Embodiment 1

[0019] The fresh Aina japonica leaves are crushed as extraction raw materials, weigh 500g, put into a supercritical extraction kettle and fully mix with glass beads. At extraction pressure 30MPa, temperature 20°C, CO 2 Flow 15L.h -1 1. Under the condition of time 15min, the translucent crystalline mugwort extract extracted from the fresh Aina japonica leaves was obtained. The purity of the extract is 57.69%, and the extraction rate is 63.34%.

Embodiment 2

[0021] It is basically the same as Example 1, except that the extraction pressure is 27MPa, the temperature is 30°C, the CO 2 Flow 20L.h -1 , The extract was obtained under the condition of time 20min. The purity of the extract is 59.31%, and the extraction rate is 64.62%.

Embodiment 3

[0023] It is basically the same as Example 1, except that the extraction pressure is 33MPa, the temperature is 35°C, the CO 2 Flow 15L.h -1 , The extract was obtained under the condition of time 25min. The purity of the extract is 64.01%, and the extraction rate is 68.45%.

Abstract

The invention discloses an extraction method of L-borneolum in blumea balsamifera leaves. The method comprises steps as follows: fresh blumea balsamifera leaves are crushed into an extraction material, the extraction material is put in a supercritical extraction kettle and sufficiently mixed with glass beads, extraction is performed at the temperature of 15-35 DEG C and under the CO2 fluid pressure of 25-35 MPa and the CO2 flow of 13-26 L.h<-1> for 15-30 min, an extract is cooled and crystalized, and coarse crystals of L-borneolum are obtained. Research prove that the product yield and purityare improved as compared those with existing process with the supercritical extraction method, and the method is good in repeatability, convenient and rapid to operate, high in safety, energy-saving,emission-reducing and applicable to industrial production.

Description

technical field [0001] The invention relates to a method for extracting traditional Chinese medicines, in particular to a high-efficiency preparation and separation technology for moxa tablets, in particular to a supercritical-based method for preparatively separating the moxa tablets from the leaves of Aina. Background technique [0002] Artemisia argyi is the crystallization made by extracting and processing the fresh leaves of Blumeabalsami era (L.) DC. Mainly distributed in southern China and Fujian, Taiwan, Guizhou, Yunnan and other places. Ai tablets have the effects of resuscitating the mind, clearing away heat and relieving pain. Commonly used for febrile coma, convulsions, apoplexy due to phlegm, qi depression, coma, red eyes, mouth sores, sore throat, and ear canal discharge. The main component of moxa tablets is L-borneol, which has antibacterial, anti-inflammatory, anti-thrombotic effects, and can also regulate the central nervous system and protect brain tissu...
