Embodiment 1

[0026] (1) Take the dried calyx calyx, crush it, pass through a 20-mesh sieve, place it in a round-bottomed flask, add 80% ethanol (V / W) at 8 times the concentration, reflux for 1 hour, and extract twice. The extract was filtered under reduced pressure, the filtrates were combined, and the solvent was recovered in a rotary evaporator until the ethanol was recovered completely to obtain a concentrated extract;

[0027] (2) Add 3 times the amount of distilled water (V / V) to the obtained extract concentrate, ultrasonically dissolve, centrifuge, and purify the supernatant with polyamide resin (100 mesh), and the loading ratio (V / W) is 3 : 1, repeated sample loading 4 times, each time the effluent was fully sampled, and stood for 1.5 hours; first eluted with distilled water for 2 column volumes, 2BV, and discarded; continued to elute 2BV with 35% ethanol by volume concentration, Discard; continue to elute 3BV with ethanol with a volume concentration of 55%, recover the solvent, and...

Embodiment 2

[0037] The method of this embodiment 2 is basically the same as that of embodiment 1, the difference is that the amount of ethanol added and the concentration of ethanol are different in step (1), and the flavonoid content and steroid content are measured respectively. The details are shown in Table 1 below.

[0038] Table 1

[0039] Amount of ethanol added (V / W) Ethanol concentration (%) Flavonoid content (mg / g) Steroid content (mg / g) 6 times the amount 80 5.6 3.2 7 times the amount 80 6.2 3.9 8 times the amount 80 7.0 4.3 9 times the amount 80 6.9 4.0 10 times the amount 80 6.4 3.7 8 times the amount 70 3.1 2.6 8 times the amount 90 6.9 4.6

[0040] It can be seen from the data in Table 1 that when the ratio of solid to liquid is 1:6 to 1:8, the content of flavonoids and steroids in the brocade lantern extract increases with the increase of ethanol addition, but the material The liquid ratio should no...

Embodiment 3

[0042] The method of this Example 3 is basically the same as that of Example 1, except that the amount of distilled water added and the sample loading ratio in step (2) are different, and the flavonoid content and steroid content are determined respectively. The details are shown in Table 2 below.

[0043] Table 2

[0044] Amount of distilled water added (V / W) Loading ratio Flavonoid content (mg / g) Steroid content (mg / g) 2 times the amount 3:1 4.7 2.8 3 times the amount 3:1 7.0 4.3 4 times the amount 3:1 5.3 3.6 3 times the amount 5:1 7.9 4.8 3 times the amount 7:1 6.8 3.9

[0045] It can be seen from the data in Table 2 that when the amount of distilled water added is 3 times that of the extract concentrate, the content of flavonoids and steroids in the brocade lantern extract is the highest. When the sample loading ratio was 5:1, the flavonoid and steroid content in the obtained Jindenglong extract was the highest....

Abstract

The invention discloses a multifunctional composite plant dye and a preparation method and application thereof. The preparation method comprises the steps that physalis alkekengi persistent calyx is used as a raw material, an ethanol reflux method is combined with a polyamide resin purification method to prepare physalis alkekengi steroids and flavone active components, physalis alkekengi fruits are used as a raw material, a solid dispersion medium is prepared through an ultrasonic water extraction method, the physalis alkekengi active component and the solid dispersion medium are made into a solid dispersion through a solvent evaporation method, a physalis alkekengi dye is obtained, cotton fabric is dyed in a direct dyeing mode, the dyed cotton fabric is bright in color and good in firmness, and the dyed fabric has good bacteriostatic activity on staphylococcus aureus and escherichia coli. According to the prepared physalis alkekengi natural dye, the physalis alkekengi persistent calyx and fruit resources are reasonably utilized, additional auxiliary materials do not need to be added, the prepared dye is green and environmentally friendly, no harmful substance is added in the whole preparation process, pollution to the environment is avoided, and the applicability of the dye is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of light chemical dyes and printing and dyeing, and in particular relates to a multifunctional composite plant dye and its preparation method and application. Background technique [0002] Brocade lantern is the dry persistent calyx or the persistent calyx with fruit of Physalis Physalis, a perennial herb of Solanaceae, which is a traditional Chinese medicine in my country. Jin Deng Lantern is rich in a variety of active ingredients, including steroids, flavonoids, phenylpropanoids and polysaccharides, which have significant antibacterial, anti-inflammatory, anti-oxidant and other pharmacological activities. For a long time, brocade lanterns have been mostly used as drugs in clinical practice, and other potential values ​​have not been fully developed. [0003] Historically, my country is an advanced country in dye plant application technology. Compared with other dyes, plant-derived dyes are not only green...
