TL;DR: The quantitative analysis of multicomponents by the single-marker (QAMS) method was established and the relationship between F value and the steaming time was found to identify and differentiate Polygoni multiflori Radix Preaparata and its processed product.
Abstract: The quantitative analysis of multicomponents by the single-marker (QAMS) method was established and the relationship between F value (the ratio of the sum of the contents of emodin-8-O-β-D-glucopyranoside and physcion-8-O-β-D-glucopyranoside to the sum of the contents of emodin and physcion) and the steaming time was found to identify and differentiate Polygonum multiflorum Radix and its processed product. Emodin was considered as the control substance, and the correction factors of physcion, emodin-8-O-β-D-glucopyranoside, and physcion-8-O-β-D-glucopyranoside were computed. In addition, the contents of the four components were determined. When the F value is greater than or equal to 1.0, the sample was identified as Polygonum multiflorum Radix, and if the F value was between 0.6 and 1.0, the sample of Polygoni multiflori Radix Preaparata was processed incompletely. The F value of the qualified Radix Polygonum multiflorum should be no more than 0.6. However, the influence of different sample injection volumes and the chromatographic columns and instruments used on the durability of the correction factors and RSD ≤3% hindered accurate identification; therefore, a QAMS method using an external standard value with methodological verification was developed. We redefined the “Polygonum multiflorum rules.” The method using “Polygonum multiflorum rules” revised after optimization of the determination results was used, as it was accurate and led to convenient operation and low inspection costs, and moreover, the method could differentiate Polygoni multiflori Radix Preaparata and Polygonum multiflorum Radix medicinal samples and precisely identify samples that were different from the completely processed product Polygoni multiflori Radix Preaparata.

TL;DR: Of the three weed species, Polygonum lapathifolium appeared to be the most, and P. aviculare the least, competitive towards kale, while P. persicaria was slightly less competitive than P. lapath ifolium, and the two latter species were much higher in dry-matter production than the former.
Abstract: Summary. The results of a pot experiment on the mutual interference between kale and three weed species are reported. The puts were sunk in soil and surrounded by kale plants so as to provide illumination conditions similar to those likely to be found in a field crop of kale. Of the three weed species, Polygonum lapathifolium appeared to be the most, and P. aviculare the least, competitive towards kale. P. persicaria was slightly less competitive than P. lapathifolium. The two latter species were much higher in dry-matter production than P. aviculare and showed greater responses to changes in the number of kale or weed plants per pot.

Abstract: The invention provides a Chinese herb additive. The Chinese herb additive is applied to livestock breeding and prepared from isatis roots, wikstroemia indica, ginseng, garlic, calamus faberii, homalomena occulta, bulbus fritillariae cirrhosae, rhizoma smilacis glabrae, rhizoma zingiberis, calculus bovis, white paeony roots, white atractylodes rhizome, corn stigma, paederia scandens, cockscomb flowers, radix ophiopogonis, eucommia ulmoides, kudzuvine roots, mint, kalimeris indica, nux vomica, pseudo-ginseng, hawthorn fruits, schisandra chinensis, gastrodia elata, asparagus cochinchinensis, plantain herbs, sculellaria barbata, pomegranates, folium artemisiae argyi, lilies, artemisia apiacea, platycladus orientalis, polygonum cuspidatum, houttuynia cordata, eritrichium pedumculare, chrysopogon aciculatus, dayflower herbs, pollen pini, dogwood, rheum officinale, subprostrate sophora, glossy privet fruits, cimicifugae foetidae, elecampane, pubescent holly roots, horsetail, earthworms, safflower carthamus, wild pepper, polygonum multiflorum, honeysuckles, herba andrographitis, herba epimedii, sealwort, areca nuts, radix stemonae and hydnocarpus anthelmintica. When applied to livestock breeding, the Chinese herb additive can balance various nutrients needed by livestock and reduce the disease incidence of livestock in growth; besides, the Chinese herb additive has no side effect.
