Embodiment

It is the preparation embodiment and effete test embodiment at daffodil chloroform recovery position of the present invention below, to the technology of the present invention Scheme and technique effect are described further and explained.However, embodiments of the invention are only used for explaining the present invention, without It is limitation of the present invention, application claims is belonged to the simple modifications of following preparation method under the concept thereof of the present invention The scope of protection.

The preparation at the daffodil chloroform recovery position of embodiment 1

The drying petal 1.16kg of daffodil is taken, after being 95% alcohol solution dipping 24h with 12L volume parts, is heated back Stream extraction 3 times, each extraction time is 2h, merges extract solution, is filtered, and is condensed into medicinal extract after the recovered ethanol of filtrate, adds 800mL Water is dissolved, and equal-volume extraction is carried out repeatedly to extracting liquid colourless with chloroform, drying, powder after the recovered solvent of gained chloroform extract The broken mesh sieve of mistake 100, obtain daffodil chloroform recovery position dry powder.

The preparation of the narcissus flower extract face cream of embodiment 2

(1) Miglyol 812 70g, stearic acid 50g, dimethyl siloxane 50g, isopropyl palmitate 40g are weighed, it is single Sweet fat 10g and methyl hydroxybenzoate 1g, mixing, are heated to 80 DEG C, fusing stirs, as oil phase；

(2) 600ml deionized waters are measured, add 1,2-PD 80ml and triethanolamine 10ml,

Stirring makes mixing, and daffodil chloroform recovery position dry powder 3.5g prepared by embodiment 1 is added in mixed solution, is heated to 85 DEG C, stirring and dissolving is uniform, as aqueous phase；

(3) oil phase and aqueous phase are added in emulsification pot, stirred, emulsifying homogeneous 6min, when stirring is cooled to 50 DEG C, added Enter 1g essence, stir, be cooled to 38 DEG C, as narcissus flower extract face cream.By the narcissus flower extract in aqueous phase with Deionized water replaces, and blank control face cream sample is made in the same manner.

The skin-whitening performance test experiment of the narcissus flower extract face cream of embodiment 3

It is recipient site to select the volunteer of 10 skin healths or so inner forearm 3cm × 3cm regions, and side is smeared real The testing sample of the preparation of example 2 is applied, opposite side smears blank control sample.Early daily, evening respectively uses 1 time, totally 4 weeks, is kept away after smearing Exempt to be washed with water.The dermal melanin tester inspection produced respectively before use and after 1 week with German CK electronics corporations Melanin content in skin.Dermal melanin rate of change is calculated as follows：Measured after melanin rate of change=smearing sample Dermal melanin content × 100% measured before dermal melanin content/smearing sample.

The color of skin depends primarily on the content of melanin in human body skin, passes through the content detection energy to skin pigment Reflect the whitening effect of skin aging degree and cosmetics.Fig. 1 is using after narcissus flower extract face cream and control face cream The situation of change of human body skin melanin.As shown in Figure 1, with the extension of usage time, the tested area of blank control face cream Domain melanin content is without significant changes, and for melanin content than having a small amount of reductions before smearing, this is due to human body itself metabolism And caused by environmental factor.And smear tested region melanin content the prolonging with usage time of narcissus flower extract face cream Grow and gradually decrease, this is due to that narcissus flower extract has the content for reducing lipid peroxidation product MDA, improves skin The effect of middle SOD activity.Therefore, appropriate daffodil chloroform extract extract is added in cream formula, and can to reduce skin black Pigment content, there is whitening effect.

The performance of keeping humidity test experiments of the narcissus flower extract face cream of embodiment 4

Select 10 skin healths, the volunteer without cosmetic allergic contact dermatitis history.Before the test, left and right forearm is cleaned, is dried, 22 DEG C, relative humidity is stable 30min in 55% thermostatic constant wet chamber, after skin temperature and humidity reach balance with environment, In the pilot region that 3cm × 3cm is respectively marked on the forearm of left and right, left arm is blank control sample smear zone, right arm is testing sample Smear zone.The cuticula moisture that the CM825 moisture of skin test probe produced using German CK electronics corporations determines each position contains Amount, averages as test value.Then 0.1g samples (narcissus flower extract face cream or blank pair prepared by embodiment 2 is taken According to face cream) recipient site is applied to, behind 60,120,180 and 240min, keratoderma moisture is measured with method.

Moisture is one of important moulding material of epiderm skin cuticula, and horny layer of epidermis is thinning during skin senescence, cutin NMF content is reduced in layer, and skin hydration ability reduces, and moisture of skin, which is lost, to be accelerated.Pass through the survey to moisture of skin Surely the effect of degree and anti-aging cosmetics of skin senescence can be reflected indirectly.Fig. 2 is to use narcissus flower extract skin care After frost and control face cream, the situation of change of skin moisture-keeping.By Fig. 2 results showed that with the extension of time, blank It is smaller to compare the tested region change of moisture content of face cream, moisture is more slightly larger than before smearing, and this is due to that skin surface maintains Caused by itself water balance；And the tested region water content for smearing narcissus flower extract face cream is extension elder generation over time Slowly reduced after raising, this is due to that narcissus flower extract can keep the skin wet to skin surface, and can also be in skin table Face forms a tunic, reduces the speed of moisture evaporation.Therefore, appropriate daffodil chloroform extract is added in cream formula can To strengthen the moisture-retaining capacity of skin.
