Anti-Inflammatory Activity-Guided Isolation and In Silico Validation of Turmeric (<i>Curcuma longa</i> L.) Phytochemicals.

ABSTRACT: Turmeric (Curcuma longa L., Zingiberaceae) is a widely consumed spice and functional food valued for its bioactive constituents. Using an activity-guided strategy, this study identified the dichloromethane fraction as the most potent anti-inflammatory fraction, exhibiting markedly stronger inhibition of reactive oxygen species (ROS) production than ibuprofen (IC₅₀ ≤ 0.4 vs. 11.2 μg/mL). Bioassay-guided purification yielded bisacurone (1), didemethoxycurcumin (2), and β-turmerone (3), with compounds 1 and 2 reported here for the first time in this fraction. Among them, β-turmerone displayed the strongest anti-inflammatory activity (IC₅₀ = 4.7 μg/mL), consistent with in silico docking and molecular dynamics analyses, revealing g
