Anti-Inflammatory and Neuroprotective Effects of Standardized Fractions in Herniarin and Daphnoretin from Distictis buccinatoria

Distictis buccinatoria is used for inflammatory-related diseases. From a dichloromethane extract were obtained five different fractions called F1 to F5, and sub-fractions F4-1, F5-1, F5-2, and F5-3; and were evaluated as anti-neuroinflammatory, antioxidant, and nootropic agents in mice exposed to lipopolysaccharide. Also, were isolated herniarin, daphnoretin, and fraction's terpenes with an anti-inflammatory activity using 12-O-tetradecanoylphorbol-13-acetate-induced auricular edema. The inhibition of local edema was: F1 (73.6 %), F2 (57 %), F3 (62.61 %), F4 (87.3 %), and F5 (93.57 %). Terpene fraction inhibited at 89.60 %, herniarin at 86.92 % (Emax 99.01 %, ED50 0.35 mg ear⁻¹), and daphnoretin at 86.41 %. Fractions F4-1 and F5-2 (10 mg kg⁻¹) enhancer spatial memory acquisition and spontaneous motor activity; reduced IL-1β, TNF-α, and IL-6; increased IL-10, enhanced the activity of CAT and GR. D. buccinatoria has neuroprotective activity and contains daphnoretin and herniarin, with anti-inflammatory activity.
