One, the antioxidant activity test of Noni fruit essential oil
1. the measurement of scavenging ability of DPPH free radical
A certain amount of DPPH is weighed, the DPPH solution of 0.04mg/mL is configured to dehydrated alcohol.Take 2mL difference dense respectively
2mL DPPH solution is added in the solution of essential oil made from the Examples 1 to 2 of degree (2,4,6,8mg/mL), is uniformly mixed, room temperature is put
After setting 30min, 5000r/min is centrifuged 10min.Supernatant is taken to survey light absorption value at 517nm.Use Vc as positive control.Sample
The clearance rate of DPPH free radical is calculated with following formula:
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 that the DPPH clearance rate of Noni fruit essential oil is made in two methods is as shown in table 1:
Embodiment |
Embodiment 1 (distillation under vacuum) |
Embodiment 2 (atmospheric distillation) |
DPPH clearance rate (%) |
89.76 |
90.93 |
By table 1 the result shows that, distillation under vacuum of the invention and atmospheric distillation preparation essential oil all have preferably
DPPH free radical scavenging ability.
Two, ultraviolet light experiment is absorbed
The Whitening sunscreen cream containing Noni fruit essential oil and comparative example 1 of precise 0.06g Examples 1 to 6 respectively
Frost without Noni fruit essential oil is uniformly applied on the glass slide with medical adhesive tape, not smear the glass slide of suncream as sky
It is white, after timebase, the UV absorption average value of sample and reference substance in UVA, UVB, UVC wave band is scanned, it is more of the invention
The Whitening sunscreen cream containing Noni fruit essential oil and comparative example 1, blank control to ultraviolet radiation absorption situation.
Each embodiment and comparative example 1, blank control are shown in Table 2 to ultraviolet radiation absorption experimental result:

By table 2 the result shows that, Examples 1 to 6 be made the Whitening sunscreen cream containing Noni fruit essential oil to ultraviolet light inhale
Fruit of producing effects is good, has preferable sun-proof function.Wherein, embodiment 6 and embodiment 3 are preferable to ultraviolet radiation absorption effect, illustrate promise
When beautiful fruit essential oil weight part ratio is 1 part, Whitening sunscreen cream is best to ultraviolet radiation absorption effect.And comparative example 1 does not contain Noni fruit
The frost of essential oil is poor to ultraviolet radiation absorption.
Three, tyrosinase inhibitory activity measures
Tyrosinase is a kind of oxidoreducing enzyme, and tyrosinase oxidation can promote l-tyrosine to generate melanin, in junket
During propylhomoserin forms melanin, tyrosinase can promote l-tyrosine production L-3,4 dihydroxyphenylalanine and further act on to make L-3,4 dihydroxyphenylalanine shape
At a bar quinone, DOPA quinone ultimately generates melanin.
The calculation formula of inhibiting rate: [1- (T2-T1)/(C2-C1)] * 100%
C1 is the absorbance value of buffer solution and tyrosinase extracting solution, and C2 indicates the absorbance value of the melanin generated,
It is C2-C1 using the absorbance value that C1 surveys C2 as reference, indicates to generate after the absorbance for deducting tyrosinase extracting solution black
The absorbance value of pigment.T1 is the absorbance value that sample, tyrosinase extracting solution and buffer solution is added, and T2 is pressed down by sample
The absorbance value of the melanin generated after system, similarly obtains T2-T1 by the absorbance value that reference surveys T2 of T1, and expression is being deducted
Under the influence of sample and tyrosinase extracting solution absorbance, the absorbance value of the melanin after the inhibition of sample.Embodiment 1
Inhibiting rate result such as table 3 institute of the sample solution obtained to embodiment 6 and comparative example 1 in tyrosinase inhibitory activity measurement
Show:
Show the beauty containing Noni fruit essential oil that embodiment 1 is obtained to embodiment 6 by the test result of above-mentioned inhibiting rate
White suncream is strong to tyrosinase rejection ability, can be used for skin-whitening.Especially, the inhibiting rate highest of embodiment 6 is implemented
Example 3 is taken second place.When illustrating that Noni fruit essential oil weight part ratio is 1 part, Whitening sunscreen cream is to most strong to tyrosinase rejection ability.And it is real
The benefits of example 6 plays collaboration to tyrosinase inhibitory action compared to the component of embodiment more than 3 is applied, and comparative example 1 does not contain Noni fruit
The frost of essential oil inhibits poor to tyrosinase.Show that Noni fruit essential oil has preferable tyrosinase activity rejection ability, Nuo Li
There is fruit essential oil whitening sun protection effect can be used for preparing Whitening sunscreen cream.
Four, inhibit the animal model test of melanin growth
Zebra fish is a kind of in vitro fertilization, blastoprolepsis model animal, has been widely used in genetic development at present,
The multiple fields such as environmental monitoring.The model is also widely used for the influence that assessment compound grows melanin at present.Collect spot
Horse fish embryo is put into 96 orifice plates, 4 pieces of every hole embryo, and sample liquid prepared by embodiment 6 is added in 6hpf, and 72h observes zebra
Fish pigment growing state.Fig. 1 is sample liquid to zebrafish embryo pigment growth inhibition situation, and wherein A is normal zebrafish embryo,
B is influence of 6 sample liquid of embodiment to pigment.It is found from Fig. 1, the case where zebra fish normal relative to A, the pigment of B subtracts significantly
It is few, show that 6 sample liquid of embodiment inhibits the effect of melanin growth very good, illustrates the beauty of the invention containing Noni fruit essential oil
White suncream can inhibit melanin growth, play white-skinned face function.
In conclusion a kind of Whitening sunscreen cream containing Noni fruit essential oil of the invention, has significant DPPH free radical
Scavenging activity effectively inhibits the activity of tyrosinase, inhibits melanin growth, good to ultraviolet radiation absorption effect, realizes that whitening is anti-
Shine the effect of skin care.And the preparation method of Whitening sunscreen cream of the present invention is simple to operation, lower production costs, wherein benefit
Noni fruit essential oil is made with distillation under vacuum and atmospheric distillation, it is best in quality, there is preferable DPPH radical scavenging activity
Power, may be directly applied to skin care whitening, also can be applied to prepare other skin-lightening cosmetics or skin care item product.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the present invention.
