D-mannitol 69-65-8
D-Mannitol is a hexavalent alcohol widely distributed in plants and plant secretions. It can be extracted from kelp or seaweed and is also obtained through the catalytic hydrogenation of glucose or sucrose. Natural products containing mannitol are commonly found in the leaves, stems, roots, and other parts of plants. For example, the white powder on the surface of seaweed and dried persimmons is mannitol. It is also present in high concentrations in edible fungi, lichens, onions, and carrots. The mannan obtained from the sap (secretions, dried) of Fraxinus ornus, a plant in the Oleaceae family, contains 30% to 50% mannitol.

Betulinic Acid 472-15-1
Betulinic acid is a pentacyclic triterpene compound that is widely found in nature. It was first isolated from the bark of evergreen plants of the Rhamnaceae family growing in Eastern Africa, but its main source is the bark of birch trees, from which it is extracted and purified. Recent scientific research has shown that betulinic acid (BA) is a very valuable natural product. BA and its derivatives have demonstrated significant potential as biological agents in the treatment of cancer and HIV. They play an important role in protecting the body from oxidative damage and in immune regulation. These compounds are considered highly promising drug leads and hold great potential for the development of new medicines. The U.S. National Cancer Institute (NCI) has included them in its Rapid Access to Interventional Development (RAID) program.

Advantages of Extracts
Advantages of D-mannitol 69-65-8
Low Caloric Value
D-Mannitol contains fewer calories than regular sugar, making it an ideal choice for low-calorie products.
Non-Cariogenic
Unlike sugars, D-Mannitol does not contribute to tooth decay, making it safer for dental health.
Versatile Usage
Easily incorporated into various manufacturing processes across industries.
Stability
Exhibits high stability under different temperatures and environments, which is vital for product formulation.
Enhanced Solubility
Improves solubility for many active pharmaceutical ingredients, ensuring better absorption and efficacy.
Advantages of Betulinic Acid 472-15-1
Anti-cancer properties
Some cancer therapies containing betulinic acids have shown effectiveness against brain tumors like glioblastoma. These compounds can potentially induce apoptosis or programmed cell death in malignant cells. They also disrupt cancer cell's ability to multiply and grow. This makes them useful in combating several types of cancers, including breast, prostate, and colon cancers.
Antiviral activity
Betulinic acid has proved effective in combating certain viruses. These include the herpes simplex virus and the cytomegalovirus. Its activity against HIV is particularly noteworthy. Some studies indicate that betulinic acid may help inhibit the replication of the HIV virus. This opens possibilities for using it in developing antiviral treatments.
Anti-inflammatory properties
Betulinic acid have anti-inflammatory effects. PHWs may treat conditions like arthritis by reducing inflammation and associated pain. They also help manage chronic inflammatory diseases, which are currently impossible to cure. These are diseases like inflammatory bowel disease (IBD) and asthma.
Neuroprotective effects
Betulinic acid may protect brain cells from damage, which could be beneficial in degenerative diseases. These include Alzheimer's and Parkinson's. Its ability to cross the blood-brain barrier is particularly valuable in developing treatments aimed at brain-related disorders. There is still a need for more clinical studies to fully understand its neuroprotective potential. However, early research suggests that betulinic acid could help slow or prevent the onset of neurodegenerative diseases.
