Problems solved by technology

[0003] Yet people often only pay attention to the value of pitaya fruit, and ignore the application of the pitaya peel which is very rich in resources. Studies have found that there are relatively abundant flavonoids in the pitaya peel. Analyzing the content of flavonoids in the pitaya peel will help In the development and utilization of dragon fruit

Embodiment 1

[0087] This embodiment provides a composition that can significantly improve the body's immunity, and the composition includes the following components accounting for the weight percentage of the composition:

[0088] -95.00wt% dragon fruit extract; and

[0089] - 5.00 wt% Urtica schicycloid F,

[0090] Wherein, the dragon fruit extract is extracted through an aqueous solution of imidazole ionic liquid.

[0091] In the composition of the present invention, the dragon fruit extract can significantly improve the activity of lysozyme, albumin mass concentration, C3 mass concentration and superoxide dismutase in serum during immunization under the compatibility of nettle schicycloid F. (SOD) activity, the composition containing dragon fruit extract and nettle schicycloid F can promote the growth and development of immune organs to a certain extent, and significantly improve the immune function of the body.

[0092] In this preferred embodiment, the preparation method of the drag...

Embodiment 2

[0135] This preferred embodiment provides a kind of preparation method of the dragon fruit extract in the described composition, comprises the steps:

experiment example 1

[0174] A. Refer to the method of Yang Runya et al. (Yang Runya, Ming Yongfei, Wang Hui. Extraction of total flavonoids from fig leaves and determination of their antioxidant activity [J]. Food Science, 2010,31(16):78-82), rutin The concentration of the standard is 0.25mg / mL, using "NaNO 2 -Al(NO 3 ) 3 -NaOH" color development system and UV-Vis spectrophotometer measure rutin standard curve (there is maximum absorption peak at λ=510nm place), such as figure 2 Shown, the regression equation of rutin standard substance quality M and absorbance A is A=1.1665M-0.0062 (R 2 =0.999), it can be used for the quantitative determination of TFHF at 0.05-0.50 mg.

[0175] B. Use a pipette gun to pipette 2 mL of the dragon fruit extract test solution, add the reagents used in the color development system successively according to the method in the reference in A, shake well, and let it stand. The absorbance is substituted into the regression equation to obtain the corresponding total fl...

Abstract

The invention relates to a plant extract and application thereof, in particular to a composition containing a pitaya extract and application thereof. The composition comprises the pitaya extract and urtica fissas split-ring lignan F, wherein the pitaya extract is extracted by an imidazole ionic liquid aqueous solution. Particularly, a preparation method of the pitaya extract includes the steps that pitaya peel is provided; pitaya powder is obtained; an extraction technology is conducted, wherein the extraction technology includes the steps of mixing, extraction, refrigerated centrifugation, filter pressing and chromatographic separation; then, a fifth fraction is collected and concentrated to constant weight to obtain the pitaya extract. The pitaya extract in the composition is rich in pitaya general flavone; through compatibility of urtica fissas split-ring lignan F, the activity of lysozyme, the mass concentration of albumin, the mass concentration of C3 and the activity of superoxide dismutase in serum during immunization are significantly improved, growth and development of the immune organs can be promoted to a certain extent, and the human body immune functions are significantly improved.
