I. Introduction of plant extract Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods. Plant extracts are products formed by directional acquisition and concentration of one or more active ingredients in plants without changing the structure of the active ingredients. According to different ingredients, plant extracts can be divided into glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids and other categories; according to different product properties, they can be divided into vegetable oils, extracts, powders, lenses and other categories. It is a very important intermediate product with a wide range of applications and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries. II. Popular Plant Extracts - A spotlight on popular plant extracts in the wellness industry (i.e., Centella asiatica extract, aloe vera extract, etc.) Centella asiatica extract Centella asiatica, commonly known as Indian pennywort and Asiatic pennywort, is an herbaceous, perennial plant in the flowering plant family Apiaceae, which has a wide range of uses. Unveiling the Powers of Plant Extracts 1. Antibacterial Centella asiatica extract contains asiatic acid and madecassic acid, these active saponins acidify the cytoplasm in plant cells, this antibacterial activity protects the plant itself against the attack of mold and yeast, Experiments show that Centella asiatica extract has a certain inhibitory effect on Pseudomonas aeruginosa, Staphylococcus aureus and Propionibacterium acnes. 2. Anti-inflammatory Asiaticosides have obvious anti-inflammatory effects: reduce the production of pro-inflammatory mediators (L-1, MMP-1), improve and repair the skin's own barrier function, thereby preventing and correcting skin immune dysfunction. 3. Heal wounds and scars This effect of Centella asiatica is widely used in dermatology clinical treatment. Madecassoside and Madecassoside are the active ingredients of Centella Asiaticoside in treating burns and healing wounds. They can promote collagen synthesis and new blood vessel formation in the body; stimulate granulation growth and other important functions, so they are beneficial to wound healing. At the same time, asiaticoside has a proliferation effect on epidermal keratinocytes and vascular endothelial cells, and has an inhibitory effect on fibroblasts, so as to promote the formation of granulation tissue in the early stage of wound healing and inhibit scar formation in the late stage of wound healing. 4. Anti-aging Centella asiatica extract can promote the synthesis of collagen I and III, as well as the secretion of mucopolysaccharides (such as the synthesis of sodium hyaluronate), increase the water retention of the skin, activate and renew skin cells, and soothe the skin. On the other hand, through DNA array test research, it was found that Centella asiatica extract also has the activation effect of fibroblast gene, which can enhance the vitality of skin basal layer cells, maintain skin elasticity and firmness, and smooth fine wrinkles on the face. 5. Antioxidant Madecassoside, asiatic acid and madecassic acid all have obvious antioxidant activity. In addition, asiaticoside is also a good inhibitor of apoptosis induction, by reducing the concentration of oxygen free radicals in tissue cells; it has obvious biological effects on cell apoptosis inducing bases on tissue cells. Aloe vera extract Aloe vera extract is a colorless, transparent to brown, slightly viscous liquid that turns into yellow fine powder after drying. Aloe extract is the extract of Aloe vera, Aloe sinensis, Aloe saponaria, etc. which have medicinal value in Aloe of Liliaceae. The extraction methods of aloe extract mainly include solvent extraction and ultrasonic extraction, and mainly contain active ingredients such as anthraquinones and polysaccharides. Aloe extract is mainly used in cosmetics, health care products, food and medicine. Unveiling the Powers of Plant Extracts Aloe extracts have been approved for the treatment of AIDS in humans. According to researchers, aloe vera contains at least 140 kinds of ingredients, including ingredients that control cell growth and differentiation, anti-infection ingredients, ingredients that stimulate the growth of white blood cells and other immune cells, and ingredients that promote wound healing. Aloe also has the functions of enhancing immunity, promoting intestinal peristalsis, radiation protection, and cardiovascular disease prevention. In addition, aloe vera is also widely used in surgery, ENT, internal medicine, gynecology, pediatrics, cancer treatment, geriatric diseases. Aloe vera extract is a natural extract, which contains a variety of moisturizing ingredients and nutrients that are beneficial to the human body.
