Disclosed is a method for joint recovery of pectin from citrus peels and alkaline/acidic processing water from citrus canning, including the following steps: adding fresh citrus fruit peels to alkali/acid processing water from citrus fruit canning for extracting; filtering the resulting mixture, adding to the resulting filtrate 95% ethanol 1 to 3 times the volume of the filtrate, and then adjusting the pH to a range of 3.5 to 7, followed by standing for 10 minutes to 4 hours; filtering the product after standing, washing the resulting precipitate with 50% to 70% ethanol, and drying and crushing, thereby obtaining pectin. The method makes full use of waste resources from citrus fruit canning, solves the problem of pollution by processing discharge water, and has the advantages of saving the preparation cost of pectin from citrus peels, and improving the solubility of recovered pectin.

Polydisperse and charged polysaccharides are fractionated into low polydispersity fractions (preferably having pd<1.1), each containing species within a narrow range of molecular weights. An aqueous solution of the polydisperse polysaccharides is contacted with an ion exchange resin in a column and the polysaccharides are subjected to selective elution by aqueous elution buffer. The selective elution consists of at least 3 sequential elution buffers having different and constant ionic strength and/or pH and in which the subsequent buffers have ionic strength and/or pH than those of the preceding step. The new preparations are particularly suitable for the production of PSA-derivatised therapeutic agents intended for use in humans and animals.

The present invention relates to a method for preparing a chitosan matrix having good mechanical properties comprising the steps of a) preparing a solution of chitosan, b) pouring the solution of a) into a mould in order to form a layer, c) lyophilizing the layer of b) in order to obtain a matrix of chitosan, d) sterilizing the matrix obtained in c) by water vapor treatment. The invention also relates to the matrices obtained and to surgical implants comprising such matrices. The invention further relates to a method for increasing the suture retention strength of a chitosan matrix obtained by lyophilization of a chitosan solution, and to a method for for decreasing the solubilization rate in hydrochloric acid of a chitosan matrix obtained by lyophilization of a chitosan solution, comprising the step of sterilizing said matrix by a water vapor treatment.

The present invention provides a method to prepare polysaccharides from Hirsutella sinensis. The prepared polysaccharides reduce body weight and fat accumulation in laboratory animals, and can therefore be used to prevent and treat obesity.

The invention relates to the use of a crushed material obtained from at least one part of rocket plants, for example of the genera Eruca (Eruca sativa, Eruca vesicaria, etc.), Diplotaxis (Diplotaxis erucoides, Diplotaxis tenuifolia, Diplotaxis muralis, etc.), Bunias (Bunias erucago, Bunias orientalis, etc.), Erucastrum (Erucastrum nasturtiifolium, Erucastrum incanum, etc.) or Cakile, in order to promote plant growth or root growth.

The usefulness of the product of the invention has also been proven in conditions of stress for the plant (for example water stress).

The crushed material is obtained from leaves, seeds and/or flowers of plants.

In some embodiments, at least one active ingredient is obtained by aqueous extraction, solvent extraction, or oil extraction, or by extraction of oil cakes or pastes.

In some embodiments, a composition obtained from the crushed material obtained from at least one part of rocket plants is formulated in the form of powder, granules, dispersible granules or slow-diffusion granules, or in liquid form.

The present invention relates to compositions comprising fractionated alkylated cyclodextrm compositions having a single degree of substitution, and processes for preparing and using the same.

The present invention provides a Peyer's patch activator containing a polysaccharide obtained from sugar cane as an active ingredient, wherein the polysaccharide contains α-glucan as a main component and has a peak molecular weight within a range of 720,000 to 1,080,000, with a proportion of glucose in all component sugars being 80% or more, and proportions of nonreducing terminal glucose and α-1,6-linked glucose being 20 to 30% and 15 to 25%, respectively.
