Peumus boldus Extract Inhibits Lipid Accumulation in 3T3-L1 Adipocytes

Year: 2025

Type: article

Abstract: Obesity is a metabolic condition of epidemic scale. Previously, we showed that antioxidant extracts from Ribes nigrum had antioxidant and anti-adipogenic effects in mature adipocytes (AD). Here, we evaluated an aqueous extract from Peumus boldus (Boldo) in AD and studied its effect on reactive oxygen species (ROS) and lipid production. We analyzed the antioxidant activity (AA) of the Boldo extract using the DPPH technique and polyphenol (Pph) content via Folin’s reagent. In AD, we evaluated ROS production, catalase (CAT) activity, intracellular triglyceride (Tg) and cholesterol (Chol) contents, nitric oxide (NO) production via Griess reagent, and the levels of glycerol (Gly) and TNF-α released in the culture medium. We showed that the Boldo extract has high AA. In vitro, Boldo treatment decreased ROS intracellular production and CAT activity. In addition, the Boldo extract was effective in reducing Tg and Chol levels and NO production. We did not identify significant differences in Gly released or TNF-α secreted. We suggest that the Boldo extract has antioxidant and anti-adipogenic effects, but we did not observe lipolytic effects. Boldo did not modify inflammatory markers.
