II. Product Introduction
1. Source
Luteolin is primarily produced from honeysuckle flowers through a series of processes including impurity removal, pulverization, extraction, filtration, concentration, purification, and drying, which effectively preserve the structural integrity and relevant properties of luteolin. The raw materials undergo rigorous screening to remove impurities, adhering to industry standards for plant extract processing and catering to diverse application needs across multiple fields. Different purity grades are available to meet the requirements of various use scenarios.
2. Core Efficacy and Applications
(1) The pharmaceutical field
Luteolin (CAS: 491-70-3) exhibits relevant biological activities and holds considerable value in research on antioxidant and anti-inflammatory effects. It can be used as a pharmaceutical raw material in the development and production of related formulations. Any related applications must comply with pharmaceutical industry standards, clinical study findings, and national food safety regulations.
(2) The field of feed additives
As a natural active ingredient, luteolin can be used as a feed additive in livestock and poultry farming. Thanks to its anti-inflammatory and antioxidant properties, it helps regulate the metabolism of livestock and poultry, improves farming quality, and aligns with industry trends toward green and antibiotic-free farming. The use of luteolin in feed must comply with relevant feed industry standards and adhere to specified addition levels.
(3) Food Preservation Field
Luteolin exhibits excellent antioxidant and antibacterial properties, making it suitable as a natural food preservative in food processing. It can delay food oxidation and spoilage, inhibit the growth of harmful microorganisms, and extend the shelf life of various foods, including fruits and vegetables, meat products, grains, and oils. It complies with industry standards for natural food additives.
