Embodiment 1

[0022] Wash the persistent calyx physalis, dry at 50°C for 24 hours, pulverize with a pulverizer, and sieve with 100-200 mesh to obtain the persistent calyx physalis powder.

[0023] Fill the extraction kettle with the Physalis persistent calyx powder, and install the receiving device. Turn on the power and start the whole extraction device through the control system. The temperature of the refrigerator is set to about 5°C, and the temperature and pressure required for extraction are set by the control system. CO out of cylinder 2 , liquefied into a liquid by the refrigerator, pressurized by the pump to reach the required pressure, heated to the predetermined temperature by the preheater, and then enter the extraction kettle from the bottom for extraction. At this time, the CO in the supercritical state 2 Then the carotenoids are extracted from the persistent calyx of Physalis. CO dissolved in carotenoids 2 Enter the receiving separator through the pressure reducing valve,...

Embodiment 2

[0027] The experimental device and method were the same as in Example 1, wherein the extraction temperature was 60°C, the extraction pressure was 30 MPa, the particle size of the calyx physalis powder was 100-200 mesh, and the extraction time was 120 minutes. Through ultraviolet analysis, the extraction rate of this embodiment is about 11.32mg / g.

Embodiment 3

[0029] Experimental apparatus and method are identical with embodiment 1, supercritical CO 2 The extraction temperature is 50° C., the extraction pressure is 30 MPa, the extraction time is 120 minutes, and the particle size of the calyx physalis powder is 60-80 mesh. Through ultraviolet analysis, the extraction rate of this embodiment is about 9.20mg / g.

Abstract

The invention discloses a method for extracting carotenoid from physalis persistent calyx, aiming at providing a method for extracting carotenoid from physalis persistent calyx with the advantages of no requirement on organic solvents, short production cycle and high extraction ratio by adopting a supercritical CO2 extraction method. The method comprises the following steps of: washing, drying and crushing the physalis persistent calyx and sieving by a 20 to 200 mesh sieve; extracting the crushed and sieved physalis persistent calyx powder to obtain the carotenoid by adopting the supercritical CO2 extraction method, wherein the temperature of supercritical CO2 extraction is 35 to 65DEG C; the extraction pressure is 15 to 45MPa; and the extraction time is 30 to 200min. The method adopts the supercritical CO2 extraction method and has the advantages of friendly environment, no requirement on the organic solvents, simple and convenient extraction and separation process, no pollution, short production cycle and good quality of the prepared pigment, and the extraction ratio can reach 15.96mg/g by determining the process conditions of the temperature, the pressure, and the like in the extraction course.

Description

technical field [0001] The invention relates to an extraction method for extracting carotenoids with anticancer effect from the persistent calyx of Physalis physalis, a medicinal and edible plant rich in carotenoids. Background technique [0002] Physalis is a perennial herb of the Solanaceae Physalis genus, also known as red girl, hanging golden lantern, lantern grass, roselle pearl, bubble grass, etc. Our country is rich in wild resources, which are distributed in all places except Tibet, mostly in the north. Its enlarged persistent calyx can be used as medicine, which has the effects of cooling, reducing phlegm, antitussive and diuretic. (Hui Bodi, Wang Yajing, Pei Lingpeng, etc., analysis of carotenoid composition in Physalis berry and persistent calyx, Chinese Journal of Pharmaceutical Sciences, 2006, 41, 583-584.) research shows that Physalis persistent calyx is rich in Carotenoids, the main components of which are zeaxanthin and lutein. At the same time, many schol...
