Embodiment 1

[0019] A method for extracting quercetin from psyllium, comprising the following steps:

[0020] (1) Coarsely crush fresh psyllium seeds and immerse in water for 25 minutes, then put them into a sieve basket and immerse the whole in liquid nitrogen for 50 minutes, then lift it up and place it at room temperature for 8 minutes, and then immerse the sieve basket in liquid nitrogen as a whole 50 minutes, so repeated 3 times;

[0021] (2) drying the psyllium in the step (1) at low temperature, pulverizing, and passing through a 20-mesh sieve to obtain the psyllium powder;

[0022] The low-temperature vacuum drying process is as follows: the psyllium seeds are stacked alternately in a vacuum drying oven, the vacuum degree is controlled to be 0.009Mpa, the vacuum drying temperature is 40°C, and the psyllium seeds are dried until the water content is below 5%;

[0023] (3) Fully mix the psyllium seed powder with 0.05 times the weight of β-glucosidase and let it stand for 50 minutes,...

Abstract

The invention discloses a method for extracting quercetin from semen plantaginis, and belongs to the technical field of quercetin extraction. The method comprises the following steps: (1) coarsely crushing fresh semen plantaginis, then putting the crushed semen plantaginis into a sieve basket, integrally immersing the sieve basket into liquid nitrogen, treating, and repeating the steps 2-3 times;(2) drying the semen plantaginis in the step (1) at low temperature, and crushing to obtain semen plantaginis powder; (3) extracting the semen plantaginis powder by adopting a supercritical CO2 extraction method; and (4) allowing CO2 containing the extract to flow out of the extraction kettle, allowing the CO2 to enter a separation kettle, and carrying out reduced pressure separation to obtain thesemen plantaginis quercetin. According to the method for extracting quercetin from semen plantaginis, the loss of quercetin in the extraction process of semen plantaginis is prevented from being considered, and the quality and the yield of quercetin extracted from semen plantaginis are improved.

Description

technical field [0001] The invention relates to a method for extracting quercetin in natural plants, in particular to a method for extracting quercetin in psyllium seeds. Background technique [0002] Plantago (scientific name: Plantago asiatica L.), also known as plantain, wheel grass, etc., biennial or perennial herb, [0003] Produced in many provinces of China. Born in grasslands, ditch, river bank wetlands, fields, roadsides or village open spaces, Plantain is the whole plant of Plantago and flat plantain, sweet in taste and cold in nature. It has the effects of expectorant, antitussive, and asthma. Plantain is a traditional Chinese medicine for promoting diuresis and expelling dampness. It mainly treats: dysuria, stranguria and leukorrhagia, edema and fullness, summer-dampness diarrhea, red eyes and cloudy eyes, phlegm-heat cough and dyspnea. Plantago leaves not only have significant diuretic effect, but also have obvious expectorant, antibacterial and antihypertens...
