罗布麻Ⅰ、Ⅱ（简称ＬⅠ、ＬⅡ）分别采集于山东省２个产地，罗布麻Ⅲ、Ⅳ（简称ＬⅢ、ＬⅣ）分别是ＬⅡ烘干１次及２次之后而得。将４组样品分别于７０℃热水中提取３ｈ，过滤，减压蒸发，得提取物。实验选用雄性Ｗｉｓｔａｒ大鼠，造模，给予ＬⅠ～ＬⅣ水溶液。结果：高胆固 Apocynum I and II (abbreviated as LI and LII) were collected from two production sites in Shandong Province. Apocynum III and IV (abbreviated as LIII and LIV) were obtained after LII was dried once and twice. Four groups of samples were extracted in hot water at 70° C. for 3 h, filtered, and evaporated under reduced pressure to obtain the extract. Male Wistar rats were used in the experiment to make models and give LI-LIV aqueous solution. Result: high gall
