A kind of Whitening sunscreen cream containing Noni fruit quintessence oil and preparation method thereof
Technical field
The present invention relates to Noni fruit and be applied to cosmetic field, particularly relate to a kind of whitening sun protection containing Noni fruit quintessence oil
Frost and preparation method thereof.
Background technology
Noni is Rubiaceae Morinda plant, has another name called Morinda Citifolia, Solanum pseudo-capsicumvar diflorum (Vell.)Bitter, India's Fructus Mori, and this plant is the most coastwise
In being grown on the bushes at seabeach, and wetland is taken up in the seashore of many stone, roadside, streams, is mainly distributed on the South Sea Islands
Small island, such as Philippine, Australia, Cambodia etc..Also there are substantial amounts of plantation, conservative estimation cultivated area in existing China Hainan, Taiwan
10000 mu of Hainan, 4000 mu of Yunnan.Noni contains 60 multiple nutritional components, including vitamin, trace element, flavone, phenylpropyl alcohol
Element, polysaccharide etc., have stronger functional characteristic, and root, stem, leaf, flower, fruit all can be used as medicine.Root can obtain the dyestuff of yellow or redness
For contaminating clothes, edible fruit use, as food and health product.Noni is used as food by the Polynesian on island, the South Pacific Ocean
Product, medicine there are about history in 2000.Noni can suppress and cure multiple disease.Such as arthritis, diabetes, hypertension, muscle
Pain, menoxenia, headache, heart disease, acquired immune deficiency syndrome (AIDS), tumor, digestive tract ulcer, various sprain, depression, aging, dyspepsia,
Arteriosclerosis, blood vessel aspect problem and be addicted to drug.Phenylpropanoids can suppress tryrosinase according to the literature

One, the antioxidant activity test of Noni fruit quintessence oil
1. the mensuration of scavenging ability of DPPH free radical
Weigh a certain amount of DPPH, be configured to the DPPH solution of 0.04mg/mL with dehydrated alcohol.Take 2mL difference respectively dense
Quintessence oil that the embodiment 1~2 of degree prepares (2,4,6,8mg/mL) solution, add 2mL DPPH solution, mix homogeneously, room temperature is put
After putting 30min, 5000r/min is centrifuged 10min.Take supernatant at 517nm, survey light absorption value.With Vc as positive control.Sample
The clearance rate below equation of DPPH free radical is calculated:
A0: the light absorption value of 2mL dehydrated alcohol+2mL DPPH solution;
A1: the light absorption value of 2mL sample solution+2mL DPPH solution;
A2: the light absorption value of 2mL sample solution+2mL dehydrated alcohol;
The test result of the DPPH clearance rate that two kinds of methods prepare Noni fruit quintessence oil is as shown in table 1:

Being shown by the result of table 2, ultraviolet is inhaled by the Whitening sunscreen cream that embodiment 1~6 prepares containing Noni fruit quintessence oil
Receive effective, possess preferable sun-proof function.Wherein, embodiment 6 and embodiment 3 are preferable to ultra-violet absorption effect, and promise is described
When beautiful fruit quintessence oil weight part ratio is 1 part, Whitening sunscreen cream is to ultra-violet absorption best results.And comparative example 1 does not contains Noni fruit
The frost of quintessence oil is poor to ultra-violet absorption.
Three, tyrosinase inhibitory activity measures
Tryrosinase is a kind of oxidoreductase, and tryrosinase oxidation can promote that TYR generates melanin, at cheese
Propylhomoserin formed melanic during, tryrosinase can promote TYR produce L-3,4 dihydroxyphenylalanine and further effect make L-3,4 dihydroxyphenylalanine shape
Becoming bar quinone, DOPA quinone ultimately generates melanin.
The computing formula of suppression ratio: [1-(T2-T1)/(C2-C1)] * 100%
C1 is buffer solution and the absorbance of tryrosinase extracting solution, and C2 represents the melanic absorbance of generation,
Being C2-C1 with the absorbance that C1 surveys C2 for reference, it is black that expression generates after the absorbance of deduction tryrosinase extracting solution
The absorbance of pigment.T1 is to add sample, tryrosinase extracting solution and the absorbance of buffer solution, and T2 is to press down through sample
The melanic absorbance generated after system, same obtains T2-T1 with the absorbance that T1 is reference survey T2, represents and deducting
Under the influence of sample and tryrosinase extracting solution absorbance, the melanic absorbance after the suppression of sample.Embodiment 1
The sample solution obtained to embodiment 6 and comparative example 1 suppression ratio result such as table 3 institute in tyrosinase inhibitory activity measures
Show:
Shown by the test result of above-mentioned suppression ratio, U.S. containing Noni fruit quintessence oil that embodiment 1 to embodiment 6 obtains
White sunscreen cream is strong to tryrosinase rejection ability, may be used for skin-whitening.Especially, the suppression ratio of embodiment 6 is the highest, implements
Example 3 is taken second place.Illustrate that, when Noni fruit quintessence oil weight part ratio is 1 part, Whitening sunscreen cream is to the strongest to tryrosinase rejection ability.And it is real
Execute example 6 to compare the component of embodiment more than 3 tyrosinase inhibitory action plays collaborative effect, and comparative example 1 does not contains Noni fruit
The frost of quintessence oil is poor to tryrosinase suppression.Show that Noni fruit quintessence oil has preferable tyrosinase activity rejection ability, noni
Really quintessence oil has whitening sun protection effect and may be used for preparing Whitening sunscreen cream.
Four, the animal model test of suppression melanin growth
Brachydanio rerio is the model animal of a kind of external fertilization, blastoprolepsis, has been widely used in genetic development,
Multiple field such as environmental monitoring.This model is also widely used for assessing the impact that melanin is grown by compound at present.Collect speckle
Horse fish embryo puts in 96 orifice plates, 4 pieces of every hole embryo, adds the sample liquid of embodiment 6 preparation when 6hpf, and 72h observes zebra
Fish pigment growing state.Fig. 1 be sample liquid to zebrafish embryo pigment growth inhibited situation, wherein A is normal zebrafish embryo,
B is the impact on pigment of embodiment 6 sample liquid.Finding from Fig. 1, relative to the situation of the normal Brachydanio rerio of A, the pigment of B subtracts significantly
Few, show that the effect of embodiment 6 sample liquid suppression melanin growth is the best, U.S. containing Noni fruit quintessence oil of the present invention is described
White sunscreen cream can suppress melanin to grow, and plays white-skinned face function.
In sum, a kind of Whitening sunscreen cream containing Noni fruit quintessence oil of the present invention, there is significant DPPH free radical
Scavenging activity, effectively suppresses the activity of tryrosinase, and suppression melanin grows, effective to ultra-violet absorption, it is achieved whitening is prevented
Shine the effect of skin protection.And the preparation method of Whitening sunscreen cream of the present invention is simple to operation, production cost is relatively low, Qi Zhongli
Preparing Noni fruit quintessence oil with distillation under vacuum and atmospheric distillation, it is best in quality, has preferable DPPH radical scavenging activity
Power, may be directly applied to skin protection whitening, it is also possible to be applied to prepare other skin-lightening cosmetics or skin care item product.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. done, within should be included in the scope of protection of the invention.
