Green thorn is a wild plant. In the 1920s, the famous Austrian botanist Dr. Joseph Locke conducted a 27-year investigation in Lijiang. He was pleasantly surprised to find that in the cold winter with thousands of flowers, the Jade Dragon Snow Mountain and the deep mountain valley on the shore of Lake Biwa The peculiar plants are proudly blooming with beautiful flowers. This strange plant is commonly known as the green thorn fruit in the local area. It is a wonderful flower in the world's woody oil plants. It is regarded as a "good luck tree" by the Naxi people, the Tibetan people and the Mosuo people. And "King of Flowers", the ancestors have been following the processing of green thorn fruit edible oil, and is widely used in folk health care, skin care, beauty, the effect is very effective.

Basic Information

Chinese name: green thorn fruit oil

Foreign name: prinsepia utilis rogle oil

    Mosuo people have a special liking for this. They use this oil as an essential product for their skin care and hair care. They are used to wipe the face, prevent dry and wrinkled skin, keep the skin soft and tender, and comb the hair with a comb. The oil of the hairdressing method is used to keep the hair black and shiny, not broken, not hair loss, and the like. Therefore, it is nothing new to keep a black hair in the old Mosuo old woman. Local ethnic minorities can live long-term consumption of green thorn fruit oil, and they can participate in labor or hunting when they are over 80 years old. It is precisely because of the above various good effects that the ethnic minorities have always regarded the oil as a "healthy protective oil" and "the medicine for treating all diseases" and cherish it as a treasure. I think this is the gift of nature to them. Every major festival, they must worship the gods. The Mosuo people use the oil to light the gods. The Muslims use this fried "oily fragrance" to commemorate God. The results of scientific research showed that the content of saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids in the thorn fruit oil was balanced. Green thorn fruit oil does not contain erucic acid harmful to human body, and is rich in vitamin E, A, etc. Its composition is very close to human lipids. Nutritionists call it "cosmeable cosmetics" and "human supplementation of essential fatty acids." The new source is a rare natural health supplement. In 1999, Beijing Ang Lida Technology Co., Ltd., Beijing Normal University, and Nankai University oil experts conducted scientific and technological research on the entry of green thorn fruit oil into the cosmetics field, and obtained satisfactory results.

Skin care products; green thorn fruit oil; moisture retention

Green thorn fruit oil is a kind of pure natural skin care oil, which is very close to human body lipids, so it is very easy to be absorbed by human skin and can maintain the skin's moisture, nutrition and elasticity. The green thorn fruit, the alias grabs the fruit, is called the green thorn in the "Southern Materia Medica", the gun thorn fruit in the Qujing area of Yunnan, the Axis of the Lijiang Naxi, and the altitude of 1 400 m~ in Yunnan, Guizhou and Sichuan. 3 100 m on the slopes and wasteland. The average oil yield of green thorn fruit is 28%. The fruit oil is rich in various nutrients needed by the human body. It is a high-grade natural edible oil, which is important for the treatment of high blood fat, cholesterol reduction and cardiovascular disease prevention. effect. Green thorn fruit oil is rich in vitamins and unsaturated fatty acids. The content of oleic acid and linoleic acid is over 70%, but it does not contain erucic acid which is harmful to human body. It has high edible, medicinal value and unique beauty. Skin care effect.

The green thorn fruit is a treasure, has been used for a long time in the folk, and has a long history and extensive use in skin care and beauty. In the Dongba scriptures of the minority areas of Lijiang Naxi, Yi and Mosuo, it is recorded that the green thorn oil can be applied to the skin to prevent mosquito bites or eliminate the swelling caused by bruises, prevent dry skin, itching and cure frostbite. Rubbing the hair with green thorn oil can inhibit the hair from falling off, and has the effect of blackening the white hair; local skin burns and burns, applying the green thorn oil to the affected area can prevent wound infection and accelerate wound healing without leaving scars. In the local folk, the skin of the newborn baby is applied with the green thorn oil, which can promote the falling off of the baby's baby hair and make the skin dry and smooth.

