The specific embodiment
Below by embodiment, also by reference to the accompanying drawings the present invention is further set forth, but do not limit the present invention.
embodiment 1
A Hibiscus Sabdariffa Linn extract, by the following method preparation:
(1), add in deionized water Hibiscus Sabdariffa Linn is dry, control the mass ratio calculating of Hibiscus Sabdariffa Linn and deionized water, i.e. Hibiscus Sabdariffa Linn: deionized water is to obtain mixed liquor after 1:10 mixes;
It is 25 ℃ that the mixed liquor of gained is controlled temperature, and power is 150W, carries out after supersound extraction 15-30min, with 0.45 μ m filtering with microporous membrane under the ultrasound condition that frequency is 40kHz;
(2), step (1) is filtered under the condition that rear resulting filtrate control vacuum is 0.094-0.096MPa and carry out rotary evaporation in vacuo, obtain Hibiscus Sabdariffa Linn extract concentrated solution, it is-55 ℃ of lyophilizations that the Hibiscus Sabdariffa Linn extract concentrated solution of gained is controlled to temperature, obtains Hibiscus Sabdariffa Linn extract.
The Hibiscus Sabdariffa Linn extract of above-mentioned gained is carried out to inhibition the effects to tryrosinase respectively, and its concrete steps are as follows:
(1), the extraction of tryrosinase:
Diced after potato decortication, put into refrigerator-20 ℃ freezing 24h, get 10g left and right and put into beater, add 30mL phosphate buffer solution to pull an oar, then pour in beaker, be placed on refrigerator interior standing, require refrigerator temperature to be set in 0-5 ℃;
(2), OD
1the test of value:

Test parallel three times, averaged, calculates now Hibiscus Sabdariffa Linn extract to tyrosinase inhibition rate, the computing formula of suppression ratio rate: suppression ratio (%)=[1-(OD
1-OD
3)/(OD
2-OD
4)] * 100%;
Hibiscus Sabdariffa Linn extract is shown in curve corresponding to extract in Fig. 1 to tyrosinase inhibition rate curve, from the curve that the extract of Fig. 1 is corresponding, can find out, Hibiscus Sabdariffa Linn extract 23.8% when 12.5% during from 1min is increased to 6min gradually to the suppression ratio of tyrosinase inhibition rate, and this value is on a declining curve after 10min, show that thus Hibiscus Sabdariffa Linn extract has good tryrosinase and suppresses ability, but the inhibition time falls short of, this may be lower the causing of effective ingredient concentration in Hibiscus Sabdariffa Linn extract.
In sum, can show that Hibiscus Sabdariffa Linn extract has certain inhibition ability to tryrosinase, show that thus Hibiscus Sabdariffa Linn extract is a kind of safe and effective natural plant whitening composition, therefore can be used as whitening and skin-protecting agent for skin-lightening cosmetic.
comparative example 1
With one of tyrosinase inhibitor conventional in prior art vitamin C, compare, with vitamin C concentration (10mg/mL), replace Hibiscus Sabdariffa Linn extract under the same conditions, carry out suppression ratio the effects.
It the results are shown in Figure curve corresponding to Vc in 1, the curve that Vc is corresponding from Fig. 1 can be found out, during 2min, vitamin C is 17.5% to the suppression ratio of tryrosinase, then be increased to gradually 35% after 18min, shown that thus vitamin C has good whitening ability as conventional tyrosinase inhibitor.
In sum, can draw under the same conditions, in the scope of 0-4min, the tyrosinase inhibition rate of the Hibiscus Sabdariffa Linn extract solution of 10mg/mL increases gradually, and suitable to solution suppression ratio with the vitamin C of 10mg/mL, after 10min, vitamin C continues to increase to suppression ratio, Hibiscus Sabdariffa Linn extract suppression ratio declines, illustrate that Hibiscus Sabdariffa Linn extract has certain whitening ability, and its effect and vitamin C are suitable in 2-9min time range, again having confirmed above-mentioned Hibiscus Sabdariffa Linn extract is a kind of safety, effective natural plant whitening composition, can be used as whitening and skin-protecting agent for skin-lightening cosmetic.

(2), by 30g solid grease, be that the acid of 11.25g stearic acid, 11.25g myristic acid, 3.75g Palmic acid and 3.75g lauric acid, 1g emulsifying agent are that 0.5g monoglyceride and 0.5g ceteareth-20 are mixed and heated to 75 ℃ and stir and dissolve, obtain oil phase;
(3), first oil phase is put into emulsifying pot, opened and stir, water is joined to oil phase fast, control mixing speed is 10000-20000rpm/min;
(4), after water added, 80-90 ℃ of hierarchy of control temperature carried out saponification 30-60min;
(5), after finishing, to add 15g surfactant be 7.5g lauroyl N-methyltaurine sodium and 7.5g monoalkyl phosphoric acid esters in saponification; the Hibiscus Sabdariffa Linn extract, the 0.1g chelating agen EDETATE SODIUM that while being cooled to 50-60 ℃, add 0.1g antiseptic 0.67g hydroxyphenyl methyl ester and 0.33g hydroxyphenyl propyl ester, 0.02g embodiment 1 gained; be cooled to again 40-45 ℃ cream can be tied to system time; keep 40-45 ℃; controlling mixing speed is that 100-500rpm/min stirs 30-60min, after stirring finishes, both must contain the cleansing milk of Hibiscus Sabdariffa Linn extract.
embodiment 2
A Hibiscus Sabdariffa Linn extract, by the following method preparation:
(1), add in ethyl acetate solvent Hibiscus Sabdariffa Linn is dry, control the mass ratio calculating of Hibiscus Sabdariffa Linn and ethyl acetate solvent, i.e. Hibiscus Sabdariffa Linn: ethyl acetate solvent is to obtain mixed liquor after 1:10 mixes;
It is 25 ℃ that the mixed liquor of gained is controlled temperature, and power is 150W, carries out after supersound extraction 20min, with 0.45 μ m filtering with microporous membrane under the ultrasound condition that frequency is 40kHz;
(2), step (1) is filtered under the condition that rear resulting filtrate control vacuum is 0.094 ~ 0.096MPa and carry out rotary evaporation in vacuo, obtain Hibiscus Sabdariffa Linn extract concentrated solution, it is-55 ℃ of lyophilizations that the Hibiscus Sabdariffa Linn extract concentrated solution of gained is controlled to temperature, obtains Hibiscus Sabdariffa Linn extract.
Foregoing is only the basic explanation of the present invention under conceiving, and according to any equivalent transformation that technical scheme of the present invention is done, all should belong to protection scope of the present invention.
