Technical Field

The invention relates to the field of plant extracts and daily chemicals, in particular to application of a myrobalan alcohol extract.

Background

The skin covers the surface of a human body and is in direct contact with the external environment, so that the human body can be protected from being damaged by various external factors, and the human body can be used as a mirror to reflect the health state of the human body. The skin is composed of epidermis, dermis, and subcutaneous tissue, and contains skin appendages, abundant nerves, blood vessels, lymphatic vessels, and muscles. The connective extracellular matrix region of the dermis and epidermis, also known as the Basement Membrane (BM), not only supports the epidermis, but also serves multiple functions, such as the junctions of the dermis and epidermis acting as a selective cellular barrier that generally prevents connective tissue cells from contacting the epidermal cells of the Basement membrane, but allows passage of lymphocytes, macrophages, and neuronal synapses; in addition, many vital phenomena such as cell morphology, cell polarity, cell metabolism, protein distribution in plasma membranes, cell survival, cell proliferation and differentiation, and cell migration are very closely related to the basement membrane. Nestin and perlecan are important components of basement membrane, essential for maintaining the structure and function of basement membrane, which is essential for maintaining normal renewal of skin. The dermis is composed of cells and extracellular matrix, and fibroblasts are main cells of the dermis, and the normal proliferation and differentiation of the fibroblasts maintain the structure of the dermis of the skin and form normal structure and physiological functions; extracellular matrix is a kind of macromolecular substance synthesized and secreted by cells and interacting around the cells, and many life phenomena such as proliferation and differentiation of cells, cell migration and the like are closely related to the extracellular matrix. The extracellular matrix is composed of four major classes of molecules: collagen, elastin, glycoprotein and proteoglycan. The extracellular matrix is finely and skillfully entangled and interwoven through different molecules to form various exquisite three-dimensional structures, so that the skin is endowed with elasticity and tensile strength, and looks plump and full of vitality.

fibroblast growth factor 7 (FGF 7) gene encodes a Fibroblast growth factor 7 mitogenic and cell survival activity and is involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. The protein is an effective epithelial cell specific growth factor, the mitogenic activity of the protein is mainly shown in keratinocytes, and the protein has the effect of resisting aging.

Fibrillin 1 encoded by FBN1(Fibrillin 1) gene is secreted by fibroblasts of dermis into extracellular matrix, and can be used as structural component of calcium-binding microfibril to provide stress structure for elastic and inelastic connective tissues of whole body and mediate a series of cell and matrix interactions. Is an important component of elastic fiber in connective tissue, in the process of forming the elastic tissue, the fibrillin 1 provides a skeleton for storing the elastin, the periphery of the mature elastic fiber grows, the reduction of the skin elasticity is an important characteristic of skin aging, the expression level of the fibrillin 1 is closely related to the skin elasticity, and the reduction of the expression level of the fibrillin 1 is also a key factor causing the skin aging.

the protein encoded by the CSF2(colony stimulating factor 2) gene is colony stimulating factor 2, also known as granulocyte macrophage colony stimulating factor, is a broad-spectrum cytokine, and has a proliferation promoting effect on early hematopoietic progenitor cells. Mainly acts on myeloid progenitor cells, exerts biological effect by binding with high affinity receptors thereof, enables the cells to rapidly enter the cell cycle and differentiate towards the granulocyte line and macrophage line, finally becomes mature cells, can prolong the life of the mature cells, enhances the functions of the mature cells and resists skin aging, so the colony stimulating factor 2 is an important cell longevity factor.

The heparin binding epidermal growth factor hbegf (heparin binding EGF like growth factor) is a member of the EGF family that binds to and activates EGF receptor growth factors. HBEGF plays a key role in pathophysiological processes, including cancer. After the partial thickness of human skin is damaged, epidermal growth factor is generated to promote cell proliferation and be beneficial to healing of skin wounds, and meanwhile, EGF is the epidermal growth factor to promote the proliferation of epidermal cells and maintain the young state of the skin.

