Problems solved by technology

The existing mature technology for extracting flavonoids in Shui Luo umbrella is mainly solvent extraction method. The disadvantage of this method is that the content of total flavonoids in extracting Shui Luo umbrella is only 1.24-2.24%. Large dosage, cumbersome operation, difficult to control
with supercritical CO 2 Fluid extraction and reflux extraction techniques have not been reported so far for the extraction of total flavonoids from Shuiluo umbrella

Embodiment 1

[0025] (1) Wash the fresh roots of Shuiluosan, cut into slices, dry below 60°C, grind them with a universal grinder (without sieve) and set aside.

[0026] (2) Take 200g of dried medicinal material coarse powder and put it into a 1L extraction kettle, heat the extraction kettle to 40°C, and desorption kettles I and II through a heat exchanger to reach 40°C. The storage tank is cooled by refrigeration equipment, and the CO is turned on 2 Steel cylinder (flow rate is 25L / h), open booster pump and raise the pressure of extraction kettle to 30MPa, the pressure of analysis kettle I and II to 6.0MPa, close CO 2 Cylinder valve. Open the cycle, add ethanol carrier (30% of the amount of medicinal material) to the carrier storage tank, open the valve of the carrier high-pressure pump, pump the carrier into the extraction kettle, keep constant pressure and temperature, and extract for 3 hours.

[0027] (3) Collect the extract discharged from the outlets of the analysis kettle I and II....

Embodiment 2

[0030] (1) Wash the fresh roots of Shuiluosan, cut into slices, dry below 60°C, grind them with a universal grinder (without sieve) and set aside.

[0031] (2) Take 200g of dried medicinal material coarse powder and put it into a 1L extraction kettle, heat the extraction kettle to 35°C, and desorption kettles I and II to reach 35°C through a heat exchanger. The storage tank is cooled by refrigeration equipment, and the CO is turned on 2 Steel cylinder (flow rate is 32L / h), open booster pump and raise the pressure of extraction kettle to 30MPa, the pressure of analysis kettle I and II to 6.2MPa, close CO 2 Cylinder valve. Open the cycle, add ethanol carrier (30% of the amount of medicinal material) to the carrier storage tank, open the valve of the carrier high-pressure pump, pump the carrier into the extraction kettle, keep constant pressure and temperature, and extract for 5 hours.

Embodiment 3

[0035] (1) Wash the fresh roots of Shuiluosan, cut into slices, dry below 60°C, grind them with a universal grinder (without sieve) and set aside.

[0036] (2) Take 200g of dried medicinal material coarse powder and put it into a 1L extraction kettle, heat the extraction kettle to 35°C, and desorption kettles I and II to reach 40°C through a heat exchanger. The storage tank is cooled by refrigeration equipment, and the CO is turned on 2 Steel cylinder (flow rate is 32L / h), open booster pump and raise the pressure of extraction kettle to 35MPa, the pressure of analysis kettle I and II to 6.1MPa, close CO 2 Cylinder valve. Open the cycle, add ethanol carrier (30% of the amount of medicinal material) to the carrier storage tank, open the valve of the carrier high-pressure pump, pump the carrier into the extraction kettle, keep constant pressure and temperature, and extract for 5 hours.

Abstract

The invention discloses an extracting method of caulifora hemsl total flavone, which can be used for enhancing extraction rate and content of total flavone in caulifora hemsl. The invention employs extracting method of supercritical carbon dioxide fluid and uses ethanol as cosolvent. Extraction which contains caulifora hemsl flavone compound can be extracted from medicinal material caulifora hemsland caulifora hemsl total flavone can be extracted from the extraction by refluxing and extracting method.

Description

technical field [0001] The invention relates to a method for extracting effective components of plants, more specifically to a method for extracting total flavonoids in the plant Shuiluo umbrella. Background technique [0002] The dry root or stem of Fordia cauliflora Hemsl., also known as shrimp silk bean, soil licorice, and wild Jingdou, is a commonly used medicinal material in Guangxi. Sweet, slightly pungent, flat in nature, non-toxic, has the effects of dispelling blood stasis, reducing swelling, relieving pain and calming the mind, and improving intelligence. Indications for bruises, swelling and pain, kidney deficiency, low back pain, migraine, infantile malnutrition, mental retardation, fractures, post-illness and postpartum weakness. Shuiluo umbrella is a unique plant species in my country, mainly produced in Guangxi and Guangdong. Fujian, Hainan, and Yunnan are also distributed. This product is very rich in natural resources in Guangxi, and has been used in Zhua...
