TL;DR: It's possible to biotransform furannoligularenone by hairy roots of P. multiflorum and the mole conversion ratio of the substrate reached the highest (27.2%).
Abstract: Objective To investigate the biotransformation of furannoligularenone by hairy roots of Polygonum multiflorum. Methods Furannoligularenone was added to the medium of hairy roots of P. multiflorum after precultured for 9 days, then they were co-cultured. The products were isolated and identified on the basis of their physical chemical properties and spectroscopic data. The T-C curve of biotransformation was investigated with HPLC. Results The hairy roots of P. multiflorum transformed the substrate to two products, 3-oxo-eremophila-1,7(11)-dien-12,8-olide(II) and 3-oxo-8-hydroxy-eremophila-1,7(11)-dien-12,8-olide(III). After co-cultured for 3 days, the mole conversion ratio of the substrate reached the highest (27.2%). Conclusion It's possible to biotransform furannoligularenone by hairy roots of P. multiflorum.

TL;DR: A brief revision of this genus in Iran is presented and the number of species for Polygonum L. sensu lato has been reduced to 25 species.
Abstract: The genus Polygonum L. sensu lato is revised based on articles, herbarium documents and field observations. In this article, a brief revision of this genus in Iran is presented. It was first described by Rechinger and Schiman-Czeika [1] for flora Iranica and has included up to 53 species. The last revision of this genus has been made by Mozaffarian [2], and the genus Polygonum L. sensu lato is divided into 3 genera (Polygonum L. sensu sticto, Bistorta Adans. and Persicaria Mill.). But in present study, according to our field observations and herbarium materials, the genus Polygonum L. sensu lato has to be separated into 5 different genera including Aconogonon (Meisn.) Rchb., Bistorta (L.) Scop., Fallopia Adans., Persicaria (L.) Mill., and Polygonum L. sensu stricto. The number of species for Polygonum L. sensu lato has been reduced to 25 species. For these 5 genera, new identification keys have been created.

TL;DR: In this article, the chemical constituents of the 95% EtOH extract of the rhizoma of Polygonum bistorta L. were identified by column chromatography and identified by physico-chemical characters and spectroscopic analysis.
Abstract: Objective To study the chemical constituents of the 95% EtOH extract of the rhizoma of Polygonum bistorta L.Methods The chemical constituents were isolated by column chromatography and identified by physico-chemical characters and spectroscopic analysis.Result Five compounds were isolated,and identified as gallic acid (Ⅰ),succinic acid (Ⅱ),quercetin (Ⅲ),quercetin-5-O-β-D-glucopyranoside (Ⅳ) and 3,4-dihydroxy benzoic acid (Ⅴ).Conclusion CompoundⅡ,Ⅳ were isolated from Polygonum genus for the first time.
