Problems solved by technology

However, the steam direct distillation method requires high temperature, takes a long time, and the yield is low, and the heat-sensitive components in the components are easily destroyed
And the method yield of Ainaxiang raw material→Ai powder→Aina sesame oil is higher, which is more suitable for industrial production, but in the extraction process, there is the operation of first extracting Ainaxiang raw material and then extracting Aina sesame oil, which is not conducive to Comprehensive Analysis and Utilization of Active Components of Aina Sesame Oil

Embodiment 1

[0032] Weigh 500g of Aina japonica leaves that were naturally dried in the shade, crush them before use, pass through a 40-mesh sieve, put them in a 5L distillation device, add 3500mL of distilled water, ultrasonicate for 20 minutes, and soak for 3 hours. Under the condition of a vacuum of 0.06Mpa, turn on the low-temperature circulating water pump (10°C) and heater (45°C), reflux in a slightly boiling state, and replenish water at the same time, reflux for 2 hours, turn off the heater, and continue to cool the condensed water for 10 minutes. Collect 5.12 g of crystals adhered in the condenser and aromatic water collection device; collect 4100 mL of aromatic water, extract with an equal volume of petroleum ether for 1 hour, separate the liquids, add anhydrous sodium sulfate to the petroleum ether phase to dry, and heat in a water bath (30 ℃), petroleum ether was recovered under reduced pressure, and 11.23 g of a yellow oily substance was obtained, and the crystallization and the ...

Embodiment 2

[0034] Weigh 500g of fresh Aina japonica leaves, crush them before use, pass through a 10-mesh sieve, put them into a 5000mL distillation device, add 3000mL of distilled water, sonicate for 10 minutes, and soak for 1 hour. Under the condition of a vacuum of 0.1Mpa, turn on the low-temperature circulating water pump (15°C) and the heating device (85°C) to make it reflux, replenish water at the same time, reflux for 5 hours, turn off the heater, and continue to cool the condensed water for 10 minutes. Collect the adhered crystals in the condenser and the aromatic water collection device to be 4.82g; collect the aromatic water to obtain 4800mL, extract with an equal volume of petroleum ether for 1.5 hours, separate the liquids, add anhydrous sodium sulfate to the petroleum ether phase to dry, and heat in a water bath (35 ℃), petroleum ether was recovered under reduced pressure, and 12.53 g of a yellow oily substance was obtained, and the crystallization and the yellow oily substan...

Embodiment 3

[0036] Weigh 500g of Aina japonica leaves dried at 50°C, crush them before use, pass through an 80-mesh sieve, put them into a 5000mL distillation apparatus, add 3500mL of distilled water, ultrasonicate for 60 minutes, and soak for 6 hours. Under the condition of a vacuum of 0.08Mpa, turn on the low-temperature circulating water pump (5°C) and the heating device (65°C) to make it reflux, replenish water at the same time, reflux for 8 hours, turn off the heater, and continue to cool the condensed water for 10 minutes.

Abstract

The invention discloses a method for extracting Blumea balsamifera oil. The method comprises the following steps: 1) mixing water and Blumea balsamifera raw material by a weight ratio of 6:1-12:1, conducting ultrasonic treatment for 10-60 min, and then immersing the mixture at room temperature for 0.5-6 h; 2) heating under vacuum conditions, and extracting for 2-8 h with slight boiling water and a condensing temperature at 5-15 DEG C; 3) collecting crystals and aromatic liquid water produced from condensation, extracting the aromatic liquid with an organic solvent in a same volume for 1-3 h, separating the liquid, and recovering an organic phase to obtain a yellow oil matter; and 4) mixing the crystals and the yellow oil matter to obtain the Blumea balsamifera oil. According to the method, decompression is conducted in the extraction of Blumea balsamifera oil to reduce temperature required for boiling of the solution, thus reducing loss of components without high temperature intolerance in the Blumea balsanifera; and the operation is simple and can reduce the loss in complex operation, so as to improve the quality and yield of the Blumea balsamifera oil.

Description

technical field [0001] The invention relates to the field of natural products, in particular, the invention relates to a method for extracting Aina sesame oil. Background technique [0002] Ainaxiang is the fresh or dry aerial part of Ainaxiang (Blumea balsamifera (L.) DC.), aliased as Dafengai, Borneolum, and Jiafengai, etc. It is a famous Li nationality medicine in my country. The name of Li medicine "Nalong" is recorded in "Kaibao Materia Medica", "Compendium of Materia Medica" and "Lingnan Caiyaolu" and other herbal classics. It is clinically used to treat wind-cold cold, cold-damp diarrhea, abdominal pain, borborygmus, rheumatic arthralgia, traumatic pain, etc. Aina sesame oil is a yellow oily liquid extracted from Aina incense. It contains a unique aroma. It has the functions of clearing away heat and detoxification, reducing swelling and pain, relieving itching, promoting blood circulation and dissipating blood stasis, etc. It is especially used to treat sore throat, m...
