摘要: 本研究旨在建立一种新的广地龙提取方法,并对其抗氧化和抗炎活性进行检测。利用无水乙醇对鲜地龙进行提取,采用无水乙醇浸渍粗提、MCI柱初步纯化、葡聚糖凝胶LH-20纯化、以及索氏提取法脱色除臭等方法,得到地龙醇提取物13.6 g,产率较高,为63.3%。同时,薄层色谱法检测结果显示地龙乙醇提取物含有丰富的具有荧光特性的小分子化合物,且具有DPPH自由基、羟基自由基和超氧阴离子清除活性,有较高的A375人黑色素瘤细胞抑制活性,对巨噬细胞没有显著的细胞毒,但对NO有较强抑制活性。因此,该制备方法分离效果佳、操作方便、得到的地龙提取物在抗氧化、抗黑色素瘤细胞以及抗炎等方面具有较强活性且质量稳定。

Abstract:

The aim of this study is to establish a new extraction method from Pheretima aspergillum,and to investigate its antioxidant and anti-inflammatory activities.The crude was extracted from fresh Pheretima aspergillum by absolute ethanol,purified by MCI column and Sephadex gel LH-20,and Soxhlet extraction was used to decolorization and deodorization.The results showed that the ethanol extract of Pheretima aspergillum obtained in our study was 13.6 g,and the yield was 63.3%,which was the highest yield obtained.TLC results showed that the ethanol extract of Pheretima aspergillum was rich in small molecular compounds with fluorescent properties,and had DPPH free radical,hydroxyl free radical and superoxide anion scavenging activity.It also had higher inhibitory activity on A375 human melanoma cells,and had no significant cytotoxicity on macrophages,but had stronger inhibitory activity on nitric oxide (NO) production.The new extracting method has better separation effect,more convenient operation and higher yield,and the ethanol extract has significant antioxidant,anti-melanoma cells and anti-inflammatory activities.

Key words: Pheretima aspergillum, extract, antioxidant activity, anti-inflammatory activity
