Provided are a rubber composition for a tire which makes it possible to improve the handling stability and fuel economy in a well-balanced manner by a simple method without requiring any chemical reaction process for surface treatment of microfibrillated plant fibers; and a pneumatic tire formed from the rubber composition. The rubber composition for a tire contains: a rubber component; microfibrillated plant fibers; a phenol resin; and a curing agent. It is preferable that the rubber component should include at least one selected from the group consisting of natural rubber, modified natural rubber, synthetic rubber, and modified synthetic rubber, and it is preferable that the microfibrillated plant fibers should be cellulose microfibrils.

Rubber composition for tire and pneumatic tire

The invention discloses a temperature control greenhouse seedling raising method of polygonum capitatum seeds. According to the method, casing removing is carried out on the seeds before sowing, the seeds are then immersed in clear water, full seeds sinking at the bottom are selected and dried and then mixed with fine sand in the proportion of 1 : 2 and further sown in a seedling raising tray filled with seedling raising matrix evenly, and when 2 main leaves appear the seedlings are transplanted to a seedling raising potted tray, and when 6 main leaves appear the seedlings are transplanted to the land. The temperature in a greenhouse during the seedling raising is limited at 20 + / - 2 DEC G, and the moisture is limited at 50-60%. The temperature control greenhouse seedling raising method of the polygonum capitatum seeds has the advantages of being fast, simple, and saving in cost. Seedling management is easy, and the germination time and the land transplanting time are enabled to be early, and strong seedlings are cultivated.

The invention relates to a novel method for planting polygonum capitatum as a medicinal material of a Relinqing granule. The method specifically comprises the steps of: (1), selecting a cultivated land suitable for the growth of polygonum capitatum; (2), preparing land, namely, deeply ploughing the land for above 30cm before frost comes, and freezing partial pests and harmful microorganisms to death by using low temperature in winter; (3), carrying out lifting of seedlings between the last ten-day period of April to the middle ten-day period of the May; (4), transplanting and planting and filling gaps with seedlings, namely, transplanting in cloudy or rainy days or the afternoons of sunny days between the end of the April and the middle ten-day period of the May, and immediately filling the gaps with the seedlings within one week after transplanting; (5), carrying out field management, at least comprising intertilling and weeding, irrigation and drainage, prevention of water logging, fertilizer application, pest control, interplanting, crop rotation and the like, and carrying out crop rotation with the following plants such as radix pseudostellariae, mint and iris tectorum; (6), harvesting and processing, namely, harvesting from July to October, and processing by adopting manners of drying, airing and drying in the shade. The polygonum capitatum as the medicinal material of the Relinqing granule, planted by adopting the method disclosed by the invention, is capable of generating huge economic benefit and social benefit.

The present invention relates to a kind of fresh polygonum capitatum or dried polygonum capitatum extract and its medicine composition preparation. Said invention uses water, 75% ethyl alcohol and 95ethyl alcohol and utilizes CO2 supercritical extraction method to separately extract whole plant of polygonum capitatum, its aerial parts, leaf, seed, stem and root, and make activity research, and makes said extract into the medicine composition preparation tablet with obvious effect for curing the diseases of pyelonephritis and prostatilis, etc.

Polygonum capitatum extract and medicinal composition preparation thereof

The process of planting Polygonum capitapum includes seed collection, raising seedling, culturing, harvesting, treatment and other technological links. The artificially planted Polygonum capitapum has the same biological characteristics and pharmacological characteristics with wild Polygonum capitapum, and may be used in extracting medicine component as that from wild Polygonum capitapum.

Method for planting polygonum capilalum

The present invention relates to the extractive of fresh and dry Polygonum capitapum and its preparation process, use and medicine composition. The whole weed, leaf, seed, stem and root of Polygonumcapitapum are extracted with water, 75 % concentration alcohol, 95 % concentration alcohol and CO2 in supercritical state, and the activity of the extractive is researched. The extractive of Polygonum capitapum has obvious effect in antibiosis, diminishing inflammation, stopping pain, diuresis, and treating pyelonephritis, prostatitis, calculus, etc.

Polygonum capilalum extract , iIts preparation method and use

A method for testing the bioactivity of Touhualiao, its extract and its products includes precisely weighing Touhualiao, its extract, or its product, loading in centrifugal tube, adding less physiological saline, ultrasonic oscillating, proportionally adding physiological saline, injecting it into mouse body, waiting for 5 min, coating croton oil as phlogistic agent, waiting for 4 hr, killing the mouse, punching left and right ear blocks, weighing them to obtain weight difference and calculate the swelling suppressing rate.
