| Abstract: | Objective：To determine the content of nicotinic acid micropellets.Methods：Centrifugal granulation method was used to prepare nicotinic acid micropellets,the nicotinic acid was determined by UV method.Results：Nicotinic acid showed good linear correlation within a concentration range of 2.0~20.0 μg·mL-1 with RSD%〈2%.Average recovery rate was 98.5%,and the content of nicotine acid micropellets was 70.6 %.Conclusion：The UV Spectrophotometry used for determining the content of nicotinic acid micropellets yielded was accurate,simple,quick and reproducible. |
