Embodiment 1

[0034] 1.1 Exploration of extraction conditions

[0035] 1.1.1 The influence of extraction time on the extraction rate of oleoresin

[0036]Accurately weigh 200g of pulverized betels, put them into an extraction kettle, and carry out single-factor experiments with extraction times of 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 h at an extraction pressure of 20 MPa and a temperature of 40 °C, and collect False oleoresin, after weighing, calculates the extraction rate of False oleoresin, repeats above steps 3 times.

[0037] 1.1.2 Effect of extraction pressure on the extraction rate of betel oleoresin

[0038] Accurately weigh 200g of pulverized betels, put them into an extraction kettle, and carry out single-factor experiments with extraction pressures of 15, 20, 25, 30, and 35 MPa at an extraction time of 1.5 hours and a temperature of 40°C to collect betels Oleoresin, after weighing, calculates the extraction rate of the oleoresin of False Betel, repeats above steps 3 times.

Embodiment 2

[0067] Weigh 2.7kg of dry powder of betel stems and leaves crushed to 40 meshes (the water content of betel stems and leaves is 2%), put it into a 10L extraction kettle, adjust the extraction pressure to 20MPa, the extraction temperature to 50°C, and the flow rate of carbon dioxide to 40L / h. I pressure is 6.5MPa, separation kettle I temperature is 65°C, separation kettle II pressure is 5MPa, separation kettle II temperature is 35°C, extraction time is 2h, take out the oleoresin from separation kettle I and separation kettle II and combine to obtain 109.19g, the extraction rate is 4.04%.

Embodiment 3

[0069] Take by weighing 2.7kg of dry powder of betel stems and leaves crushed to 40 objects (the water content of betel stems and leaves is 6%), put it into a 10L extraction kettle, adjust the extraction pressure to 25MPa, the extraction temperature to 55°C, and the frequency of the carbon dioxide pump to be 60L / h. The pressure of the separation kettle I was 6.0MPa, the temperature of the separation kettle I was 50°C, the pressure of the separation kettle II was 4.5MPa, the temperature of the separation kettle II was 40°C, and the extraction time was 3h. The oleoresin was taken out from the separation kettle I and the separation kettle II and combined to obtain 111.51g. The extraction rate is 4.13%.

Abstract

The invention discloses a method used for extracting piper sarmentosum oleoresin, and obtained piper sarmentosum oleoresin. According to the method, supercritical carbon dioxide extraction is adopted; temperature of the processing process is controlled to be low; effective ingredients of piper sarmentosum oleoresin are not destroyed; fragrance of piper sarmentosum oleoresin obtained via extraction is pure, quality is stable, no solvent is left, extraction rate is relatively high, no component is added, and obtained piper sarmentosum oleoresin is a pure natural product, and can be used for fields such as food, medicine, and animal fodder.

Description

technical field [0001] The invention relates to a supercritical carbon dioxide extraction technology, in particular to a method for extracting betel oleoresin by using the supercritical carbon dioxide extraction technology and the betel oleoresin directly obtained by the method. Background technique [0002] Piper sarmentosum (Piper sarmentosum Roxb.), a plant of the genus Piper in the family Piperaceae, is also known as piper sarmentosum, Piper sarmentosum Roxb. and so on. False betel is warm in nature and pungent in taste. It has the functions of expelling wind and cold, promoting qi and relieving pain, dissipating blood stasis, dehumidifying toxins, and warming the stomach. Diarrhea, postpartum edema, bruises, toothache, hemorrhoids and other diseases. The main functional components of Pseudonymus are almost all present in its oleoresin, which contains a variety of pharmacologically active components such as asarone, cis-caryophyllene, hydrogenated cinnamic acid and β-s...
