Recently, many investigators have initiated searches for anti-inflammatory substances from natural resources because of an increasing trend in various inflammatory diseases. The pine (Pinus densiflora) is one of the popular plant drugs which have been used as a medicine in Asia.
Therefore, we studied anti-inflammatory activity of ethanol extracts from different parts of pine in LPS-stimulated murine macrophages. As a result, nitric oxide (NO) production of pine pollen (PP) and pine needle (PN) ethanol extracts was lower than the control at a concentration of
50 μg/mL, while NO production of pine gnarl (PG) ethanol extracts made no considerable differences. Also, TNF-α, IL-6 and IL-1β levels decreased in PP, PE and PG ethanol extracts at the concentration of 1-50 μg/mL. Especially, PE ethanol extracts showed the lowest TNF-α,
IL-6 and IL-1β levels at a concentration of 50 μg/mL. In conclusion, it is demonstrated that PP, PE and PG ethanol extracts have anti-inflammatory activity in LPS-stimulated murine macrophages.
