What is Lagerstroemia Speciosa Leaf Extract?

Research results in recent years have shown that the lagerstroemia speciosa leaf extract is rich in polyphenols, tannic acid, multiple amino acids and dietary fiber. The active ingredients corosolic acid and ellagitannins have anti-diabetic and anti-obesity effects. In particular, corosolic acid has anti-hyperlipidemic and antioxidant activities, which is beneficial to enhance the cell's uptake of glucose, thereby reducing blood sugar levels.

Lagerstroemia Speciosa Leaf Extract Details

Lagerstroemia speciosa is mainly produced in the Philippines and other Southeast Asian regions. In India, the roots of the tree are used as astringents; in Malaysia, the leaves of the tree are often used to treat malaria and fractures; in the Philippines, people have the custom of making tea from its leaves. It is said that drinking this tea regularly has the magical effect of reducing postprandial high blood sugar, and it is known as "natural plant insulin."

Kintai's Production Process of Lagerstroemia Speciosa Leaf Extract

1. The leaves of Lagerstroemia indica were used as raw materials, and pure water 10 times the dry weight of the plant was used to boil for 2 hours, the extracts were combined, filtered, and the filtrate was concentrated into an extract by vacuum.
2. 50% ethanol solution was added to the filter residue, and the pH value of the solution was adjusted with sodium hydroxide. Extraction was performed at 30°C, and the pH value of the filtrate was adjusted to 4.5. The mixture was allowed to stand for aging, and the solid-liquid separation was performed. The precipitate was the crude product of total triterpene acids.
3. Then, the mixture was purified using a macroporous adsorption resin, and the mixture was slowly cooled until corosolic acid crystals began to precipitate. The mixture was refrigerated, and the crystals were allowed to stand for crystal growth. The precipitate from the solid-liquid separation was corosolic acid.

Market of Lagerstroemia Speciosa Leaf Extract

With the increase in diabetes cases across the globe, the market for lagerstroemia speciosa leaf extract is set to expand rapidly, especially in countries like India, which is known as the diabetes capital of the world. The beneficial properties of corosolic acid in the extract can treat serious diseases including cancer and kidney failure. The pharmaceutical and healthcare industries have the highest demand for this chemical as patients battle diabetes on a daily basis.​​​​​​

​​​​​​​Corosolic acid is primarily used to treat type 2 diabetes because it reduces insulin resistance in patients. As the pandemic subsides, it has left many post-recovery side effects in COVID patients, with diabetes being one of the most prominent. Corosolic acid inhibits the proliferation of these cells by increasing the absorption of glucose in the body.

Moreover, it can also reduce the incidence of tumors in patients. This is considered to be very beneficial for diabetic patients and those suffering from liver cancer caused by diabetes. As corosolic acid has immense benefits in the pharmaceutical and medical industries, this development will increase the market growth.

In the study of the effect of Lagerstroemia speciosa on the treatment of type II diabetes, it was found that female mice fed a diet containing Lagerstroemia indica extract had an anti-obesity effect. The researchers believed that th is was due to the reduction in the accumulation of triglycerides, indicating that Lagerstroemia speciosa extract has a lipid-reducing effect.
