68 results about "Raphanin" patented technology

Raphanin is the main sulfur component found in radish seeds of Raphanus sativus and is also found in broccoli and red cabbage. It was first described by G. Ivanovics and S. Horvath in 1947. Raphanin inhibits activity of viruses, some fungi and various bacteria including Staphylococcus, Streptococcus, Pneumococcus and Escherichia coli (see table). The effect is stronger against Gram-positive than Gram-negative bacteria and against DNA than RNA viruses; it is suppressed by serum and by sulfur compounds such as hydrogen sulfide, mercaptoacetic acid, cystine and glutathione. The antibacterial, antifungal and antiviral effects from consuming radishes were recognized in traditional Chinese medicine. However, in the abstract to his 1947 paper, Ivanovics noted that because raphanin is highly toxic, it did not "hold the promise of a useful therapeutic agent".

Preparation method of pH sensitiveness raphanin chitosan microsphere

The invention discloses a preparation method of a pH sensitiveness raphanin chitosan microsphere. The preparation method comprises the following steps: 1) dissolving chitosan powder into an acetic acid solution; 2) taking a raphanin water solution and adding into the acetic acid solution; and 3) dropping a sodium tripolyphosphate solution into the mixture liquid obtained in the step 2) so as to obtain the raphanin-chitosan microsphere. The preparation method of the pH sensitiveness raphanin chitosan microsphere is reasonable in design, and the microsphere is prepared by using an ionic cross-linking method in a mode that the chitosan is taken as a carrier and the sodium tripolyphosphate is taken as a cross-linking agent, the experiment is simple and mild, and no organic solvents are used, so that the method is safe and environmental-friendly, a drug carrying microsphere solution of which the average particle size is 500 nm is successfully prepared, and moreover the prepared microsphere solution is good in stability and has no great change in particle size after being placed for a long time; under the acidic condition, the raphanin can be released more easily, and the higher the pH value is, the longer the releasing time is, and therefore the microsphere is an ideal slow release formulation of the raphanin.

Extraction method of raphanin

The invention discloses an extraction method of raphanin. The extraction method comprises the following steps: preparing broccoli powder from stems and/or leaves of broccoli, mixing 2 parts of broccoli powder, 15 to 25 parts of external mustard seed enzyme solution and 10 parts of phosphoric acid buffering solution with the pH of 4.0 to 6.0, forming a primary mixed solution, successively performing the enzymolysis, freeze drying, extraction and suction filtering for the primary mixed solution, obtaining raphanin extraction solution, performing the rotary evaporation for the raphanin extractionsolution to obtain raphanin extract, re-dissolving the extract by using 50 percent acetonitrile, chromatographically collecting by using half prepared liquid phase, and obtaining a raphanin pure product. The proportion of the broccoli powder, the external mustard seed enzyme liquid and the phosphoric acid buffering solution is g: mL: mL. The raphanin is extracted from a broccoli byproduct, so that the byproduct utilization rate can be greatly improved, the additional value of the broccoli can be increased, and the resource waste can be reduced. The process parameters are optimized by virtue of a single-factor experiment and response surface experiment, and a raphanin extraction method which is simple in operation, simple in equipment, rapid, high in efficiency, and high in product puritycan be obtained.

Broccoli leftover extractive and preparation method thereof

The invention discloses a broccoli leftover extractive and a preparation method thereof. The method comprises the following steps of: (1) pulping broccolis and carrying out ultrasonic-assisted enzymolysis on pulp; and (2) extracting broccoli raphanin and flavonoid compounds, respectively adding ethanol and water to carry out microwave-assisted reflowing extraction, combining extraction solutions obtained by two times of reflowing extraction, recycling alcohol by decompressing, continually concentrating the recovered alcohol to be paste, and drying the paste in vacuum to obtain the broccoli leftover extractive. The preparation method disclosed by the invention has the characteristics that a complex enzyme preparation, ultrasonic-assisted extraction and microwave-assisted extraction are applied to the extraction of effective components in broccoli leftovers; and compared with the prior art, the preparation method improves the additional value of the broccoli leftovers greatly and the yield of the raphanin and flavonoid compounds, and also has the characteristics of low energy consumption, moderate extraction condition and low cost. The broccoli leftover extractive can be widely applied to the fields of bulk pharmaceutical chemicals, biochemical engineering and health-care foods, and has wide market prospect.

ActiveCN105713937AFill in the gaps in secretory researchLess investmentOrganic chemistryFermentationLiquid mediumRaphanin
The invention relates to a method for obtaining raphanin from a broccoli hairy root culture system. The method comprises the following steps: (1) inoculating broccoli hairy root to a liquid medium, carrying out proliferation culture and freeze drying, and grinding into powder, thus obtaining lyophilized hairy root powder; (2) grinding newly harvested mustard seeds, carrying out ultrasonic oscillation extraction, and carrying out suction filtration to remove impurities, thus obtaining a crude enzyme; (3) adding the crude enzyme into the lyophilized hairy root powder, carrying out enzymolysis and ultrasonic oscillation extraction, and carrying out vacuum filtration to remove impurities, thus obtaining raphanin crude extraction liquid; (4) concentrating the raphanin crude extraction liquid, and extracting to obtain an ethyl acetate phase A; (5) extracting the liquid medium, thus obtaining an ethyl acetate phase B; (6) mixing the ethyl acetate phase A and the ethyl acetate phase B, and carrying out vacuum concentration and dissolution on the mixture, thus obtaining raphanin methanol solution; (7) carrying out vacuum concentration on the raphanin methanol solution, thus obtaining a raphanin crude extract; and (8) drying the raphanin crude extract to obtain a raphanin crude product with the purity being 5-30%. The method is simple and efficient.
