Embodiment 1

[0022] (1) Concentration of gardenia yellow pigment waste liquid: using the waste liquid with a geniposide content of 10% after water extraction and membrane separation and purification of gardenia yellow pigment as raw material, the reverse osmosis membrane is used to degrade the waste gardenia yellow pigment. The liquid is concentrated, the concentration temperature is controlled at 40°C, the concentration pressure is controlled at 2.0Mpa, and concentrated to a relative density of 1.0 to obtain the gardenia yellow pigment waste liquid concentrate;

[0023] (2) Extraction of geniposide: Add isobutanol to the obtained concentrated gardenia yellow pigment waste liquid and stir evenly for 2 extractions, combine the extracts, and adjust the pH value to 8 while adding isobutanol for each extraction , stand still for 30 minutes for each extraction, and the volume of isobutanol added for each extraction is 1 times the volume of the gardenia yellow pigment waste liquid concentrate;

Embodiment 2

[0037] (1) Concentration of gardenia yellow pigment waste liquid: using the waste liquid with 1% geniposide content after water leaching and purification of gardenia yellow pigment by membrane separation as raw material, using reverse osmosis membrane to treat gardenia yellow pigment waste The liquid is concentrated, the concentration temperature is controlled at 45°C, the concentration pressure is controlled at 2.5Mpa, and concentrated to a relative density of 1.10 to obtain a concentrated solution of gardenia yellow pigment waste liquid;

[0038] (2) Extraction of geniposide: add isobutanol to the obtained gardenia yellow pigment waste concentrate and stir evenly for 3 extractions, combine the extracts, and adjust the pH value to 10 while adding isobutanol for each extraction , leave standstill for 45 minutes for each extraction, and the volume of adding isobutanol for each extraction is 3 times of the volume of the concentrated liquid of gardenia yellow pigment waste liquid;...

Embodiment 3

[0052] (1) Concentration of gardenia yellow pigment waste liquid: using the waste liquid with 12% geniposide content after water extraction and membrane separation and purification of gardenia yellow pigment as raw material, reverse osmosis membrane is used to treat gardenia yellow pigment waste The liquid is concentrated, the concentration temperature is controlled at 50°C, the concentration pressure is controlled at 3.0Mpa, and concentrated to a relative density of 1.20 to obtain a concentrated solution of gardenia yellow pigment waste liquid;

[0053](2) Extraction of geniposide: add the obtained concentrated gardenia yellow pigment waste liquid into isobutanol and stir evenly for 4 extractions, combine the extracts, and adjust the pH value to 12 while adding isobutanol for each extraction. , standing for 60 minutes for each extraction, and the volume of isobutanol added for each extraction is 5 times the volume of the gardenia yellow pigment waste liquid concentrate;

Abstract

The invention discloses a method for extracting geniposide from gardenia yellow pigment waste liquor, which mainly comprises the following steps: concentrating gardenia yellow pigment waste liquor used as a raw material through a reverse osmosis membrane, extracting with isobutanol, decolorizing with active carbon, concentrating, performing crystallization purification twice, and finally drying. The invention can solve the waste problem that the gardenia effective component can not be economically and effectively recovered from the gardenia yellow pigment producing waste liquor in an environment-friendly way.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine waste liquid treatment, in particular to a method for extracting geniposide from gardenia yellow pigment waste liquid. Background technique [0002] Gardenia is also known as yellow gardenia, mountain gardenia, and white toad, and it is the fruit of the Rubiaceae plant gardenia. At present, the fruit of gardenia is a traditional Chinese medicine, which belongs to the first batch of medicinal and edible resources promulgated by the Ministry of Health. It has the functions of protecting the liver, promoting gallbladder, lowering blood pressure, calming, stopping bleeding, and reducing swelling. It is often used in the treatment of jaundice in Chinese medicine clinics Hepatitis, sprains, high blood pressure, diabetes, etc. The active ingredients of gardenia mainly include iridoids such as gardenia yellow pigment and geniposide. Among them, geniposide has multiple uses. After fe...
