1520 results about "Berberine" patented technology

Berberine is a quaternary ammonium salt from the protoberberine group of benzylisoquinoline alkaloids found in such plants as Berberis (e.g. Berberis vulgaris – barberry, Berberis aristata – tree turmeric, Mahonia aquifolium – Oregon-grape, Hydrastis canadensis – goldenseal, Xanthorhiza simplicissima – yellowroot, Phellodendron amurense – Amur cork tree, Coptis chinensis – Chinese goldthread, Tinospora cordifolia, Argemone mexicana – prickly poppy, and Eschscholzia californica – Californian poppy). Berberine is usually found in the roots, rhizomes, stems, and bark.

Berberine electrostatic composite and preparation method of berberine electrostatic composite

The invention discloses a berberine electrostatic composite and a preparation method of the berberine electrostatic composite, which are applied to medical and health industries. The berberine electrostatic composite is prepared from anionic surfactant and berberine or berberine salt by compositing; the molar ratio of the anionic surfactant to the berberine or berberine salt is 1 to 0.5-10; the molar ratio of anion to the berberine salt is 1 to 1; the anionic surfactant is one or more of alkyl sulfate or alkyl sulfonate or fatty acid salt; the alkyl sulfate is one or more of sodium cholesteryl sulfate, lauryl sodium sulfate and deoxysodium cholate; the alkyl sulfonate is one or more of sodium heptanesulfonate and sodium dodecyl sulfate; the fatty acid salt is one or more of sodium caprate and sodium enanthate, and the berberine and berberine salt are obtained by chemical synthesis or by extracting traditional Chinese medicine. The berberine is prepared into the berberine electrostatic composite to increase the biological membrane penetrating ability of the berberine and improve the oral bioavailability of the berberine, and the berberine electrostatic composite plays a significant treatment role on important chronic metabolic disorder diseases such as diabetes mellitus, complication of the diabetes mellitus, hyperlipidemia and the like.

Berberine plant source insecticide and preparation method thereof

The invention relates to a berberine plant source insecticide and a preparation method thereof. The insecticide comprises the following raw materials in parts by weight: 40-50 parts of berberis root, 1-2 parts of phellodendron bark, 45-50 parts of purple common perilla and 2-3 parts of castor. The berberine plant source insecticide takes berberine in the berberis root and phellodendron bark as the insecticidal active component; and since berberine has photoactive toxicity for pests, and the toxicity of the berberine plant extract for pests is enhanced when the berberine plant extract is degraded under the activation of light, the invention enhances the drug effect of insecticide, prevents enduring residence in the environment and conforms to environment concordance required by no-pollution pesticides. The product of the invention has the advantages of no toxicity, no residue, wide materials sources and low production cost, has the effects of anesthetization, contact killing, stomach toxicity, systemic action and the like, has favorable integrated control effects of disinsection and bacteriostasis, can be widely used in the fields of agriculture, forestry, animal husbandry and the like, and is especially suitable for production of traditional Chinese medicinal materials, organic food, green food and no-pollution food.

Berberine organic acid salt, berberine organic acid salt inclusion compound and preparation methods thereof

The invention provides a berberine organic acid salt, a berberine organic acid salt inclusion compound and preparations method thereof. The berberine organic acid salt consists of an alkali base and a salt ligand, wherein the alkali base is a jamaicin alkali base; the salt ligand is an acid radical of organic acid; the mole ratio of the alkali base to the acid radical of organic acid is 1:1; and the berberine organic acid salt inclusion compound consists of an inclusion base material and the berberine organic acid salt. The method for preparing the berberine organic acid salt comprises the following steps of: neutralizing solution of jamaicin and solution of organic acid into salt; crystallizing the salt; and filtering, leaching and drying the crystallized salt so as to obtain the berberine organic acid salt. The method for preparing the berberine organic acid salt inclusion compound comprises the following steps of: dissolving the inclusion base material; adding the berberine organic acid salt into the dissolved inclusion base material for dissolving and inclusion; cooling and standing reaction liquid to separate coprecipitate out; leaching the coprecipitate with acetone; and drying a filter cake so as to obtain the berberine organic acid salt inclusion compound. The berberine organic acid salt and the berberine organic acid salt inclusion compound provided by the invention have the advantages of high bioactivity, small dosage and high dissolubility. The preparation methods have the advantages of simple process, high product purity, easy operation control, simple equipment and easy realization of industrialized production.

Preparation methods of sustained-release microcapsule and sustained-release composite membrane for inhibiting monilinia fructicola

The invention discloses preparation methods of a sustained-release microcapsule and a sustained-release composite membrane for inhibiting the monilinia fructicola. The preparation method of the sustained-release microcapsule comprises the following steps: the chitosan and the berberine are weighed, the mass ratio between the chitosan and the berberine is 9-11:0.22-0.28, the acetate solution is added, then the chitosan and the berberine are sufficiently swelled to obtain berberine-chitosan solution after stirring for dissolving, standing and air bubble removal, and the berberine-chitosan solution is added in the soybean oil containing span 80, stirred at the constant temperature of 40-50 DEG C and then emulsified for 28-32 min to form a W/O system; the glutaraldehyde solution is added for stirring for 2.5-3.5 hours, and the centrifuging is carried out so that the microcapsule is fully settled; and the preparation liquid on the upper layer is obliquely taken, the obtained microcapsule is washed with petroleum ether for 3-5 times and then dried for 23-25 hours under the vacuum at the temperature of 48-52 DEG C. The invention also provides the preparation method for the sustained-release composite membrane for inhibiting the monilinia fructicola. Both the microcapsule and the composite membrane have the sustained-release effects and have no toxic side effect to the environment and the plants since the berberine is a native compound.

Method for observing microscopic structures inside plant roots

The invention relates to a method for observing microscopic structures inside plant roots, which is capable of effectively solving the problem of utilizing a microscope to clearly observe the structures inside the plant roots. The method comprises the steps of digging out the plant roots, washing, shearing the plant roots into small sections, fixing the plant roots by methanol, and then embedding by a sepharose solution, cooling, condensing, trimming into small blocks, after freehand section, placing the small blocks into distilled water in a container, performing lactic acid clearing, covering, dyeing via berberine or fluorescein, bleaching by the water, performing poststaining via toluidine blue O or sarranine O, bleaching by the water, performing water seal, observing and photographing via an inverted fluorescence microscope, and obtaining a clear image. The method can be used for observing the microscopic structures inside the plant roots, thereby being effectively used for the research on classification, auxanology, ecology and physiology of medical plants. The method disclosed by the invention has the advantages of simple method, easiness in operation, low cost, low working capacity, high success rate, and good effect, thereby being capable of being used for the research on morphological anatomy of the roots. The method is simpler and more effective for the thinner root sections of the plants.
