Embodiment Construction

[0017] Take 500Kg of dried turmeric produced in southern Shaanxi and soak it in 2500Kg of water for 24 hours, beat it with a beater, filter it with a 30-40 mesh screen, remove the coarse fiber residue, and obtain a slurry, and then filter the slurry with a coarse filter cloth to obtain a milky white filter. liquid and sediment. Precipitate the filtrate for 12-24 hours, press filter to obtain turmeric starch, wash with water, and dry to obtain 210Kg starch. The press-filtered aqueous solution is concentrated under reduced pressure to a specific gravity of 1.10-1.15, then precipitated with 95% ethanol until the alcohol content reaches 75-80%, and press-filtered to obtain pectin. The filtrate can produce alcohol. Hydrolyze the precipitate (2) filtered by coarse filter cloth with 500L hydrochloric acid solution of pH 1~2 for 2~4 hours, cool down to 20~30°C, extract 3 times with an equal volume of 6# solvent oil (or petroleum ether, gasoline), extract The solution was washed thre...

Abstract

The invention provides a green extraction technology for the comprehensive and efficient utilization of a Dioscorea zingiberensis resource. Saponins are extracted and simultaneously other effective components in Dioscorea zingiberensis, such as Dioscoreae starch, celluloses, a coronary heart disease control raw material, pectin, agricultural nucleic acids and the like, are comprehensively, efficiently and synchronously extracted through the technology. Rhamnose is extracted from a hydrolysis waste liquid; the whole process of the technology is green; and the technology has the advantages of great improvement of the saponin production level in China, improvement of the resource utilization efficiency, energy saving, environmental protection, realization of the unification of the economic benefit, the environmental benefit and the social benefit, and promotion of the sustainable development of Chinese economy and society.

Description

technical field [0001] The invention relates to a green extraction technology for comprehensive and efficient utilization of turmeric resources. Background technique [0002] Turmeric, also known as Chuandilong, Huotougen, native name Yabian Jiang, scientific name Dioscorea Zingiberensis C.H.Wright, is the rhizome of Dioscorea Zingiberensis C.H.Wright. The underground rhizome is a famous starchy plant and also a nourishing food , is a medicinal plant. It is mainly distributed in mountains, hills, and alpine mountainous areas with an altitude of more than 300 meters in Hubei, Sichuan, Shaanxi, Liao, Ji, and Hei. There are more than 50 species in my country, of which 17 species, 1 subspecies, and 2 variants contain saponin, accounting for more than 50% of the plants containing saponin in the world, and the content can reach up to 16.15%, exceeding the record of 15% of Dioscorea spicosa in Mexico. Ace species on . Its tubers have high medicinal and chemical value. After proce...
