| Abstract: | A determination method of pharmaceutical polymeric materials was established by designing an orthogonal test.Four important factors and levels of the method were examined by orthogonal testL9(34)].Then the research methodology was done according to Pharmacopoeia of People’s Republic of China 2010.The linear range was from 2 to 100 μg·mL-1(r=0.999 8),the detection limit was 0.5 μg·mL-1,the average recovery was 0.96,intraday RSD was 0.02.The method has met the detection rule of limited impurities according to Pharmacopoeia of People’s Republic of China 2010.It was feasible to measure the level of lactic acid in this kind of PLLA adjuvant. |
| Keywords: | orthogonal test polymeric materials poly L-lactic acid(PLLA) lactic acid |
