Objective
Previous investigations suggested that cherry blossoms could provide valuable bioactive materials. However, few observations regarding the anti‐inflammatory effect of cherry blossoms were reported. This study was to explore the anti‐inflammatory effect of cherry blossom extract (CBE), which was used as a soothing ingredient in skincare product.
Methods
In vitro study, the anti‐inflammatory effect of CBE on the nitric oxide (NO) inhibition assay in lipopolysaccharide (LPS)‐treated RAW 264.7 cells was investigated. In vivo study, 40 volunteers were included in a randomized, single‐blinded, placebo‐controlled trial. 24‐hour‐occlusive test chambers were applied on the flexor side of the forearm with 3% sodium lauryl sulphate (SLS). Subsequently, the test areas were treated on 9 subsequent days with a cream containing 3% CBE or a placebo. Evaluation included a visual score and determination of erythema value (E value).
Results
In vitro study, 2% CBE reduced NO production by 31.83% compared to the placebo. In the SLS irritant patch test, the visual score and erythema value of CBE were lower than that of the placebo on D5 and D9.
Conclusion
Cherry blossom extract shows good anti‐inflammatory effect in vitro and in vivo and represents a promising functional ingredient in soothing skincare product by reducing skin inflammation.
Résumé
Contexte
Plusieurs chercheurs ont indiqué que les cerisiers en fleurs pourraient fournir des matériaux bioactifs de grande valeur. Cependant, il y avait peu de rapports concernant l'effet anti‐inflammatoire des cerisiers en fleurs.
Objectif
La présente enquête a été réalisée pour étudier l'effet anti‐inflammatoire de l'extrait de fleur de cerisier (CBE), qui a été utilisé comme un ingrédient apaisant dans les produits de soins de la peau.
Methodes
Dans l’étude in vitro, l'effet anti‐inflammatoire de la CBE sur l'oxyde nitrique (NO) a été étudié dans le test d'inhibition de lipopolysaccharide (LPS) des cellules RAW 264.7 traitées. Dans l’étude in vivo, 40 volontaires ont été inclus dans un protocole en aveugle simple, randomisé, contrôlé contre placebo. Des patchs occlusifs de 24 heures ont été appliqués sur le côté flexion de l'avant‐bras avec 3% de laurylsulfate de sodium (SLS). Par la suite, les zones de test ont été traitées pendant les 9 jours suivants avec une crème contenant 3% de CBE ou un placebo. L’évaluation comprenait un score visuel et la détermination de la valeur d’érythème (valeur E).
