制备方法与用途

背景

鸡屎藤为茜草科鸡矢藤属多年生草质藤本植物鸡矢藤的全草及根，具有祛风除湿，消食化积，解毒消肿，活血止痛的功效。单独使用鸡矢藤甙(paederoside)，具有较好的镇痛抗炎效果。鸡矢藤甙具有良好的外周镇痛效果和中枢神经镇痛效果，同时还具有良好的抗炎效果，因此，可单独或与药学上可接受的其它成分共同使用，制备止痛药物和抗炎药物。

应用

鸡矢藤甙具有良好的外周镇痛效果和中枢神经镇痛效果，同时还具有良好的抗炎效果，因此，可单独或与药学上可接受的其它成分共同使用，制备止痛药物和/或抗炎药物。

制备

一、一种鸡矢藤甙的制备方法，其特征在于包含以下步骤：

1）提取：取鸡屎藤药材粉碎，加入8-12倍量蒸馏水微波萃取2-3次，每次0.5-2h，过滤，得到提取液；

2）大孔树脂吸附：将上述提取液加入大孔树脂柱吸附，先用蒸馏水洗脱至下柱液无色，再用40-60%乙醇溶液洗脱，得到洗脱液；

3）聚酰胺分离：将上述洗脱液浓缩至无醇味，加入聚酰胺柱，依次用蒸馏水和30%乙醇洗脱，收集洗脱液；

4）重结晶：将上述洗脱液浓缩至小体积，放置结晶，滤出结晶，用乙醇回流溶解，滴加石油醚重结晶，滤出真空低温干燥即得鸡矢藤甙。

化学性质 

黄色粉末，可溶于甲醇、乙醇、DMSO等有机溶剂，来源于鸡屎藤Paederia scandense。

• Iridoid glucosides from roots of Vietnamese Paederia scandens
  作者：D Quang

  日期：2002.7

  Four iridoid glucosides, three of which are dimeric were isolated from the methanol extract of roots of Vietnamese Paederia scandens (Lour) Merrill together with the five known glucosides, paederoside, asperuloside, paederosidic acid, asperulosidic acid and geniposide. Seven sulfur-containing iridoid glucosides were also isolated. The structures of the iridoid glucosides were determined by a combination of high-resolution NMR, MS, IR and UV spectra, and chemical reaction such as acetylation. (C) 2002 Elsevier Science Ltd.
