Abstract

The invention provides a deep eutectic solvent which is composed of lactic acid, D-(+)-glucose and water, wherein the mole ratio of the lactic acid to the D-(+)-glucose in the deep eutectic solvent is (1-2):(1-5), and the water content is 0-80% (V/V). The invention also provides application of the deep eutectic solvent and a method for extracting anthraquinone from radix et rhizoma rhei by using the deep eutectic solvent. When being used for extracting anthraquinone from radix et rhizoma rhei, the deep eutectic solvent replaces chloroform and other toxic organic solvents in the traditional extraction, reduces the environmental pollution of the radix et rhizoma rhei industry, and thus, is green and environmentally friendly. The deep eutectic solvent has high extraction efficiency and is recyclable and reusable, thereby greatly lowering the extraction cost, and providing a new technical means for reasonable development and utilization of radix et rhizoma rhei resources.

Description

technical field [0001] The invention provides a deep eutectic solvent and a method for extracting anthraquinone in rhubarb, belonging to the field of comprehensive utilization of Chinese medicinal material resources. Background technique [0002] Rhubarb is a herbal medicine included in the Pharmacopoeia of the People's Republic of China (2015 Edition, Part One), and its medicinal sources are Rheum palmatum L., Rheumtanguticum Maxim.exBalf. or Rheum officinaleBaill The dried roots and rhizomes of . Bitter in taste, cold in nature, it returns to the spleen, stomach, liver, large intestine, and heart meridian. It has the functions of purging stagnation, clearing away heat and fire, cooling blood and detoxifying, removing blood stasis and dredging menstrual flow. The main active ingredients are rhein, emodin, and chrysophanol , emodin methyl ether, aloe-emodin, etc. Modern pharmacological studies have shown that rhubarb has the functions of purging, antibacterial, anti-tumor,...
