About Loquat Leaf Extract Powder
Loquat Leaf Extract is a powder derived from the dried leaves of Eriobotrya japonica (Rosaceae). Its core active ingredients include ursolic acid (a triterpenoid compound) and flavonoids, with KinTai primarily offering ursolic acid and corosolic acid powders. This extract exhibits various pharmacological effects: ursolic acid possesses antibacterial, anti-inflammatory, and antioxidant properties, while corosolic acid can regulate blood glucose and promote metabolism. Additionally, both compounds work synergistically to exert lung-protective and cough-relieving effects. Consequently, Loquat Leaf Extract is widely applied in fields such as pharmaceuticals, health products, and functional beverages.

Ursolic Acid Powder
Ursolic acid powder is a natural triterpenoid compound extracted from plants, widely found in plants such as rosemary and bearberry, and has numerous potential applications. Kintainutri®, a trusted Chinese plant extract manufacturer, specializes in producing high-quality rosemary extract ursolic acid powder, making it a reliable choice within the industry thanks to its exceptional strength.
Corosolic Acid Powder
Corosolic Acid is a natural pentacyclic triterpenoid compound primarily extracted from Loquat Leaf and Banaba Leaf . It is a high-purity active ingredient renowned for its significant biological activities and health benefits. Corosolic Acid typically appears as a brown powder, soluble in organic solvents, and is widely used in the nutraceutical, pharmaceutical, and cosmetic fields.

1.Safe and natural olive leaves
Loquat Leaves are naturally safe, derived from their natural growing environment with no pesticide residues. The extraction process protects the active ingredients throughout, avoiding damage from acids, alkalis, high temperatures, sunlight and chemical solvents, thus maximizing the retention of the natural state and safety of the active substances.
2.High content of ingredients
The content of polyphenolic compounds in loquat leaves is significantly higher than that in olive fruits and barks, especially rich in key active ingredients such as oleuropein and hydroxytyrosol, which constitute a strong material activity foundation.
3.Excellent bioavailability
Loquat Leaf Extract powder possesses antibacterial, anti-inflammatory and strong antioxidant properties. It can not only promote the reaction to kill bacteria in the early stage of inflammation, but also inhibit inflammation and promote cell proliferation in the later stage. It has strong structural stability, high bioavailability and a long duration of action.
