Embodiment 1

[0019] A method for extracting, separating and purifying moxa tablets of the present invention adopts the following process steps:

[0020] 1. Simultaneous distillation and extraction: crush the leaves and twigs of Ainaxiang powder into Ainaxiang powder, with a particle size of 0.1-1mm. Add 50g of the pulverized Ainaxiang powder into 1L of water, heat to a slight boil to generate water vapor , while heating 100mL of petroleum ether (boiling range 30-60°C) to slightly boil to produce petroleum ether vapor, when the two-phase steam meets, the petroleum ether vapor extracts the fat-soluble volatile components carried by the water vapor, and the two are condensed in the condenser at the same time, due to the water The incompatibility with petroleum ether separates the two, wherein the distilled water phase is refluxed into the water bottle, and the petroleum ether phase is refluxed into the petroleum ether bottle. The whole process takes 5 hours to obtain the Ainaxiang petroleum et...

Embodiment 2

[0025] A method for extracting, separating and purifying moxa tablets of the present invention adopts the following process steps:

[0026] 1. Simultaneous distillation and extraction: crush the leaves and twigs of Ainaxiang powder into Ainaxiang powder with a particle size of 0.1-1mm, add 5kg of crushed Ainaxiang powder into 5L of water, and heat to a slight boil to generate water vapor , while heating 1L of petroleum ether (boiling range 30-60°C) to slightly boil to generate petroleum ether vapor. When the two-phase steam meets, the petroleum ether vapor extracts the fat-soluble volatile components carried by the water vapor, and the two are condensed in the condenser at the same time. The incompatibility with petroleum ether separates the two, wherein the distilled water phase is refluxed into the water bottle, and the petroleum ether phase is refluxed into the petroleum ether bottle. The whole process takes 10 hours to obtain the Ainaxiang petroleum ether extract;

[0030] A method for extracting, separating and purifying moxa tablets of the present invention adopts the following process steps:

[0031] 1. Simultaneous distillation and extraction: crush the leaves and twigs of Ainaxiang powder into Ainaxiang powder, with a particle size of 0.1-1mm. Add 10kg of the pulverized Ainaxiang powder into 10L of water, heat to a slight boil to generate water vapor , while heating 1L of petroleum ether (boiling range 30-60°C) to slightly boil to generate petroleum ether vapor. When the two-phase steam meets, the petroleum ether vapor extracts the fat-soluble volatile components carried by the water vapor, and the two are condensed in the condenser at the same time.

Abstract

The invention relates to a method for extraction and separation purification of blumea balsamifera (L.)DC. sheets and belongs to the technical field of extraction and deep processing of plants. The method provided by the invention is characterized in that raw materials of blumea balsamifera (L.)DC. leaves and twigs are crushed and then are subjected to simultaneous distillation extraction, reduced pressure evaporation and reduced pressure sublimation separation purification to produce the blumea balsamifera (L.)DC. sheets. The blumea balsamifera (L.)DC. sheets obtained by the method satisfy quality requirements of the ''Chinese pharmacopoeia'' standard. The method provided by the invention has a blumea balsamifera (L.)DC. sheet extraction rate of 90%, a recovery rate of 80%, simple extraction and separation purification processes, high efficiency and a large treatment capacity, is suitable for industrial production, provides a technical support for extraction and separation purification of the blumea balsamifera (L.)DC. sheets, and provides natural superior raw materials for industries of medicines, medical cosmetology and essence.

Description

technical field [0001] The invention relates to a method for extracting, separating and purifying moxa slices, and in particular belongs to the technical field of plant extraction and deep processing. Background technique [0002] Ai Pian, also known as Ai Nao, L-borneol or L-borneol, is a kind of borneol. "Chinese Pharmacopoeia 2010" divides borneol into three categories, namely, Ai tablet, natural borneol and synthetic borneol. Ai Pian is extracted from the leaves and twigs of Blumea balsamifera (L.) DC., a plant of the genus Ai Na Xiang (Blumea balsamifera (L.) DC.). Convulsion, stroke, phlegm, qi depression, coma, red eyes, mouth sores, sore throat, and ear canal discharge are important components of various Chinese patent medicines and ethnic medicines (Miao medicine). The main component of moxa tablet is L-borneol, and the chemical name of L-borneol is L-2-borneol or L-endotype-1,7,7-trimethylbicyclo[2.2.1]hept- 2-alcohol, molecular formula C 10 h 17 OH, the struct...
