Embodiment 1

[0020] This embodiment includes the following steps:

[0021] (1) After drying 10kg of fresh Pistacia chinensis leaves naturally, use supercritical CO 2 The essential oil of Pistacia chinensis was extracted by the fluid extraction method, the extraction pressure was 50MPA, the extraction time was 5 hours, and the temperature was 70°C to obtain 30g of essential oil, which was a yellow transparent oily liquid.

[0022] (2) After crushing the residues of Pistacia chinensis tissue extracted from the essential oil, sieve it, add it into methanol with a mass percentage concentration of 80% according to the solid-liquid ratio of 1:200g / ml, and extract it in a water bath at 95°C for 200min; at the same time, use Ultrasonic wave 10000W is used for auxiliary extraction; after the extract is filtered out, the methanol in the solution is removed by rotary evaporation, and the crude polyphenol extract is obtained by vacuum freeze-drying.

[0023] In this example, the yield of polyphenols ...

Embodiment 2

[0025] This embodiment includes the following steps:

[0026] (1) After drying 10kg of fresh Pistacia chinensis leaves naturally, use supercritical CO 2 The essential oil of Pistacia chinensis was extracted by the fluid extraction method, the extraction pressure was 10MPA, the extraction time was 1 hour, and the temperature was 30°C to obtain 20g of the essential oil, which was a yellow transparent oily liquid.

[0027] (2) After crushing the residues of Pistacia chinensis tissue extracted from the essential oil, sieve it, add it into propanol with a mass percentage concentration of 50% according to the solid-liquid ratio of 1:2g / ml, and extract it in a water bath at 20°C for 10 minutes; at the same time Ultrasonic wave 800W is used for auxiliary extraction; then, after filtering the extract, rotary evaporation removes propanol in the solution, and vacuum freeze-drying to obtain crude polyphenol extract.

[0028] In this example, the yield of polyphenols determined by the Fol...

Embodiment 3

[0030] This embodiment includes the following steps:

[0031] (1) After drying 10kg of fresh Pistacia chinensis leaves naturally, use supercritical CO 2 The essential oil of Pistacia chinensis was extracted by the fluid extraction method, the extraction pressure was 15MPA, the extraction time was 3 hours, and the temperature was 50°C to obtain 28g of essential oil, which was a yellow transparent oily liquid.

[0032] (2) Crush the pistachio chinensis tissue residue extracted from the essential oil, sieve it, add it into ethyl acetate with a mass percentage concentration of 60% according to the solid-liquid ratio of 1:50g / ml, and extract it in a water bath at 30°C for 20 minutes; At the same time, ultrasonic wave 100W is used for auxiliary extraction; after centrifugation to separate the extract solution, ethyl acetate in the solution is removed by rotary evaporation, and the crude polyphenol extract is obtained by vacuum freeze-drying.

[0033] In this example, the yield of p...

Abstract

The invention discloses a method for coproduction of pistacia chinensis bunge essential oil and polyphenol. The method comprises the following steps of: naturally airing pistacia chinensis bunge leaves; extracting the pistacia chinensis bunge essential oil by adopting a supercritical CO2 fluid extraction method; crushing pistacia chinensis bunge tissue residues obtained by extracting the essential oil; and carrying out polyphenol extraction. According to the method disclosed by the invention, source forest fostering residues are used as raw materials to carry out the coproduction of the pistacia chinensis bunge essential oil and the polyphenol; in a process of obtaining the high-quality essential oil, the subsequent extraction of the polyphenol is carried; two substances with high value and good application prospect are dug from forestry wastes, so that the comprehensive utilization value of an important energy plant pistacia chinensis bunge is greatly improved; the method has the very important meanings in accelerating the development of a biological energy source industry and improving the economic and social benefits of energy source plants.

Description

technical field [0001] The invention relates to a joint production technology of Pistacia chinensis, specifically a method for joint production of Pistacia chinensis essential oil and polyphenols. Background technique [0002] Pistacia chinensis, also known as Kaimu, is a deciduous woody oil and timber tree species of Anacardiaceae. It is one of the main tree species for the development of woody bioenergy in China. Pistacia native to my country, widely distributed, resistant to drought, salinity, barrenness, strong adaptability, can be developed in marginal land, suitable for large-scale afforestation. Biodiesel produced from Pistacia chinensis seed oil is clean renewable energy and a high-quality substitute for petroleum diesel. Therefore, the development of Pistacia chinensis energy forest is of great significance to solve the problem of oil resource shortage in my country. [0003] As a woody energy plant, Pistacia chinensis has the problem of a long childhood, and it ta...