Chemical composition and pharmacology

Studies have shown that the fatty acid composition of thorn fruit oil is mainly composed of unsaturated fatty acids - oleic acid and linoleic acid, of which oleic acid content is 33.38% and linoleic acid content is 40.82%; in addition, 17.2% palm is contained. Acid and 6% stearic acid, and contains a variety of vitamins such as vitamin A, vitamin D, vitamin E and vitamin K. Each 100 g of green thorn fruit oil contains 3.5 mg of vitamin A, 2.1 mg of vitamin D, 11.2 mg of vitamin E and 0.30 mg of vitamin K also contains very rich macro and trace elements such as calcium, sulfur, manganese, magnesium, potassium, phosphorus, zinc and iron. Compared with other edible oils, the highest content of potassium is 9.8 mg. /kg. Potassium plays an important role in maintaining the normal metabolism of carbohydrates, proteins and normal muscle functions, and regulating the normal acid-base balance inside and outside the cell and lowering blood pressure.

Greenthorn fruit oil is rich in monounsaturated fatty acids compared to other vegetable oils. Studies have shown that monounsaturated fatty acids such as oleic acid, palmitoleic acid and giant whale acid can lower blood cholesterol and low-density lipoproteins that are detrimental to cardiovascular health, but do not reduce beneficial high-density lipoproteins. Foods rich in monounsaturated fatty acids have the effect of relieving hypertension and anti-atherosclerosis, while monounsaturated fatty acids have properties that are not easily oxidized. Experiments on the effects of thorn fruit oil on blood lipids and antioxidant capacity of hyperlipidemic rats showed that thorn fruit oil has certain functions of regulating blood lipids, anti-oxidation and inhibiting platelet aggregation in vitro.

After the same comparison and testing of Yunnan Baiyao Group Shanghai Transdermal Technology Co., Ltd., the penetration performance of green thorn fruit oil is good, reaching various technical requirements. Compared with Mediterranean olive oil, each index is better than the other, and its fatty acid composition ratio is very high. It is close to the human body's lipid composition, so it has good affinity with the skin and is a good cosmetic base material. The skin care effect of the green thorn fruit oil was further studied through the skin moisturizing test.

2.3 Experimental methods

2.3.1 Test crowd

Number of participants: 15; Age: 20 to 40 years old; Gender: 10 females, 5 males; Health status: Subjects with healthy skin, no skin disease and allergies.

The test environment temperature was 25 ° C, and the relative humidity (RH) was 61%. The test site was exposed 10 minutes before the measurement, and the subject was quiet in this environment. A 3.5 cm × 3.5 cm square experimental area was drawn on each of the left and right forearms, and the experimental area was numbered. The left arm was used as the test area for applying the green thorn oil cream, and the symmetrical area of the right arm was the test area using the blank control product. . First wash the test area with alkaline soap, rinse and dry. Prior to the application of the cosmetic, the Corneometer CM 825 tester was used to determine the moisture content of the stratum corneum of the test site. 0.1 g of the experimental product was applied to the test site and spread evenly on the skin for 2 min. Single and continuous measurements were performed at 10 min, 40 min, 60 min, 120 min, and 180 min using the Corneometer CM 825 tester to test the skin horny layer moisture content (measured in au) and record The test results are shown in Figures 1 and 3. 10 points were selected for measurement in the test area, and the average value was recorded as a single test. At the same time, the intermediate point was selected in the test area for measurement for 70 s, and the average value was recorded as continuous test. In order to better evaluate the data obtained, the concept of the skin moisture retention rate is introduced, that is, the difference between the moisture content measured after using the product and the moisture content of the unapplied product, and then divided by the moisture when the product is not applied. The content value, the result is the skin moisture retention rate. By calculating the percentage of skin moisture change at different time points using the two test products, it is good to evaluate whether the product has moisturizing and moisturizing effects.

After using the two test samples, the skin moisture content of the skin has different degrees of improvement, especially the skin cream containing green thorn fruit oil, the value of the skin moisture content reaches the highest at 40 min.

