摘要: 多酚类物质是植物体中重要的次级代谢产物,为充分利用山桐子果实,将果实中多酚类物质提取出来,并对其抗炎、抗菌效果进行研究。利用LSP诱导RAW264.7细胞产生炎症,经不同浓度给药后对MTT、细胞产生NO量进行测定;选取粪肠球菌、枯草芽孢杆菌、鼠伤寒沙门氏菌进行抗菌实验,判断抑菌效果。结果表明:山桐子果实中总多酚含量为6.6 mg·g-1;给药组浓度依次为50、100和200 μg·mL-1,随着给药浓度的增加RAW264.7细胞活力值也在增大,NO释放量随着给药浓度的升高降低,山桐子果实多酚对选取的三种细菌抑菌能力由强到弱为:枯草芽孢杆菌 > 沙门氏菌 > 粪肠球菌。

Abstract: Polyphenols are important secondary metabolites in plant. For full use of the fruit, polyphenols in Ldesia palycarpa Maxim fruit were extracted and the anti-inflammatory activity and antibacterial effect were studied. LSP-induced RAW264.7 inflammatory cells were treated with different concentration polyphenols and the anti-inflammatory effect was determined by MTT assays and NO amount of RAW264.7 cells. Enterococcus faecalis, Bacillus subtilis, Salmonella typhimurium were selected for antimicrobial experiment to analyze antibacterial activity. The content of polyphenols of L.palycarpa Maxim fruit was 6.6 mg·g-1. Under the administration concentrations with 50, 100 and 200 μg·mL-1, along with the increase of administration concentration, RAW264.7 cells viability value was increased and the release of NO from RAW264.7 cells was also decreased. The antibacterial ability of polyphenols in L.palycarpa fruit of selected three kinds of bacteria in the descending order of B.subtilis, S.typhimurium and E.faecalis.

Key words: Idesia polycarpa fruit, polyphenols, anti-inflammatory activity, antibacterial activity
