Abstract:
Salsola collina is widely distributed in droughty and semi-droughty area, which is used as a kind of folk remedy in traditional Chinese medicine for treatment of hypertension. The study is on the chemical constituents of this herb from its aerial parts to obtain its active constituents. Dried and crushed aerial parts of this herb were extracted three times with 95% EtOH at reflux. The ethanol extracts were combined and concentrated under reduced pressure at 70 degrees C to yield residue, which was suspended in water and successively partitioned with light petroleum, chloroform and n-butanol. The chloroform and n-butanol fractions were treated by various chromatographic techniques, such as silica gel, C18 reversed-phase silica gel and macroporous resin column chromatography. Compounds were elucidated by their physicochemical properties and spectroscopic analysis. In the course of our study on searching biological active components from this herb, a new alkaloid together with three known alkaloids were isolated and identified as N-transferuloyl-3-methyldopamine (1), 3-[4-(beta-D-glucopyranosyloxy)-3-methoxyphenyl]-N-[2-(4-hydroxyl-3-methoxyphenyl) ethyl]-2-propenamide (2), salsoline A (3), salsoline B (4). Compound 4 is a new compound and named as salsoline B, while compound 2 was obtained in Salsola collina for the first time.
