Description

The new opplication of Herba Fici Simplicissimae and extract thereof
Technical field
The present invention relates to technical field of Chinese medicines, relate to the new opplication of Herba Fici Simplicissimae and extract thereof specifically.
Background technology
The colour of skin is that people examine one of standard of beauty.For Asia women, the pale colour of skin especially one is generally pursued.For this reason, various product arises at the historic moment, as: whitening products, anti-ultraviolet product and film product etc.After deliberation, skin color is comprehensively determined by various pigments contained in Skin Cell.In numerous pigment, melanin amount contained in melanocyte is topmost determiner.Further research confirms, tryrosinase (EC1.14.18.1) is the key enzyme of B16 cell.Thus, active by restraint of tyrosinase, generate to reduce melanin, thus the skin effect reaching whitening becomes one of the important evidence of research and development skin-protection product (Chinese journals of practical medicine [J], 2005,21,1364-1366; Xiamen University's journal (natural science edition) [J], 2007,46,274-282).Whitening agent conventional in these products as: hydroquinone, kojic acid, arbutin etc. are several, and these materials more or less have suitable cytotoxicity.Therefore, the safety of tyrosinase inhibitor needs the factor considered of laying equal stress in whitening and skin-protecting R & D of complex, and the selection of Chinese herbal medicine is easy to be esthetically acceptable to the consumers undoubtedly in this respect more.
Herba Fici Simplicissimae, another name Ficus hirta, Herba Ipomoeae Cairicae, milk root, southern stilbene, there are medicinal record in multiple nationalitys such as Guangxi, Guangdong, Yunnan, and the ground such as main product Guangxi, Guangdong, are described as " panacis quinquefolii radix ".Herba Fici Simplicissimae is the root of Moraceae ficus species ficus simplicissima (Ficushirtavahl.).Herba Fici Simplicissimae for health care, has spleen invigorating to dry among the people, effect of relieving cough and resolving phlegm, dredge the meridian passage, the use history having more than one thousand years among the people in Guangdong.(the number of patent application: 200510002111.7) disclose the novelty teabag of Herba Fici Simplicissimae in preparation hepatitis adjuvant therapy medicaments and health food such as the Zhang Baoxu of Peking University.The Yuan Lixia (application number: 201010274140.X) of Nanfang Medical Univ discloses a kind of pharmaceutical composition preventing and treating viral myocarditis and preparation method thereof.Wang Xiao equality (Wang Xiao equality, the experimentation of Herba Fici Simplicissimae Aqueous extracts vitro antibacterial activity, time precious traditional Chinese medical science traditional Chinese medicines, 2010,21 (7): 1692-1693.) report Herba Fici Simplicissimae Aqueous extracts all inhibited to escherichia coli, bacillus subtilis, staphylococcus aureus, minimum inhibitory concentration is 1g/ml.In addition report Radix Fici Simplicissimae extract is also had to have anti-inflammatory, anti-acid and aging-resistant effect.But Herba Fici Simplicissimae is mainly applied and is only limitted to above-mentioned several aspect at present, deep research report also be yet there are no to other using value of its extract.
Chinese patent CN103877283A discloses the herb liquid of a kind of whitening and speckle dispelling, eliminating toxin and beautifying the skin, and it obtains with the 10 kinds of Chinese medicines composition compound recipe decoctings comprising Herba Fici Simplicissimae, can restraint of tyrosinase active, there is effect of whitening and speckle dispelling and eliminating toxin and beautifying the skin.But the realization of this effect is based upon on whole Chinese medicine compound combined effect basis, this patent unexposed Herba Fici Simplicissimae or Radix Fici Simplicissimae extract separately can restraint of tyrosinase active, and there is the effect of skin whitening.
There is not the record of beautifying whitening related efficacy in Herba Fici Simplicissimae, have no the purposes of Herba Fici Simplicissimae as tyrosinase inhibitor, and Herba Fici Simplicissimae is applied to the report of skin-lightening cosmetic in prior art in Chinese medicine is recorded yet.
Summary of the invention
In view of this, the object of the present invention is to provide Herba Fici Simplicissimae and extract thereof in the relevant application of a series of beautifying whitening, be mainly included in prepare tyrosinase inhibitor, Melanin inhibitor, skin-lightening cosmetic and skin-whitening, the new opplication prevented in melanin deposition.
At the field of Chinese medicines, effect of Herba Fici Simplicissimae is recorded and is only limitted to the merit with strengthening the spleen and tonifying the lung, circulation of qi promoting dampness removing, relaxing muscles and tendons and activating QI and blood in the collateral, the traditional Chinese medical science of Lingnan area or ethnic groups doctor among the people are usually used in treating that insufficiency of the spleen edema, lack of appetite are unable, pulmonary tuberculosis cough, night sweat, leukorrhagia, puerperal agalactia, menoxenia, rheumatic arthralgia, the disease such as edema.And the present invention finds through creative research, Radix Fici Simplicissimae extract has the ability of restraint of tyrosinase activity preferably, can be used in the preparation of skin-whitening and relevant cosmetics.
