxy-3, 3'-dimethyoxyl-7, 9'-monoepoxy lignan (2), erythro-guaiacyl-glycerol-β-coniferyl aldehyde ether (3), pinonesinol (4), 8-hydroxypinoresinol (5), C-veratroylglycol (6), β-hydroxyl-3-methoxyl-4-hydroxyacetophenone (7) and 3-hydroxy-4-methoxycinnamaladehyde (8).. Compounds 5–8 are isolated from this plant for the first time. Topics: Drugs, Chinese Herbal; Eucommiaceae; Lignans; Phenols | 2016 |
[Studies on the chemical constituents of Epimedium brevicornum].
To study the chemical constituents of Epimedium breviconum.. Compounds were purificated with various chromatographic techniques such as silica vacuum liquid chromatography and Sephadex LH-20 column chromatography. Their structures were elucidated by physico-chemical methods and spectral analysis.. Ten compounds were obtained and indentified as (7R, 8S) 4,9-dihydroxyl-3,3'-dimethyoxyl-7, 8-dihydrobenzofunan-1'-propanolneolignan-9'-O-alpha-L-rhamnopyranoside (1), (7R, 8S, 8' R) 4, 4', 8', 9-tetrahydroxyl-3, 3'-dimethyoxyl-7, 9'-monoepoxylignan (2), (+)-cycloolivil (3), (3, 5, 7, 4')-tetrahydroxyl-8-isopentene group flavonoids-3-O-alpha-L-rhamnopyranoside (4), beta-sitosterol (5), p-hydroxybenzaldehyde (6), succinic acid (7) and p-hydroxyphenethyl (8).. Compound 1 is isolated from this genus for the first time. Compounds 2,3,5 -8 are isolated from the plant for the first time.
