TL;DR: Plants in which growth was reduced by low and high Al applications were designated as Al-sensitive plant and Al-medium tolerant plants and plants tolerant to or stimulated by Al were classification based on the criteria of Al accumulation.
Abstract: Plants in which growth was reduced by low and high Al applications were designated as Al-sensitive plant (Hordeum vulgare) and Al-medium tolerant plants (Leucaena leucocephala, Ischaemum barbatum, Stylosanthes guianensis, and Fagopyrum esculentum), respectively, while plants in which growth was not affected or was stimulated by Al application were designated as Al-tolerant plant (Brachiaria ruziziensis) and Al-stimulated plants (Melastoma malabathricum, Melaleuca cajuputi, Acacia mangium, Hydrangea macrophyila, Vaccinium macrocarpon, Polygonum sachalinense, and Oryza sativa), respectively. Plants tolerant to or stimulated by Al were further classified based on the criteria of Al accumulation: 1) Al-excluders such as M. cajuputi, A. mangium, L. leucocephala, I. barbatum, S. guianensis, and O. sativa, 2) Al root-accumulators such as V. macrocarpon, B. ruziziensis, and P. sachalinense, and 3) Al-accumulators such as M. malabathricum, H. macrophylla, and F. esculentum. The growth and N, P, and K upta...

TL;DR: Activity‐directed fractionation of the PMC indicated that the antioxidant components were contained in the ethylacetate fraction, indicating its ability to protect against CCl4‐induced hepatotoxicity in rats and to scavenge ferri‐heme oxidants generated in an in vitro system.
Abstract: We have demonstrated the presence of both in vivo and in vitro antioxidant activities in the crude waterâextract of the root of Polygonum multiflorum Thunb (PMC), as indicated by its ability to protect against CCl4âinduced hepatotoxicity in rats and to scavenge ferriâheme oxidants generated in an in vitro system Activityâdirected fractionation of the PMC indicated that the antioxidant components were contained in the ethylacetate fraction

TL;DR: In this article, a tonic liquid is prepared with ginseng, polygonum multiflorum, honey and sorghum wine as main material through extraction and refining, which contains various ammino acids and trace elements essential to human body.
Abstract: The said tonic liquid is prepared with ginseng, Polygonum multiflorum, honey and sorghum wine as main material through extraction and refining. It contains various ammino acids and trace elements essential to human body, and owing to the synergy of ginseng and Polygonum multiflorum, the said tonic liquid has the functions of dilating coronary artery and brain vessels, nourishing anoxic heart and saccharide-deficiency cardiac muscle and others.

TL;DR: Ethyl acetate-soluble fractions obtained from both the leaves and rhizomes showed effective growth inhibition against Bacillus brevis, Bacillus cereus, Bac bacteria, Curtobacterium flaccumfaciens, Staphylococcus aureus, Aeromonas hydrophila and Pseudomonas fluorescens.
Abstract: The antimicrobial activities of extracts from the leaves and rhizomes of Sachaline giant knotweed, Polygonum sachalinense, were examined. Of all the fractions separated using various solvents from the methanol extracts, the ethyl acetate fractions obtained from both the leaves and rhizomes had the highest antibacterial activity. Chloroform-separated fractions obtained from the rhizomes also displayed high antibacterial activity against some bacterial strains. Ethyl acetate-soluble fractions obtained from both the leaves and rhizomes showed effective growth inhibition against Bacillus brevis, Bacillus cereus, Bacillus coagulans, Curtobacterium flaccumfaciens, Staphylococcus aureus, Aeromonas hydrophila and Pseudomonas fluorescens.
