What is Rosmarinic acid?
Rosmarinic acid is considered to be a natural, efficient and stable (high temperature durable), security, non-toxic and side-effects, water-soluble antioxidants and a green food additive. The medical research indicates that, it can eliminate the free radicals that over-produced by the body and annihilate the singlet oxygen to protect the structure of the cell membrane,which can slow down the aging process. In addition, it can stimulate and accelerate the metabolism of the fat by anti-oxidant activity. Not only can it lower the blood pressure, but it can also promote the lipid compounds to emit from the manure so as to lose weight.

Ursolic acid is a kind of natural triterpenoids,which has the activity of sedating, anti-inflammatory, antibacterial, resistance to diabetes, fight ulcer, antitumor, reducing blood fat, enhancing immune.Ursolic acid also has the function of obvious antioxidant, so it is widely used in medicine ,cosmetics materials and food emulsifier.
Ursolic acid is naturally presented in a large number of vegetarian foods, medicinal herbs, and other plants,such as Peppermint leaves,Bilberry and Elder Flowers.
The main function of rosemary is antioxidant, rosemary extract 3 mg / mL dose group can significantly improve the activity of SOD and CAT in fruit flies, reduce the MDA content. Rosemary extract can increase the activity of antioxidant enzymes in fruit flies, inhibit lipid peroxidation, with the role of anti-aging. In addition, rosemary extract rosmarinic acid and carnosic acid and natural organic fat has a strong affinity, therefore, rosemary often combined with organic fat made of creamy products. General cleaning supplies After cleaning, the functional components of skin care most of the water will be washed away, rosemary active ingredients in the affinity with the dough and skin affinity with the epidermis, this affinity beyond And water affinity, therefore, in the cleaning process, most of the active ingredients of rosemary can still be absorbed by the skin, play an antioxidant effect.
In addition, rosemary extract strong antioxidant can effectively stimulate the scalp blood circulation, sterilization itching, so the extensive use of hair care products.

At present, from domestic medicinal plants in the extraction of ursolic acid process basically has the following four kinds: (1) alcohol extraction → alkali treatment.
(2) alcohol → acid hydrolysis → alkali, chloroform treatment.
(3) alcohol extraction condensate.
(4) ultrasonic extraction method. Wusu acid is the anti-tumor, anti-oxidation, anti-inflammatory better a drug. In the case of its limited API, the search for the best extraction process , in order to improve the yield, thereby increasing its content, to a certain extent, the expansion of the drug source, which is very necessary.
Wusu acid is not ursolic acid?
Ursolic acid, also known as ursolic acid, ursolic acid, is from the Rhododendron Branch evergreen shrubs of the bear fruit from the extraction of a pentacyclic triterpenoid compounds, with a special smell in ethanol in the large and shiny Prism, and in dilute ethanol was fine like hair like needle crystal. Dissolved in methanol, ethanol, butanol, butanone, slightly soluble in acetone, slightly soluble in benzene, chloroform (methanol), methanol, ethanol, butanone, slightly soluble in acetone, slightly soluble in benzene, chloroform, soluble in dioxane, pyridine, mp285 ℃ ~ 288 ℃, , Ether, do not dissolve in water and petroleum ether.
2. What are the effects of ursolic acid?
With sedative, anti-inflammatory, antibacterial, anti-diabetic, anti-ulcer, lower blood sugar and other biological effects. In recent years, it has been found that it has anti-cancer, anti-cancer, induced differentiation of F9 teratoma cells and anti-angiogenic effect, most likely to become low toxicity and high efficiency of new anti-cancer drugs. In addition, ursolic acid has obvious antioxidant function, is a strong antioxidant, antioxidant effect of ursolic acid on the human body anti-aging, skin freckle, remove the pigment has a positive effect, which is widely used as Medicine and natural whitening cosmetics raw materials, experiments show that ursolic acid can inhibit the metabolism of arachidonic acid in the process of 5-lipoxygenase, cyclooxygenase activity, to prevent prostaglandin and leukotriene generation, which may be ursolic acid Inhibition of inflammatory response, inhibition of lipid peroxides.
3. Ursolic acid on cancer have no effect?
Ursolic acid is also a variety of carcinogenic, promoting cancer resistance, the study found that ursolic acid can significantly inhibit HL-60 cell proliferation, and induce apoptosis; can make mouse macrophage phagocytosis significantly increased, The inhibition of TSCCa cell growth was inhibited by about 12.5 U mol • L-1 in TSCCa cells. The in situ hybridization showed that ursolic acid inhibited the proliferation of TSCCa cells in TSCCa cell line in a dose- The inhibitory effect of the cells was related to inhibition of in situ expression of nuclear transcription factor. In vivo experiments show that ursolic acid can significantly enhance the immune function. Indicating that ursolic acid, a wide range of anti-tumor effect, ursolic acid is highly likely to become low toxicity and effective new anti-cancer drugs.
