【摘要】 从萆廣中分离出一种白色针状结晶，经ＴＬＣ和ＭＰ鉴定为薯蓣皂甙。萆薢粉经乙醇提取后制成水剂，比色法测定薯蓣皂甙质量浓度为４．７８５ ７ ｇ·Ｌ－ １．将３０ 只痛风鸡随机分成３ 组，每组１０ 只，第Ⅰ组为对照；第Ⅱ组每日用肾肿清按１０ ｇ·ｋｇ－ １的比例拌料饲喂；第Ⅲ组每日饮水中添加５２．５ ｍ Ｌ皂甙水剂。每间隔３ ｄ 颈静脉采血３～５ ｍ Ｌ／只，分别测定血液尿酸、血清钙、血清磷的含量。结果表明，第Ⅱ，Ⅲ组血液尿酸含量比第Ⅰ组明显降低，差异显著（Ｐ＜ ０．０５）；第Ⅱ，Ⅲ组血清钙和血清磷含量与第Ⅰ组差异不显著（Ｐ＞ ０．０５）；第Ⅱ组血液尿酸、血清钙和血清磷含量与第Ⅲ组差异不显著（Ｐ＞ ０．０５）。第Ⅱ组和第Ⅲ组治愈率分别为６０％ 和８０％ ．更多还原

【Abstract】 Dioscin,a white needle crystal isolated from Rhizoma Dioscoreae colletii,was identified by TLC and MP.The powder of Rhizoma Dioscoreae colletii was extracted with 800 mL/L ethanol to prepare water agent of dioscin with the content of dioscin being 4.785 7 g·L -1 .30 chicks were divided into 3 groups randomly,10 chicks in each group.Group Ⅰ was control,Group Ⅱ was fed with forage containing 1 percent Shenzhongqing each day and Group Ⅲ added 52.5 mL prepared water agent in drink water each day.Blood samples (3～5 mL/chick) were collected from jugular vein with an interval of 3 days.The contents of uric acid,serum calcium and phosphorus were determined.The results revealed that the contents of uric acid in groups Ⅱ and Ⅲ were significantly lower than Group Ⅰ ( P <0.05),but there was no significant difference between groups Ⅱ and Ⅲ ( P >0.05).The contents of serum calcium and phosphorus were noticed in Group Ⅱ.There was no significant difference among three groups ( P > 0.05) .The cure rates of group Ⅱ and Ⅲ were 60 percent and 80 percent,respectively.更多还原
