摘要:

基于脂多糖(lipopolysaccharide, LPS)诱导的RAW264.7细胞模型研究陈皮精油抗炎作用。通过Griess法检测一氧化氮(nitric oxide, NO)分泌水平, 采用Real-time PCR法检测细胞中肿瘤坏死因子(tumor necrosis factor α, TNF-α)、白细胞介素6(interleukin-6, IL-6)、白细胞介素1β(interleukin-1β, IL-1β)和诱导型一氧化氮合酶(inducible nitric oxide synthase, iNOS)、环氧化酶2(cyclooxygenase 2, COX-2) mRNA的表达水平。结果显示, 陈皮精油显著降低LPS诱导的RAW264.7细胞释放NO的含量, 抑制iNOS、COX-2、IL-1β、IL-6和TNF-α mRNA的表达。综上所述, 陈皮精油通过抑制炎症因子的分泌和表达, 有效缓解由LPS诱导RAW264.7细胞炎症反应。

Abstract:

The anti-inflammatory effect of essential oils from Citrus reticulata Blanco was investigated based on lipopolysaccharide (LPS)-induced RAW264.7 cell model. The level of Nitric oxide (NO) secretion was detected by Griess method, and the mRNA expression levels of tumor necrosis factor (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2) were determined by real-time PCR method. The results showed that essential oils from Citrus reticulata Blanco significantly decreased the level of NO released from LPS-induced RAW264.7 cells and inhibited the expression of iNOS, COX-2, IL-1β, IL-6 and TNF-α mRNA. In conclusion, essential oils from Citrus reticulata Blanco can inhibit the secretion and expression of inflammatory factors, and thus alleviate the inflammatory response induced by LPS in RAW264.7 cells effectively.

Key words: Citrus reticulata Blanco, essential oils, anti-inflammatory, LPS, RAW264.7 cell
