TL;DR: In this paper, the authors disclosed a polygonum capitatum planting method, which comprises the following steps: disinfecting seeds of polygonal capitatum to remove quilts, preparing a base fertilizer from polygonalm capitatum waste residues, sawdust, fine soil, a zinc fertilizer and humic acid substances; laying the base fertilizer on a seedbed in a plastic greenhouse, and watering after laying is completed; from February to March, evenly mixing the processed polygonm capitatum seeds with the fine soil and then evenly scattering the mixture on the seedbed; from March
Abstract: The invention discloses a polygonum capitatum planting method. The method comprises the following steps: disinfecting seeds of polygonum capitatum to remove quilts; preparing a base fertilizer from polygonum capitatum waste residues, sawdust, fine soil, a zinc fertilizer and humic acid substances; laying the base fertilizer on a seedbed in a plastic greenhouse, and watering after laying is completed; from February to March, evenly mixing the processed polygonum capitatum seeds with the fine soil, and then evenly scattering the mixture on the seedbed; from March to April, opening a film of thegreenhouse, removing weeds, and watering; before transplanting, laying the base fertilizer in a field, then finely crushing the surface soil, and evenly mixing the compound fertilizer with the surfacesoil and then laying on the outermost layer of the field; after field preparation is completed, transplanting to the field; 10-20 days after transplanting, removing the weeds, applying the fertilize,and then carrying out conventional weeding and deinsectization every month; and harvesting in sunny days from August to November, drying in the sun and warehousing. The method disclosed by the invention has the characteristics of low medicine residue treatment and polygonum capitatum planting cost, good polygonum capitatum growth, high yield and good quality.

TL;DR: In this article, the results of the investigations in the fi eld of standardization of plant material of Polygonum hydropiper L. herbs were discussed. And the methods of qualitative analysis of polygons herbs with using of thin layer chromatography and spectrophotometry were developed.
Abstract: In the present paper are discussed the results of the investigations in the fi eld of standardization of plant material of Polygonum hydropiper L. There were isolated from the investigated plant the predominant fl avonoids pinostrobin and also a new natural compound – 21,61-dihydroxy-41,51-dimethoxychalcone (polygochalcone), which have the diagnostic signifi cance. There was developed the methods of qualitative analysis of Polygonum hydropiper L. herbs with using of thin layer chromatography (determination of pinostrobin) and spectrophotometry (the maximum of absorption at 283 ± 3 nm and «shoulder» at 340–360 nm). There was developed the method of quantitative determination of total fl avonoids Polygonum hydropiper L. herbs using differential spectrophotometry with analytical wavelength at 394 nm. There was established that the content of total fl avonoids in the Polygonum hydropiper L. herbs varies from 2,47 to 4,45 % (calculated on pinostrobin). The relative degree of the determination of the total fl avonoids in the Polygonum persicaria L. herbs in developed method with confi dence probability 0,95 is no more than + 4,15 %.
