Culture soil of polygonum multiflorum and preparation method thereof

Abstract: The invention relates to the technical field of planting of polygonum multiflorum, in particular to culture soil of polygonum multiflorum and a preparation method thereof. The culture soil is mainly prepared from the following raw materials of 30% to 40% of furnace residues, 20% to 30% of leaf mold, 10% to 20% of corn straw powder, 5% to 15% of vegetable seed meal, 3% to 8% of composted cow dung,1% to 3% of chitosan, 1% to 5% of bone meal, 1.5% to 2.5% of ammonia sulfate, and 0.5% to 1.5% of monopotassium phosphate. The culture soil has the advantages that after the raw materials are preparedaccording to the ratio, the air ventilating and water permeation properties are good, the mildew-proof and anti-corrosive effects are obvious, the planting survival rate of polygonum multiflorum is increased, the planting cost of planting farmers is reduced, and the economic benefit is increased.

Abstract: The invention discloses a cultivation technology for polygonum multiflorum. The cultivation technology for the polygonum multiflorum comprises the following steps of land preparation, fertilizer application, sowing, seed reserving and collecting, seedling management and harvesting and other cultivation technologies. Polygonum multiflorum cultivation is simple and convenient, cost is low, the profit is high, and the technology can be widely developed and used.

Polygonum Multiflorum-induced Hepatic Lesion:Retrospective Analysis and Clinical Monitoring

Abstract: OBJECTIVE:To review the hepatic lesions cases induced by Polygonum multiflorum and to probe into the approach to the clinical monitoring on which.METHODS:The hepatic lesions cases induced by Polygonum multiflorum and the causes were analyzed.RESULTS:Polygonum multiflorum-induced hepatic lesion was caused by the toxic ingredients contained,the deficiency of liver enzymes,genetic genes or poor recognition on its side effects.CONCLUSION:Monitoring on liver function before and after administration of Polygonum multiflorum attenuates its damage on livers.

Inactivating agents for hbs anitgen

CONSTITUTION:An inactivaing agent comprsing lignin extracted from (A) gymnospermous plants, e.g. a podocarp, black pine, longleaf pine, fir, silver fir, sugi, hinoki, or Ephedra sinica stapf, or (B) choripetalous plants, e.g. a weeping willow, Alnum firma Sieb.et Zucc., Quercus glauca Thunb., Polygonum multiflorum Thunb., rhubarb, cinnamon tree, laurel tree, Eurya japonica Prunus yedoensis Matsum., strawberry, sugar maple, Acer Buergeriana Miq., winged spindle tree, loosestrife, or Cornus officinalis Sieb. et Zucc. as an active constituent.

[Biotransformation of 4-methyl-7-allyloxy coumarin by transgenic hairy roots of Polygonum multiflorum].

Abstract: Objective To synthesis 4-methyl-7-allyloxy coumarin by Williamson etherification from 4-methyl-7-hydroxy coumarin and apply as a substrate in hairy roots of Polygonum multiflorum. Methods The synthesis reaction of 4-methyl-7-allyloxy coumarin used the allyl bromide and potassium carbonate as catalysts, and acetone as solvent reacted for 17 hours, then the product was isolated. 4-methyl-7-allyloxy coumarin was added into the media of supension transgenic hairy roots of Polygonum multiflorum which had been precultured for 8 d, and then co-cultured for another 7 d. The biotransformation products were detected by TLC and HPLC and isolated by various chromatographic methods. Results Two biotransformation products, 4-methyl-7-hydroxy coumarin and 4-methyl-coumarin-7-O-beta-D-glucoside were isolated and identified. Conclusion Hairy roots of Polygonum multiflorum contains not only glycosyltransferase but also hydrolysis enzymes.