Through calculations to compare the effects of green thorn oil skin cream and ordinary skin cream on the change of skin moisture content, the two test products have a certain degree of improvement on skin moisture, but after 40 minutes of use, the green thorn fruit oil skin cream moisturizes The rate of sexual improvement reached 85.71%, while the blank control group was only 46.88%. The moisturizing rate of skin care products added with green thorn fruit oil after 180 minutes was still greatly enhanced, indicating that the green thorn fruit oil has a strong moisturizing effect.

After continuous testing, the moisture content of the epidermis was increased after using the green thorn fruit oil product, especially in the 10 min~40 min period, the skin moisture content increased rapidly and then stabilized. This value is higher than the untreated thorn fruit oil product at different time points.

The green thorn fruit oil has a certain improvement on the skin's moisture retention, especially in the use of 10 min ~ 40 min, the skin moisture retention improved faster. Over time, the skin moisture retention rate decreased slightly, but it was still significantly higher in the test time range (180 min) than in the untreated green fruit oil.

The health of the skin is closely related to the moisture content of the stratum corneum. When the water content of the stratum corneum is less than 10%, the stratum corneum becomes brittle and easy to crack. Therefore, it is necessary to select high-efficiency moisturizing active ingredients in skin care products to improve the moisturizing effect of the skin. very important. The effect of skin care products on the skin is reflected by changes in skin moisture content, mainly by skin moisturizing experiments, which is one of the most widely used skin testing methods. The use of the Corneometer method to evaluate whether a component has a moisturizing function is an objective evaluation method with high sensitivity, reproducibility and adaptability.

In this experiment, a matrix blank paste and a paste containing 5% green thorn fruit oil were used as a control group for moisturization study. The results showed that the tester used the skin care product containing 5% green thorn fruit oil to test the skin moisture content at the 10th, 40th, 60th, 120th and 180th time points. The single test and continuous test results showed The value of moisturizing improvement of skin cream containing green thorn fruit oil was significantly higher than that of blank control group without thorny fruit oil. The skin's stratum corneum maintains a large change in water capacity. Temperature, humidity, medicines and cosmetics can determine and change the moisture content in the skin. Therefore, it is useful to quantitatively test the skin moisture content and the amount of change after a certain period of care. . When evaluating the strength of the moisturizing effect of cosmetics, it is suitable to do a short-time coating test (<180 min), and the moisture content of the stratum corneum can be determined by this method, and the moisturizing effect of the product can be analyzed. The water retention xxx of the epidermis depends on two basic factors: the anti-evaporation of the sebum membrane and the water absorption capacity of the natural wetting factor. The sebum membrane on the surface of the skin is a mixture of sebum and sweat. It is composed of lactic acid, amino acids, urea, uric acid, salt, neutral lipids and fatty acids. It has the effect of moisturizing the skin, preventing excessive evaporation of water and regulating the pH of the skin surface. The component of the stratum corneum that binds to water molecules is called a natural moisturizing factor. The thorn fruit oil has obvious osmotic effect on the skin, mainly because its composition is consistent with the composition of the natural moisturizing factor in the stratum corneum, so it is easy to penetrate into the skin and form a secondary bond with the free water in the stratum corneum. The network structure of water or associated water makes it easy to lose moisture and has a good moisturizing effect. It can be seen from the above experiments that the green thorn fruit oil can be used as a moisturizing additive for cosmetics.

The low-temperature extraction of the thorn fruit oil retains the pure natural bioactive ingredients, the main components of which are polyunsaturated fatty acids and monounsaturated fatty acids, which are very close to human lipids, so the penetration of the skin is particularly good, human skin. It is also very easy to absorb, can maintain the moisture, nutrition and elasticity of the skin. It is the raw material for the natural skin care products that are rare in the cosmetics industry today. The current trend of cosmetics in the world today is to return to nature, green and environmentally friendly, and to replace chemical synthetic raw materials with pure natural materials. Green thorn fruit oil is such a pure natural skin care oil, which has broad application prospects.
