Product Description

Loquat Leaf Extract: Natural Source of Corosolic Acid

Loquat Leaf Extract, also known as Eriobotrya japonica leaf extract or "biwa cha," is valued for its high content of corosolic acid, a bioactive compound known for supporting metabolic health, antioxidant activity, and healthy inflammatory response. Corosolic acid, a natural triterpenoid, works synergistically with other plant compounds like oleanolic acid and amygdalin, enhancing the extract's holistic wellness benefits.

In the market, loquat leaf extract is widely used in dietary supplements and functional beverages, appealing to consumers seeking natural, plant-based solutions. Product quality varies with sourcing, extraction methods, and corosolic acid content, which directly affects efficacy.

Our facility specializes in producing premium loquat leaf extracts standardized for corosolic acid, a bioactive compound renowned for supporting healthy glucose metabolism, metabolic balance, and antioxidant protection. Our production process ensures the highest integrity of corosolic acid, from carefully selecting leaves grown in optimal climates to applying gentle, precision extraction methods that preserve its bioactivity.

Unlike standard suppliers, we offer flexible OEM and formulation support, allowing brands to tailor corosolic acid content, delivery formats (powders, tinctures, or blends), and complementary herbal combinations. With consistent quality, scalable production, and clean-label compliance, our extracts enable partners to develop high-performance, market-ready products that meet the growing demand for natural, science-backed metabolic health solutions.
