TL;DR: The structures of these phenylpropanoid glycosides were determined on the basis of their NMR and mass spectroscopic data and are new members of this class.
Abstract: Five diferuloyl esters of sucrose, 6‘-acetyl-3,6-diferuloylsucrose (helonioside B) (1); 2‘,4‘,6‘-triacetyl-3,6-diferuloylsucrose (2); 1,2‘,4‘,6‘-tetraacetyl-3,6-diferuloylsucrose (3); 1,2‘,6‘-triac...

TL;DR: The methanol extract of the whole plant parts of Polygonum viscosum has yielded a flavonol glycoside, 3-O-(6′′-caffeoyl)-β- d -galactopyranoside, the structure of which has been determined unambiguously by UV and a series of one- and two-dimensional NMR experiments.

TL;DR: This review encompasses the natural products literature of some of the different species of plants in the Polygonum species, commonly used in Chinese and Japanese folk medicine for the treatment of bronchial and pulmonary disorders, suppurative dermatitis, gonorrhea, and hyperlipemia.
Abstract: This review encompasses the natural products literature (with the exception of the patent literature or conference abstracts) of some of the different species of plants in the Polygonum species Some of the plants in this genus originated in Japan and were later introduced to other parts of the world These plants are commonly used in Chinese and Japanese folk medicine for the treatment of bronchial and pulmonary disorders, suppurative dermatitis, gonorrhea, and hyperlipemia The main focus will be on plant species from the genus Polygonum which is also synonymous with the genuses, Fallopia and Reytonouria A comprehensive analysis detailing the research on the chemistry of the different classes of natural products from extracts of Polygonum plant species and their modes of action will be reported and the structure-activity relationships will be addressed wherever possible In addition, the evaluations of bioactive compounds of Polygonum species will be discussed in terms of potential biological uses

TL;DR: In this paper, from the whole plant of Polygonum Rumex Patientia L, six anthraquinones compounds were isolated and identified and they are emodin(Ⅰ), chrysophanol (Ⅱ),physcion(⎉),emodin dimethylether (⎁),emodein 8 O β D glucoside(Ω), and xanthorin 5 methylether(↦), the compounds are isolated from this whole plant for the first time

TL;DR: The ultrastructure showed that apoptotic thymocytes density and degree of morphologic change were sequentially in group AMPM AM PM C, and the combination of Astragalus mongholicus and Polygonum multiflorum could give rise to the highest effect.
Abstract: The effect of Astragalus mongholicus, Polygonum multiflorum and the combination of Astragalus mongholicus and Polygonum multiflorum on thymocytes apoptosis induced by cyclophosphamide (Cy) was studied The results were as follows: in the group C (the mice were treated with Cy, Cy mice, the control), their thymocytes revealed obvious apoptosis change, as compared with group C, in group AM, PM and AMPM (the Cy mice were treated for 14 days with Astragalus mongholicus , Polygonum multiflorum and the combination of Astragalus mongholicus and Polygonum multiflorum respectively),using flow cytometry,the sup G1 peaks, labelled ‘Ap’—the hallmark of apoptotic cells appeared, the height of Ap peaks was sequentially in group AMPM AM PM C , and Ap peak did not appear in group O The ultrastructure showed that apoptotic thymocytes density and degree of morphologic change were sequentially in group AMPM AM PM C The results suggested that Astragalus mongholicus and Polygonum multiflorum could play an antagonistic role on thymocytes apoptosis induced by cyclophosphamide, and the combination of Astragalus mongholicus and Polygonum multiflorum could give rise to the highest effect

TL;DR: In this paper, the effect of the tuber of multiflower knotweed (Polygonum multiflorum Thunb,PmT) on the lifespan of Drosophila melanogaster is studied.
Abstract: WT5BZ]The effect of the tuber of multiflower knotweed ( Polygonum multiflorum Thunb ,PmT) on the lifespan of Drosophila melanogaster is studied It shows that extract of PmT can lengthen the average lifespan of Drosophila melangaster obviously, and decrease the lipofuscin and LPO content of salivary gland cell It further accounts the mechanism of anti decrepitude
