Honeysuckle Flower Extract

Honeysuckle Flower Extract: A Comprehensive Guide Introduction Honeysuckle flower extract, derived from the dried flower buds or first-opening flowers of the Lonicera japonica plant, is a valuable botanical substance with a rich history in traditional medicine and modern applications. This extract is primarily known for its high content of chlorogenic acid, a bioactive compound that serves as the cornerstone of its therapeutic properties. The extract is produced using advanced techniques such as supercritical fluid extraction and ultra-low temperature freeze-drying, ensuring the preservation of its active constituents. These methods contribute to the extract's efficacy, making it a preferred ingredient in pharmaceuticals, health supplements, and cosmetics. Botanical Source and Extraction Process The honeysuckle plant, scientifically named Lonicera japonica, belongs to the Caprifoliaceae family. It is widely cultivated in various regions, with China being a leading producer due to its favorable climate and soil conditions for the plant's growth. The extraction process involves carefully selecting the flower buds or early-opening flowers, which are then subjected to meticulous extraction techniques. Supercritical fluid extraction is a prominent method, utilizing carbon dioxide under high pressure to isolate the desired compounds without thermal degradation. This technique is followed by ultra-low temperature freeze-drying, which removes moisture while maintaining the integrity of the active ingredients, resulting in a fine brown powder with a consistent composition. Chemical Composition and Specifications The main active ingredient in honeysuckle flower extract is chlorogenic acid, which exists in several isomeric forms, including 3-O-caffeoylquinic acid and isochlorogenic acid B. These isomers contribute to the extract's diverse biological activities.
