TL;DR: A contemporary summary of biological and pharmacological investigate on Polygonum chinensis belong to family polygonaceae will be presented and critically evaluated.
Abstract: The genus Polygonum (Polygonaceae), comprising about 300 species, is distributed worldwide, mostly in north temperate climates, is interesting from both biological and phytochemical perspectives. In this review, a contemporary summary of biological and pharmacological investigate on Polygonum chinensis belong to family polygonaceae will be presented and critically evaluated. The plant consists of alkaloids, amino acids, carbohydrates and glycosides, fixed oils and fats, flavones and flavanones, gums and mucilage, phenolic compounds and tannins, proteins, saponins, sterols, and triterpenoids. The Significant findings in the treatment of various diseases such as snake-bites, inflammatory, anticancer, antibacterial, antiviral, antiseptic, antifungal, diabetic, hypertension, hyperlipemia, jaundice, hemorrhage, cough, fever, ulcers, skin inffections, anemia, diarrhea and various urologic disorders, have been presented in ethnobotanical reports.

TL;DR: These new loci in Polygonum cespitosum Blume will provide tools for examining genetic relatedness among introduced and native populations of this and other related species.
Abstract: Premise of the study: We isolated and characterized microsatellite markers in Polygonum cespitosum Blume, an herbaceous annual plant species introduced into North America from Asia that has recently become invasive. METHODS: and Results: A total of 12 polymorphic and 3 monomorphic loci were screened in 1-2 individuals from each of 20 populations from the introduced and native range, for a total of 24 samples. The number of alleles per locus in the polymorphic loci ranged from 3 to 9, and expected heterozygosity ranged from 0.156 to 0.838. CONCLUSIONS: These new loci will provide tools for examining genetic relatedness among introduced and native populations of this and other related species.

TL;DR: In this article, a hair growth composition is obtained by including one or more kinds selected from a stilbene-based compound represented by the formula (A and B are each a halogen, amino or the like; n and m are each an integer of 0-5), its polymer and plant extracts containing the same.
Abstract: PROBLEM TO BE SOLVED: To obtain a hair growth composition having prophylactic effects on alopecia and hair growth effects by including a stilbene-based compound abundantly contained in a plant of the family Polygonaceae or Vitaceae or Veratrum album as an essential ingredient. SOLUTION: This hair growth composition is obtained by including one or more kinds selected from a stilbene-based compound represented by the formula (A and B are each a halogen, amino or the like; n and m are each an integer of 0-5), its polymer and plant extracts containing the same. For example, the compound represented by the formula is resveratrol, polydatin or α-viniferin and can be synthesized by the Wittig reaction of the corresponding phosphonium salt with the corresponding aldehyde. A dried material, an extract, etc., prepared by carrying out a treatment such as drying, extraction or purification from a suitable site of a rhizome, a fruit, etc., of the plant containing the compound represented by the formula (e.g. Polygonum multiflorum which is a plant of the family Polygonaceae, Vistis vinifra species of the family Vitaceae or Veratrum album) may be used. The stilbene-based compound is preferably contained in an amount of 0.0001-5 wt.% in the composition.
