Determination of Residual Organic Solvents in Lovastatin by Headspace Gas Chromatography
摘要
Abstract
OBJECTIVE: To establish a method for the content determination of residual organic solvents in lovastatin, i.e.alcohol, acetone, ethyl acetate and methylbenzene.METHODS: Headspace GC was adopted.The determination were separated on DB-624 capillary column using temperature programming.FID was used as detector with a temperature of 280 ℃, and the inlet temperature was 160 ℃.RESULTS: The linear ranges of alcohol, acetone, ethyl acetate and methylbenzene were 10.0~250 μg· mL-1 (r=l.000 0), 10.0~2550 μg·mL-1 (r=0.999 9), 10.0~250 μg·mL-1 (r=0.999 9), 1.78~89 μg·mL-1 (r=0.999 7), respectively.The average recoveries ranged from 97.6% to 99.1% with RSD of 0.9%~1.9%.The determination limits were 0.22~ 5.61 μg·mL-1.The residual levels for the 4 organic solvents in 4 batches of samples were all up to the standard stipulated in Chinese Pharmacopeia (2005 edition).CONCLUSION: The method is simple, precise, accurate and reliable.关键词
