74 results about "Safrole" patented technology

Safrole is an organic compound with the formula CH₂O₂C₆H₃CH₂CH=CH₂. It is a colorless oily liquid, although impure samples can appear yellow. A member of the phenylpropenoid family of natural products, it is found in sassafras plants among others. Small amounts are found in a wide variety of plants, where it functions as a natural antifeedant. Ocotea pretiosa, which grows in Brazil, and Sassafras albidum, which grows in eastern North America, are the main natural sources of safrole. It has a characteristic "sweet-shop" aroma.

High performance liquid chromatography fluorescence detection method for simultaneously measuring four prohibited and limited additives in tobacco flavors and perfumes

The invention discloses a high performance liquid chromatography fluorescence detection method for simultaneously measuring four prohibited and limited additives in tobacco flavors and perfumes. The high performance liquid chromatography fluorescence detection method comprises the following steps: firstly performing oscillating extraction on the tobacco flavors and perfumes by using alcohol, standing to pass through a 0.45 micrometer organic phase filtering membrane to obtain a to-be-detected sample solution; and simultaneously preparing standard solutions of the four prohibited and limited additives, respectively performing detection analysis on the to-be-detected sample solution and the standard solutions by adopting a high performance liquid chromatography fluorescence detector, and then performing quantitative analysis by adopting an external standard method, figuring out contents of the four prohibited and limited additives in the tobacco flavors and perfumes, wherein the four prohibited and limited additives comprise sesamol, beta-naphthol, beta-asarone and safrole. According to the high performance liquid chromatography fluorescence detection method, simultaneous measurement of the four prohibited and limited additives in the tobacco flavors and perfumes is realized. Because special chromatographic columns for phenols are used, the detection time is relatively short; the fluorescence detector is adopted, the selectivity is relatively high, the matrix interference is relatively small, the detection limit is relatively low; no water removal is needed before treatment, and the relative simplicity is achieved in operation.

Process for preparing non-toxic extractive from asarum heterotropoides

The invention relates to a process for removing toxic and harmful components from herbal medicines and extracting effective components from the herbal medicines, in particular to a process for preparing non-toxic extractives from asarum heterotropoides, belonging to the field of pharmaceutical technology. The preparation process for preparing the non-toxic extractives from the asarum heterotropoides comprises the following steps of: decocting a whole asarum heterotropoides plant by using hot water for extraction; cooling filer liquor; adding HCl and NaOH to regulate a pH value; and removing the toxic components, i.e. volatile safrole and nonvolatile components, such as aristolochic acid and aconitine, nor-aconitine and the like, out of asarum heterotropoides medicinal materials and effectively retaining the effective components through the purification steps of cation exchange resin, anion exchange resin, and the like. The invention can simultaneously remove multiple toxic and harmful components contained in the asarum heterotropoides medicinal materials together, obviously shorten the production period and reduce the production cost; in addition, a detoxification process has the advantages of strong compatibility, simple process, low energy consumption and resource saving without environment pollution in the production process.

Sodium phosphate oral solution composition and preparation method thereof

The invention discloses a sodium phosphate oral solution composition and a preparation method of the sodium phosphate oral solution composition. The raw materials for preparing the oral solution composition comprise disodium hydrogen phosphate, ginger juice, lemon juice, phosphoric acid, glycerin and purified water, and the addition amounts of the raw materials for preparing each liter of the oral solution composition are as follows: 2.5 to 250g of phosphoric acid, 5 to 7g of the ginger juice and 4 to 6g of the lemon juice; the weight of disodium hydrogen phosphate is 1.4-1.6 times of that of phosphoric acid, and the weight of the glycerin is 4%-6% of that of phosphoric acid. The preparation comprises the following steps: firstly adding disodium hydrogen phosphate and glycerin into purified water, then adding the ginger juice and lemon juice, then adding phosphoric acid, stirring heating to 60-65 DEG C, digesting for 0.5-1 hour, finally adding purified water to fix volume and uniformly stirring. The sodium phosphate oral solution composition disclosed by the invention can effectively inhibit ginger to generate and transform carcinogen safrole and promote a gastrointestinal medicine guiding effect of ginger components, has an obvious synergistic effect and a good intestine cleaning effect, can further relieve gastrointestinal discomfort, can be used as a mild and safe intestine cleaning product and further can be used as a medicine, food and drink.
