Article Snippet: New Zealand , -CAPE -Pinobanksin -Pinobanksin-3-O-acetate -Pinocembrin -Chrysin -Galangin , Model: Human gastric cancer cells NCI-N87 (ATCC CRL-5822). Protocol: Production of different types of propolis-cyclodextrin complexes: CD1, CD2, CD3, CD4 and CD5. In vitro cytotoxic activity was assessed by the MTT method. Activated neutrophil anti-inflammatory assays. Lipid antioxidant assay. Positive control 5-FU tested at 15 ng/mL. Compounds reported in propolis were given by the manufacturer of this sample. , -Cytotoxic activity: Propolis complexes had moderate cytotoxic activity since CD3 inhibited NCI-N87 cells by 32.7%, CD4 by 24.6%, and CD5 by 21.8% at 200 μg/mL. Pinocembrin had 72.5% cytotoxic activity at 200 μg/mL. -Anti-inflammatory activity: At 50 μg/mL, New Zealand propolis (alone) inhibited TNF-α by 85% ± 1, CD1 by 93% ± 1, and CD2 by 97% ± 1. At 200 μg/mL, all three samples inhibited this cytokine by 100%. -Lipid antioxidant activity: The five propolis complexes and CAPE (also in the γ-CD complex) had moderate antioxidant activity. CAPE (alone) showed strong antioxidant activity. , [ ] .
