摘要
目的：研究左金缓释片释放规律及评价方法。方法：采用总量统计矩相似度法评价左金缓释片体外溶出液指纹图谱的相似性。结果：于1h至12h不同时间点所获左金缓释片溶出液指纹图谱的零阶矩、一阶矩、二阶矩的平均值分别为：2．620×10^8μv·sec、74．599min、252．481min。；RSD分别为62．445％、1．268％、2．777％。与全溶样品指纹图谱相比，各时问点溶出指纹图谱相似度的最小至最大值为0．947～0．991，平均值为0．977，RSD为1．491％。结论：总量统计矩相似度法能评价中药控缓释制剂多成分整体溶出规律，控制其质量。
AIM： To study and evaluate release rules of Zuojin Sustained-Release Tablet（ZJSRT）. METHODS： The total quantum statistical moment similarity （TQSMS）was used to evaluate similarity of the chromato- graphic fingerprints of ZJSRT in vitro dissolution; RESULTS： Compared with the chromatographic fingerprint of the complete dissolution sample , the averages of area under curve of total quantum, mean chromatographic retention time of total quantum and variance of mean chromatographic retention time of total quantum of the ZJSRT＇ s release rules in vitro, from 1 to 12 h, were 2. 620 × 10^8 μv · see, 74. 599 rain and 252. 481 min^2 respectively, meanwhile their RSD were 62. 445% 、 1. 268% and 2. 777% coincidently, the similarities range from 0. 947 to 0. 991 ,as average of 0. 977 and RSD of 1. 491%. CONCLUSION： It is suggested that the TQSMS can evaluate release rules of muhieompon and control its quality.