The major function of Tenascin-C, also known as Tenascin-C (TNC), encoded by the TNC (Tenascin-C) gene is to strengthen the connective tissue, highly expressed during embryonic development and tightly regulated, while being barely detectable in normal adult tissues. The up-regulation of TNC expression in adult tissues is usually associated with disease states such as inflammation, injury, tumor neogenesis and the like. TNC is used as an important non-structural extracellular matrix protein and participates in a tissue injury repair process, the increase of the expression level of TNC can reflect the increase of the proliferation rate of skin, and the skin can be helped to resist aging.

Latent transforming growth factor beta binding protein 1 encoded by LTBP1(late transforming growth factor beta binding protein 1) gene belongs to the latent TGF-beta binding protein (LTBP) family. The secretion and activation of TGF-beta is regulated by its association with latent associated proteins and latent TGF-beta binding proteins. Transforming growth factor (TGF-beta) is a kind of cytokine with multiple effects and complex functions, and is involved in cell growth, tissue repair and wound healing, generation of blood vessels and scars, and generation and metastasis of tumors. Therefore, the latent transforming growth factor beta binding protein 1 is closely related to skin wound healing, tissue repair and anti-aging.

The β 4 subunit of integrin encoded by the ITGB4(Intergrin- β 4) gene, an essential family of cell surface receptors, mediates adhesion to cells and the extracellular matrix. Integrin beta 4 subunit binds to alpha 6 subunit and is an important component of hemidesmosomes in basement membrane. The integrin beta 4 subunit is positioned in epidermal basal layer keratinocytes and is an important cell proliferation capability marker, and meanwhile, the expression up-regulation of the ITGB4 gene can promote the expression of the integrin beta 4 subunit, further promote the stability of a basement membrane structure, strengthen the tight connection of the true epidermis and resist skin aging.

Therefore, the research on how to improve the expression of genes related to key parts and functions of the skin has important significance for improving the stability of the true epidermal structure of the skin and delaying skin aging.

myrobalan, from Ben Cao Tu Jing, is a Chinese medicine with effects of refreshing and removing toxic substance, and is mainly used for treating chronic diarrhea, chronic dysentery, rectocele, cough and asthma with phlegm, and chronic cough with aphonia. The book Ben Cao Jing Shu of Ming Dynasty records "Chebulae Lei le with bitter and astringent taste and no toxicity due to its warm nature. Bitter flavor with diarrhea, astringent flavor with astringency, warm flavor with purgation, astringing flavor with astringency with cold-producing effect, and fullness and distention in the heart and abdomen; it can be eaten only because of its warm nature. The right of the physician is to stop the passage of water, the herb of stranguria to stop the chronic diarrhea of intestine, the herb of Susong to treat the diarrhea and leukorrhagia due to intestinal wind, the herb of Zhu Zheng Heng to strengthen the large intestine without bitter and astringent actions. The record of the Ming's medical book (Yao Huayi) states that myrobalan has bitter taste and sour and astringent flavor, can descend and recover, and is good at both sides, wheezing when the myrobalan is covered with gold, lung qi is the stagnation of fire pathogen, so that wheezing and cough are caused, or the myrobalan is hoarse, when the myrobalan is used for depressing and astringing the lung, no obstruction of lung orifices is caused, and the sound is clear . Its astringency can be removed. If chronic diarrhea or dysentery occurs, the excess pathogen will remove the original qi, so it is combined with spleen-tonifying herbs to astringe large intestine and stop diarrhea or dysentery. Myrobalan is the most commonly used Tibetan medicine. In the classic book of Tibetan medicine, "Jingzhu Bencao" in Tibetan medicine, the myrobalan is called "the king of Tibetan medicine". In the classic monograph of Mongolian medicine, "gold light annotation Collection", the following records are: myrobalan has bitter taste on its root surface, pungent taste on its tip, sour taste on its middle fleshy part, astringent taste on its outer skin, and sweet taste on its core. While the other Mongolian medical works describe myrobalan as follows, the tip pungent part mainly treats various diseases such as 'hei' and 'Ba Da gan', the sweet taste of the fleshy part close to the nucleus can treat 'Hila' disease, and all the tastes can treat syndromes caused by various factors.
