Dimocarpus longan · dragon's-eye
Dimocarpus longan is a tropical evergreen tree native to Southeast Asia and widely cultivated in various regions, including China, India, and Sri Lanka. Traditionally, its fruit has been consumed for its sweet flavor and believed to have restorative properties, but specific medicinal uses are not well-documented. Scientific evidence suggests that longan polysaccharides may enhance immune responses, potentially making them useful as adjuvants in vaccine formulations. Additionally, topical application of 3% WIN-1001X cream containing longan extract has shown promise in improving wound healing by reducing inflammation and promoting cell proliferation and collagen deposition in diabetic mice. In fish, fermented longan peel supplementation improved growth performance and immune response, indicating potential benefits for animal health. The identification of 71 DlPP2C genes, including the ABA-responsive DlPP2C1, further highlights its biological significance but does not directly translate to human applications. No major safety concerns or drug interactions have been reported thus far.

Ce que dit la science
- Le polysaccharide du longan (LP) a renforcé à la fois les réponses immunitaires humoraux et cellulaires chez les souris lorsqu'il a été formulé avec un antigène modèle, suggérant son potentiel comme adjuvant sûr.
- L'application topique d'une crème à 3% WIN-1001X a amélioré la cicatrisation des lésions en réduisant l'inflammation et en favorisant la prolifération cellulaire et la déposition de collagène chez les souris diabétiques.
- Une supplémentation par la peau de longan fermentée à 20 g kg-1 a amélioré le performance de croissance, l'activité des enzymes digestives, la structure intestinale et la réponse immunitaire chez la truite nile.
- L'étude a identifié quatre groupes génétiques chez le longan avec une variation hétérogène au sein des groupes et un intervalle candidat sur le chromosome 11 montrant un potentiel d'éviction sélective.
- L'étude a identifié 71 gènes DlPP2C dans le longan, avec DlPP2C1 montrant une forte expression régulée par l'ABA, suggérant un rôle dans la signification de l'ABA.
