Problems solved by technology

However, due to the original extraction process (steam distillation) of woody volatile oil, it is difficult to extract, time-consuming and laborious, and the yield is low, and some heat-labile components are easy to decompose or oxidize, and the maximum effect of woody wood in Xianglian tablets cannot be maximized. , resulting in a waste of resources

Embodiment 1

[0021] The invention discloses a process for extracting volatile oil from Muxiang and the application of the volatile oil in the preparation of Xianglian Tablets, comprising the following steps:

[0022] (1) Get 1.2kg of woody incense with a water content of 12-14%, coarsely crush it into 6-8mm particles with a pulverizer, then store it in a stainless steel container, add 0.6kg of concentration and soak it in 75% ethanol, during Stir 3-5 times, let stand, seal and store for 24 hours.

[0023] (2) Squeeze and filter the woody fragrance soaked in the step (1) in an extruder with a pressing force of 80 tons to obtain a squeezed liquid and a filter cake. The filtered squeezed liquid is about 0.36 kg, and the obtained squeezed The liquid was left to stand for 4 hours, and the squeezed liquid was divided into upper and lower layers to obtain about 0.02 kg of the supernatant liquid and about 0.34 kg of the lower layer of turbid liquid for subsequent use.

[0024] (3) adding solvents...

Abstract

The invention provides a technology for extracting volatile oil in Radix Aucklandiae, and an application of the volatile oil in a Xianglian tablet. The technology comprises the following steps: taking Radix Aucklandiae, carrying out coarse crushing to form 6-8mm particles, storing in a stainless steel container, adding ethanol to immerse the particles, allowing the obtained mixture to stand, sealing, storing for 24h, and stirring during the storage period 3-5 times; and squeezing the immersed Radix Aucklandiae, filtering to obtain a squeezing liquid and a filter cake, allowing the squeezing liquid to stand for 4h in order to obtain a squeezing liquid upper layer and a squeezing liquid lower layer, and separating the squeezing liquid upper layer and the squeezing liquid lower layer for later use. The Xianglian tablet is prepared through wet granulation, the above lower turbid liquid is added during the granulation of the Xianglian tablet, and the above upper clear liquid is added during the granule straightening of the Xianglian tablet. The technology has the advantages of simple flow, easy control and operation, low production device requirements, and low production cost, can be well jointed to a product granulation technology, and effectively guarantees the product quality.

Description

technical field [0001] The present invention relates to the extraction of volatile oil from chrysanthemum, in particular to a process for extracting volatile oil from chrysanthemum and its application in xianglian tablets. Background technique [0002] Volatile oil, also known as essential oil, is a general term for a class of volatile oily components present in plants that have an aromatic odor, can be distilled with water vapor, and are immiscible with water. Volatile oil is a mixture with complex components. The essential oil is mainly produced by steam distillation and pressing. Terpenoids are the most common components of the volatile oil. In addition, it also contains small molecular aliphatic compounds and small molecular aromatic compounds. [0003] Muxiang was first recorded in "Shen Nong's Materia Medica", and it was listed as the top grade. It is the dried root of the Asteraceae plant in the family Asteraceae. It is widely used clinically, and it is mostly used f...
