Embodiment 1

[0030] Dried the wild sumac fruit and crushed it to below 10 mesh, weighed 100kg, added 400L of petroleum ether (boiling range: 30°C-60°C) and mixed for 45-50°C reflux extraction for 80min, filtered once with a ceramic membrane to obtain the filtrate, and then Concentrate under reduced pressure to dryness to obtain 45.6kg wild sumac crude wax. Add 70% ethanol and 300 L of ethanol aqueous solution of 0.0001 mol / L hydrochloric acid to the wild sumac filter residue, mix, reflux and extract at about 45°C for 50min, and filter once with a ceramic membrane to obtain the extract; 250L extract is concentrated at 50°C under reduced pressure to 30L, to obtain the concentrated solution I, on the AB-8 macroporous resin to absorb the concentrated solution, and to elute with 60% ethanol and 0.001mol / L ethanol aqueous solution of hydrochloric acid for four times the column volume, to obtain 60L eluent I, and Concentrate the eluent I at 50°C to 10L under reduced pressure to obtain concentrate...

Embodiment 2

[0032] Dried the wild sumac fruit and crushed it to below 10 mesh, weighed 200kg, added 600L of petroleum ether (boiling range: 30°C to 60°C) for mixing, refluxed at 50°C to 55°C for 60min, filtered once with a ceramic membrane to obtain the filtrate, and then Concentrate under reduced pressure to dryness to obtain 93.8kg wild sumac crude wax. Add 75% ethanol and 800L ethanol aqueous solution of 0.0001mol / L hydrochloric acid to the filter residue of Rhizoma chinensis, mix, reflux extraction at 50°C for 50min, and filter once with a ceramic membrane to obtain the extract; Concentrate the 700L extract to 80L at 50°C under reduced pressure , to obtain the concentrated solution I, the concentrated solution was absorbed on AB-8 macroporous resin, and eluted with 60% ethanol and 0.001mol / L ethanol aqueous solution of hydrochloric acid for three times the column volume to obtain 100L eluent I, and the eluted Deliquid I was concentrated under reduced pressure at 50°C to 15L to obtain ...

Abstract

The invention relates to a method for extracting rhoifolin and toxicodendron succedaneum wax from toxicodendron succedaneum. The method comprises the following steps: extracting dried toxicodendron succedaneum with petroleum ether; refluxing and extracting filter residues with a dilute acid alcohol solution; filtering, and concentrating to dry; dissolving with acid water; performing resin absorption, stepwise elution, concentration and crystallization to obtain purified products of rhoifolin and toxicodendron succedaneum wax. The method provided by the invention is simple in operation, greatly increases yield of rhoifolin and toxicodendron succedaneum wax, greatly reduces production costs of rhoifolin and toxicodendron succedaneum wax, simplifies production processes, and can also obtain large quantities of oily substances; the toxicodendron succedaneum is used as an extraction material to not only improve utilization efficiency of the toxicodendron succedaneum, but also increase an added value of the toxicodendron succedaneum.

Description

technical field [0001] The invention relates to a technology for extracting rhubaricin and barwax from wild sumac, and belongs to the technical field of natural product separation. Background technique [0002] Wild sumac wax is insoluble in water and cold ethanol; soluble in hot ethanol and organic solvents such as benzene, toluene, ether, petroleum ether, carbon disulfide, and vinyl chloride. In particular, it should be pointed out that wild sumac wax and many fatty and lipid components of cosmetics derived from animal and plant minerals, artificially compounded or chemically synthesized undergo thermal mutual fusion to form a homogeneous phase. The main composition of wild sumac wax is propaneol esters of saturated and unsaturated mixed fatty acids. Lacquer wax has a wide range of uses. Lacquer wax has the functions of food, medicine and health care. In some places in my country, there has been a habit of eating and medicinal use. It is used for cooking, frying food, mak...
