Embodiment 1

[0021] A kind of extracting method of arborvitae extract, comprises the following steps:

[0022] S1. Take leaves of orientalis orientalis, wash and dry naturally in the shade, then dry at constant temperature for 4 hours, crush and sieve;

[0023] S2. Add 95% ethanol according to the ratio of solid to liquid of 1:10, and soak for 2 hours;

[0024] S3. Ultrasonic treatment of the feed liquid at 70 °C at 40 Hz for 1 h;

[0025] S4. Use a supercharger to filter the feed liquid through the reverse osmosis membrane module. After filtration, the permeate is discharged, and the filtered feed liquid is subjected to ultrasonic treatment according to the above method, and the feed liquid is concentrated for 3 times to obtain side Cypress extract.

Abstract

The invention discloses an extracting method for oriental arborvitae extract. The extracting method is characterized by including the following steps that S1, oriental arborvitae leaves are washed, naturally dried in the shade, dried at a constant temperature for 4h, crushed and then sieved; S2, 95% ethyl alcohol is added according to the material-liquid ratio of 1:10, and soaking is carried out for 2h; S3, material liquid is subjected to ultrasonic treatment for 1h with 40 Hz ultrasonic waves at the temperature of 70 DEG C; and S4, a pressurizer is used for enabling the material liquid to pass through a reverse osmosis film assembly to be filtered, after filtering, permeate liquid is discharged, filtered material liquid is subjected to ultrasonic treatment according to the method circularly for three times so as to achieve material liquid concentration, and thus the oriental arborvitae extract is obtained. According to the extracting method for the oriental arborvitae extract, ultrasonic extraction is utilized, the pressurizer is adopted to enable the material liquid to pass through the reverse osmosis film assembly to be filtered and purified, and thus the obtained oriental arborvitae extract is high in purity.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to an extraction method of arborvitae extract. Background technique [0002] Arborvitae leaves, also known as cypress leaves, clump cypress leaves, cypress, cloud cypress, etc., are the dry young branches and leaves of the cypress plant Arborvitae. Traditional Chinese medicine believes that the leaves of oriental cypress leaves are fragrant, bitter and astringent, slightly pungent, and have the effects of cooling blood and stopping bleeding, dispelling wind and dampness, reducing phlegm and cough, reducing swelling and dispelling toxins. It is often used clinically to treat hemorrhage, rheumatic arthralgia, and high blood pressure , Cough, asthma and scald embolism. In Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty, "it is a long-lived tree, so it can be eaten. Taoism uses it to order soup and drink it" records, and summarizes the records of the efficacy...
