摘要

为了探究淡竹叶盐成分对脂多糖诱导的RAW264.7细胞炎症抑制作用和肝细胞生长影响,采用竹盐制备工艺制备淡竹叶盐,对比分析粗海盐、精制海盐、传统竹盐和淡竹叶盐的pH、矿物元素含量等理化性质,并探究炎症抑制效果及对不同肝细胞生长的影响。结果表明,淡竹叶盐水溶液呈碱性,矿物元素组成丰富,能显著增强RAW264.7细胞吞噬能力,抑制NO释放以及降低肿瘤坏死因子-α、白细胞介素-1β分泌;显著抑制肝癌细胞(HepG2)的增殖,且淡竹叶盐对HepG2细胞总凋亡率[(45.85±2.93)%]高于传统竹盐[(38.89±2.56)%]、粗海盐[(31.78±4.18)%]和精制海盐[(29.63±1.89)%];而在同质量浓度下,淡竹叶盐对正常肝细胞(WRL68)的凋亡率[(16.98±2.84)%]与竹盐[(15.21±3.10)%]无明显差异,显著低于粗海盐[(22.35±2.24)%]和精制海盐[(19.35±3.12)%],其对正常肝细胞保护作用强于粗海盐和精制海盐。

Abstract

To explore the inhibitory effect of lophatherum gracile salt on LPS induced RAW264.7 cell inflammation and hepatocyte growth, lophatherum gracile salt was firstly prepared using the bamboo salt preparation process. Then the physicochemical properties of crude sea salts, refined sea salt, traditional bamboo salt and lophatherum gracile salt, such as pH and mineral element content, were analyzed. And the inhibitory effect of inflammation and its influence on different hepatocyte growth were explored. The results showed that the salt solution of lophatherum gracile salt was alkaline, which riches in mineral elements. It could significantly enhance the phagocytic capacity of RAW264.7 cells and inhibit the release of NO. Moreover, it also reduced the secretion of TNF-α and IL-1β and inhibited the proliferation of HepG2 hepatoma cells. The total apoptosis rate of HepG2 cells induced by lophatherum gracile salt [(45.85±2.93)%] was higher than that of traditional bamboo salt [(38.89±2.56)%], crude sea salt [(31.78±4.18)%] and refined sea salt [(29.63±1.89)%]. At the same concentration, there was no significant difference between the apoptosis rate of normal hepatocytes [(16.98±2.84)%] and that of bamboo salt [(15.21±3.10)%], which was significantly lower than that of crude sea salt [(22.35±2.24)%] and refined sea salt [(19.35±3.12)%]. Its protective effect on normal hepatocytes was stronger than that of crude sea salt and refined sea salt.

Key words： lophatherum gracile salt; mineral elements; anti-inflammatory activity; proliferation; apoptosis
