TL;DR: The results indicate: the content of stilbene glucoside in the root tuber is the highest, then the old root and old stem, but it is very low in the young parts of vegetative organs and generative organ.
Abstract: In this paper,content changes of stilbene glucoside in Polygonum multiflorum Thunbare investigatedThe results indicate:the content of stilbene glucoside in the root tuber is the highest,then the old root and old stem,but it is very low in the young parts of vegetative organs and generative organIt is gradually increased in the root tuber and old stem with adding of growth yearsIt increased from June to October,reached the highest value in October,then drops graduallyIt is the highest in parts of the root tuber,the lowest in the parenchymaCongsidering content changes of stilbene glucoside,a rational gather time is in October,and old root and old stem should make full use

TL;DR: The polygonum multiflorum culture soil comprises the following components in parts by weight: 10 to 20 parts of coal ash, 5 to 10 parts of coarse sand, 20 to 25 parts of humic acid, animal excrement, 8 to 10 part of straw powder, 50 to 60 parts of black soil, 10 to 15 parts of active sludge, 5 TOE powder and 3 to 5 parts of plant ash as discussed by the authors.
Abstract: The invention relates to the field of cutting seedling of polygonum multiflorum, and particularly relates to to polygonum multiflorum culture soil. The polygonum multiflorum culture soil comprises the following components in parts by weight: 10 to 20 parts of coal ash, 5 to 10 parts of coarse sand, 20 to 25 parts of humic acid, 10 to 20 parts of animal excrement, 8 to 10 parts of straw powder, 50 to 60 parts of black soil, 10 to 15 parts of active sludge, 5 to 10 parts of eggshell powder and 3 to 5 parts of plant ash. The culture soil is fertile, good in breathability, excellent in water drainage, rich in humic acid, favorable for the growth of the cutting seedling of the polygonum multiflorum, low in production cost and also capable of increasing the cutting seedling success rate of the polygonum multiflorum.

TL;DR: In this article, the antiplasmodial activity of polygonum leaves was evaluated using the DPH test and aqueous ethanolic extracts of Benin's Polygonum senegalense leaves.
Abstract: Drug resistance developed by Plasmodium falciparum doubled their rates of infection in the last two decades and encourages efforts to further explore natural materials that can be used as a new antimalarial drug. Thus, present study aims to evaluate "in vitro" antioxidant (DPPH test) and antiplasmodial activities of ethanolic and aqueous ethanolic extracts (30/70) of Benin’s Polygonum senegalense leaves. Compared with the ethanolic extract, only the hydroethanolic extract has a good anti-radical activity with an IC50 (0.18 mg/mL) similar to that of quercetin (0.1 mg/mL) which is one of references antioxidants used in this study. This activity would be due to the presence of phenolic compounds identified during the phytochemical screening of Polygonum leaves and their high presence in the aqueous ethanolic extract (81.76 mg/g against 17.83 mg/g for the ethanol extract) revealed by quantitative analysis. Both extracts investigated showed good antiplasmodial activity (IC50 50 μg/mL). The plant material studied is therefore a potential source of phenolic compounds, antimalarial and anti-radical molecules. Keywords: Polygonum senegalense, Phenolic compounds, Antiradical, Antiplasmodial.

TL;DR: The results showed the essential oil gargle of Kesum leaves (Polygonum Minus Huds) at concentrations of 0.025% and 0.05% were not able to inhibit the growth of the two bacteria, which means increasing the amount of concentration or making mouthwash in other forms is expected to increase its antibacterial effect.
Abstract: Polygonum Minus Huds methanol extract from several previous studies has antibacterial properties in bacteria in the mouth such as Streptococcus Mutans, Staphylococcus Aureus, Salmonella Typhi, Escherichia Coli, etc. The cause of gingivitis is Streptococcus Sanguinis and anaerobic bacteria in the subgingival, which is porphyromonas gingivalis. Polygonum Minus Huds has the potential to be an antibacterial mouthwash for bacteria that causes caries and gingivitis. This research aims to make a mouthwash based on the essential oil of Polygonum Minus Huds and determine its antibacterial properties in mouthwashes of 0.025% and 0.05% concentrations to find antibacterial activity on Streptococcus Mutans and Sanguinis. The research was conducted in June 2019 at the Chemistry Laboratory of Faculty of Mathematics and Natural Sciences, the University of Tanjungpura in Pontianak Lab and Health Polytechnique Pontianak Integrated Lab. Design Quasi-experimental research used post-test only control group design, mouthwash formulation with essential oil concentrations of 0.025% and 0.05%, positive control using non-alcoholic mouthwash, and negative control (Aquades). Statistical analysis was performed univariately. The results showed that the best mouthwash was 2.5 ml of Tween 80 and 2.5 ml of glycerin. The results showed the essential oil gargle of Kesum leaves (Polygonum Minus Huds) at concentrations of 0.05%, and 0.02%, which is the bacteria of Streptococcus Mutans and Streptococcus Sanguinis were not able to inhibit the growth of the two bacteria. Increasing the amount of concentration or making mouthwash in other forms is expected to increase its antibacterial effect.

TL;DR: In this article, the pine needle and polygonum multiflorum tea is used to prolong the life of the pine needles and the polygonal multilayer multiflorium tea.
Abstract: The invention relates to pine needle and polygonum multiflorum tea capable of prolonging life. The tea comprises the following raw materials in parts by weight: 50-60 parts of pine needles, 10-20 parts of polygonum multiflorum, 5-10 parts of folium mori and 20-30 parts of cypress seed shell. A preparation method of the pine needle and polygonum multiflorum longevity tea comprises the following steps: picking the pine needle which grows in the same year, cleaning, de-waxing, deactivating, drying and crushing for later use; b, selecting the polygonum multiflorum which grows for many years, cleaning, slicing, drying and crushing for later use; c, picking the fresh folium mori, cleaning, drying and crushing for later use; d, selecting the deseeded cypress seed shell in the same year, cleaning, drying and crushing for later use; e, accurately weighing the crushed later use pine needle, polygonum multiflorum, folium mori and cypress seed shell prepared in the steps a-d and putting into a stirrer to uniformly stir; f, selecting a nylon yarn as an inner packaging bag, wherein one small bag contains 10 grams, and every 10 small bags form one big bag, and the packaging bag is used for packaging.
