Abstract

Intracellular pathogens are mainly eliminated by cell-mediated immunity offered by phagocytic cells like neutrophils, macrophages and monocytes. Two tannin glycosides, 1-O-galloyl-6-O-luteoyl-α-D-glucopyranoside (1) and 3-O-methylellagic acid 3'-O-α-rhamnopyranoside (2) were isolated from the ethyl acetate fraction (EF) of the methanol leaf extract of Phyllanthus muellerianus. The structures of the isolated compounds were elucidated by 1H-NMR and by mass spectroscopy. The effects of the isolated compounds on phagocytic competence of macrophages and neutrophils using in vitro models were evaluated. Compounds 1 and 2 significantly (p

江蓠叶提取物中分离的糖苷上调细胞介导的先天免疫

细胞内病原体主要通过吞噬细胞如中性粒细胞、巨噬细胞和单核细胞提供的细胞介导免疫来消除。从余叶甲醇提取物的乙酸乙酯部分(EF)中分离得到1-O没食子酰基-6-O木犀油基-α- d -葡萄糖吡喃苷(1)和3-O甲基鞣花酸3′-O-α-鼠李糖苷(2)两个单宁苷类化合物。分离得到的化合物的结构经1H-NMR和质谱鉴定。用体外模型评价分离化合物对巨噬细胞和中性粒细胞吞噬能力的影响。化合物1和2显著(p
