考察市售不同厂家生产的双黄连口服液的质量控制。依据2015版《中国兽药典》二部双黄连口服液质量标准~([1]),采用薄层色谱法和高效液相色谱法,分析双黄连口服液中的黄芩苷、绿原酸和连翘苷的色谱特征和含量。结果表明,测定18批双黄连口服液的合格率为33.33%:而定性检测合格的比例为66.67%;黄芩苷含量范围为0.17%～439.61%,黄芩苷含量合格率为61.11%;绿原酸含量范围为0.02%～231.48%,绿原酸含量合格率为33.33%;连翘苷含量范围为0.46%～341.87%,连翘苷含量合格率为38.89%。源于18个厂家的双黄连口服液的合格率仅为33.33%,且双黄连口服液中主要成分含量相差较大,因此,应从中药材的源头控制及制剂生产环节全过程进行产品质量控制,确保产品质量稳定可控。 相似文献

消食平胃散中厚朴薄层鉴别方法研究 总被引：1，自引：0，他引：1
消食平胃散是《中华人民共和国兽药典》二部（以下简称《中国兽药典》）收载的成方制剂。通过对方中厚朴的薄层鉴别方法的研究,认为《中国兽药典》2005年版消食平胃散中厚朴的鉴别方法有值得商榷之处,改用《中国兽药典》2005年版厚朴药材中的鉴别方法更为可行。 相似文献

为了提高和完善《中华人民共和国兽药典》二○一○年版中四黄止痢颗粒的质量标准,改进四黄止痢颗粒项下黄连、黄柏的薄层鉴别方法,增加黄芩的定性鉴别。采用HPLC法测定黄芩苷含量。薄层色谱斑点清晰,阴性无干扰。黄芩苷对照品浓度在3.122~124.88μg/m L(r=0.9991,n=6)范围内与峰面积呈良好的线性关系;平均加样回收率为101.4%,RSD为1.6%。该方法简便、准确、重现性好、精密度高,可作为四黄止痢颗粒的质量控制方法。 相似文献

在现代法律秩序中,商会自治规范是制定法的基础和必要的补充,甚至在某些方面替代了制定法;商会自治规范主要包括商会组织规范、行为规范、惩罚规范以及争端解决规范等;其效力仅及于其内部成员;商会自治规范和制定法之间存在冲突,但也存在整合的基础。 相似文献

以国际标准强毒Ｒ株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离ＭＧ,并收集感染鸡所产蛋分离ＭＧ。结果表明,人工感染４８小时后上、下呼吸道及肺已被全面感染,９６小时气囊已被感染,１２０小时输卵管已能分离到ＭＧ,卵巢始终分离不到ＭＧ。人工感染鸡自１４４小时便能在其所产蛋中分离出ＭＧ。药物治疗能在７２小时内消除感染,油乳剂苗则需２４天后逐渐降低蛋内ＭＧ分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内ＭＧ,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献
