Problems solved by technology

The preparation method comprises 50-95% ethanol extraction, low-polarity solvent extraction, and centrifugation to obtain the active extract of Taxus chinensis, but the total flavonoid content of this method still needs to be improved, and the obtained extract is not a volatile oil, so it is not suitable as a perfume. How to develop yew solid perfume has no related reports

Embodiment 1

[0026] The yew solid perfume of the present embodiment and preparation method thereof, comprises the following steps:

[0027]Step 1. Pretreatment of raw materials: select fresh yew branches and leaves, wash them, dry them in an oven, control the temperature below 60°C, and then pulverize them with a particle size of 30-40 mesh;

[0028] Step 2, extraction of volatile oil: put 1 kg of crushed yew branches and leaves into 35°C Titian petroleum ether for two consecutive extractions, adding 15kg Titian petroleum ether each time, and the extraction time is 4 hours for the first time. 2h for the second time. Combine the extract after filtering, remove the residue, and obtain the extract containing volatile oil;

[0029] Step 3, post-treatment of the extract: put the extract into a distiller to evaporate the petroleum ether therein to obtain an extract; add 5 times the weight of the extract to 75% ethanol to dissolve, and cool at -20°C 12h, filter off the residue to obtain the eth...

Embodiment 2

[0032] The yew solid perfume of the present embodiment and preparation method thereof, comprises the following steps:

[0033] Step 1. Pretreatment of raw materials: select fresh yew branches and leaves, wash them, dry them in an oven, control the temperature below 60°C, and then pulverize them with a particle size of 30-40 mesh;

[0034] Step 2, the extraction of volatile oil. Put 1 kg of crushed yew branches and leaves into Titian petroleum ether at 45°C for two consecutive extractions, adding 20 kg of Titian petroleum ether each time, and the extraction time is 3 hours for the first time and 1 hour for the second time. Combine the extract after filtering, remove the residue, and obtain the extract containing volatile oil;

[0035] Step 3, post-processing of the extract. Put the extract in a distiller to distill off the petroleum ether to obtain an extract; add 3 times the weight of the extract to 90% ethanol to dissolve, cool at -20°C for 24 hours, filter off the residue,...

Abstract

The invention discloses a preparation method of yew solid perfume, including the steps of pretreatment of raw materials, leaching of volatile oil, post-treatment of extract solution and preparation of microcapsule solid perfume; The solid perfume obtained by the method; the present invention makes full use of yew resources, the process is simple, and the cost is low. The obtained yew solid perfume absorbs the essence of concentrated yew, has the unique fragrance of the yew forest, and has a good slow-release effect , long-lasting fragrance, easy to carry; the solvent Titian petroleum ether selected by the solvent extraction method has relatively large solubility and greater diffusion degree for the active ingredients of Taxus chinensis, and Titian petroleum ether is easy to recycle. The dissolution amount of the ingredients is small, so as to facilitate the concentration and purification of volatile oil; the composite wall material of β-cyclodextrin + maltodextrin can not only improve the embedding rate of yew microcapsules, but also achieve the improvement of yew microcapsule membrane compactness effect.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a yew solid perfume. Background technique [0002] The invention of perfume originally originated from the needs of ancient people to cover and improve body odor. In order to meet these requirements, people made purses of mixed substances such as spice buds and carried them with them. Due to the limited content, the aroma of the purse will dissipate over time, and the fragrance source needs to be replenished. Then, people extract or synthesize the spices to make liquid products with higher content of single or multiple components, which only need to be sprayed or coated to improve the smell. Due to the good volatility of the liquid perfume, it has a good diffusion radius, and the release is also very fast, but the lasting power is insufficient. Along with the appearance of new invention, people have also proposed that various solid releases fragrance as perfume card, product...
