Embodiment 1

[0048] Formula: (weight percentage)

[0049] Taxus cuspidata: coniferous plants = 1:1.3;

[0050] The coniferous plants are selected from Korean pine;

[0051] Preparation:

[0052] (1) After picking fine branches and leaves from Northeast yew and coniferous plants, wash them with clean water, cut into short branches and leaves, and drain the water. Crush the drained branches and leaves with a coarse crusher, pass through a 20-mesh sieve, and seal the under-sieve for use.

[0053] (2) Mix the crushed yew and conifer materials evenly, add water twice the weight of the raw materials, and then add NaCl to increase the osmotic pressure of the extraction system. In the system, the weight concentration of NaCl is 1% at room temperature. Soak for 2h for extraction, condense and collect the distilled vapor to obtain condensate, the collection time is 3h;

[0054] (3) Add petroleum ether to the distillate for extraction. After drying the extract with anhydrous sodium sulfate, use a rotary evapo...

Embodiment 2

[0063] Formula: (Quality)

[0064] Taxus cuspidata: coniferous plants = 1:1.4;

[0065] The coniferous plants are selected from Pinus sylvestris;

[0066] Preparation:

[0067] (1) After picking fine branches and leaves from Northeast yew and coniferous plants, wash them with clean water, cut into short branches and leaves, and drain the water. Crush the drained branches and leaves with a coarse crusher, pass through a 20-mesh sieve, and seal the under-sieve for use.

[0068] (2) Mix the crushed yew and coniferous plant materials uniformly, add 4 times the weight of the raw materials, and then add NaCl to increase the osmotic pressure of the extraction system. In the system, the weight concentration of NaCl is 5% at room temperature. Soak for 2h for extraction, condense and collect the distilled vapor to obtain condensate, the collection time is 5h;

[0069] (3) Add dichloromethane to the distillate and extract. After drying the extract with anhydrous sodium sulfate, use a rotary evapo...

Embodiment 3

[0073] Example 3 Composition

[0074] Weight percentage:

[0075] Compound essential oil of Northeast yew and coniferous plants 10%

[0076] Soy wax 90%

[0077] The preparation method of the present invention is as follows:

[0078] The preparation method of the compound essential oil of Northeastern yew and coniferous plants is the same as that of Example 1, and then it and the carrier soy wax are heated to 60°C to melt, and then cooled to 40-45°C and added to the Northeast yew and conifers. The plant compound essential oil is mixed according to the formula, the wax core is added, and it is poured into a wax cup to cool, to obtain the composition aroma wax containing the compound essential oil of cuspidata.

[0079] Using the method specified in GB / T18883-2002 "Indoor Air Quality Standard", the results are as follows:

Abstract

The invention discloses composite essential oil prepared from taxus cuspidata and coniferous plants and application of the composite essential oil. The composite essential oil prepared from taxus cuspidata and coniferous plants is prepared from taxus cuspidata and coniferous plants at the weight ratio of 1:1-1:3, and the composite essential oil can be used for preparing aroma essential oil, aroma candles and air fresheners for improving indoor air quality or preparing skin essential oil soap. The composite essential oil can effectively purify air, improve air quality and effectively reduce indoor methanal, benzene, methylbenzene, dimethylbenzene, total volatile organic compounds and ammonia content.

Description

Technical field [0001] The invention relates to a compound essential oil for improving air quality, in particular to a compound essential oil of Northeast yew and coniferous plants. Background technique [0002] The quality of air directly affects people's health. At present, many patents disclose technologies that can improve air quality, including methods such as the use of negative ion generators. [0003] Chinese patent [application number: 201110166307.5] discloses a yew incense, which is characterized in that it is made from yew roots or stems or branches or leaves or seeds or skins or fruits, ground into powder or shredded or sliced, and then Mix with binder to make yew incense. This solution can effectively improve indoor air quality by heating the yew incense, avoid damage to some beneficial components in the yew incense, and make some components in the yew incense enter the air at a faster speed. However, the plan did not clearly specify the specific components of yew ...
