Ginseng-Polygonum multiflorum tonic liquid and its prepn

Abstract: The said tonic liquid is prepared with ginseng, Polygonum multiflorum, honey and sorghum wine as main material through extraction and refining. It contains various ammino acids and trace elements essential to human body, and owing to the synergy of ginseng and Polygonum multiflorum, the said tonic liquid has the functions of dilating coronary artery and brain vessels, nourishing anoxic heart and saccharide-deficiency cardiac muscle and others.

Study on the Correlationship between the Content of Combined Anthraquinone and Purgative Action of Steamed Polygonum Multiflorum Thunb.

Abstract: Objective To find out the relationship between purgative principles and purgative action after Polygonum multiflorum Thunb.was steamed through high-temperature,so to provide a basis for making quality standards.Methods To determine the content of combined anthraquinone of two specifications(pieces 0.8～1 cm,thick slice 2～4 mm) in steaming by UV spectrophotographic method and to observe purgative actions of two specifications in rats.Results It was the best to steam 6 hours for piece and 4 hours for thick slice without purgative action and the content of combinated anthraquinone was 2.09 mg/g and 2.00 mg/g respectively.Conclusion There is no purgative action after Polygonum multiflorum Thunb.was steamed,the content of combined anthraquinone are significantly lower,so it can be considered combined-anthraquinone as the limited indication of processed Polygonum multiflorum Thunb..

Study on lignans of Polygonum capitatum

Abstract: OBJECTIVE To study the lignan of Polygonum capitatum. METHODS The compounds were isolated and purified by using of SiO2, Sephadex LH-20 column chromatography and pre-HPLC. The structures of the compounds were determined on the basis of their physical properties and the spectral data. RESULTS Four compounds were isolated and identified as schizandriside (1), (-)-isolariciresinol-2a-O-beta-D-xylopyranoside (2), (-) -5 '-methoxyisolariciresinol-2a-O-beta-D-xylopyranoside (3) and nudiposide (4). CONCLUSION Compounds 1 - 4 are isolated from the genus for the first time.
