Grapefruit plant extract is obtained from the seeds, pulp, and peel of Citrus paradisi through pressing and aqueous-glycerin extraction. The extract is rich in flavonoids, particularly naringin, naringenin, and limonoids, along with organic acids and tocopherols.
Grapefruit seed extract (GSE) is well-known for its broad-spectrum antimicrobial activity against bacteria, fungi, and parasites. The extract also demonstrates antioxidant and metabolic support properties. Commercially, it is used in natural antimicrobial supplements, food preservation systems, cosmetic formulations, and household cleaning products.
