title: [Determination of elemenyl piperidine salt in water by capillary gas chromatography].
abstract: beta-Elemene and its derivatives were hopeful new antitumor drugs. A method for determination of elemenyl piperidine salt in water has been developed with capillary gas chromatography. The samples were neutralized by sodium carbonate and extracted by n-heptane. n-Octadecane was used as the internal standard. The linear range was from 10 g/L to 100 g/L, with a correlation coefficient of 0.9998. The average recovery of the method was 99.96% and the RSD was 0.46% (n = 5). The coefficient of variation was less than 2%. The method is simple, rapid, accurate and can be applied to the determination of the nitrogen-containing compounds of beta-elemene.
