RESUMO
[Objectivej To establish a gas chromatography (GC) method for the determination of the content of camphor, isoborneol and borneol in Anmo Ointment. [ Methods ] The determination was performed by programmed temperature GC, in which a 100% concentration of dimethylpolysiloxane was used as stationary liquid phase and the GC was equipped with FID detector at 300℃. [Results] The isolation and the linearity were fine with the rate of recovery of camphor 100.5% (RSD being 1.4%), isoborneol 99.1% (RSD being 1.8%) and borneol 100.8% (RSD being 1.3%). [Conclusion] This method is sensitive, rapid and accurate. It can be used to control the quality of Anmo Ointment.
RESUMO
A specific and sensitive GC - MS method for assaying Borneol in the serum of rats medicated orally with compound Danshen dropping pill was developed. Naphthalene was used as the internal standard, the dectection was performed by SIM. The calibration curve was linear in the range from 0.00505 to 40. 1 ?g/mL, the detectable limit of this method was 1 ng/mL. The extraction recovery of Borneol was 72.82% - 86.77%. The RSD of within - day and day - to - day was less than 2.76% and 1.93% respectively. The results showed that this method was simple, sensitive, accurate and good reproducibility , and can be used in further pharmacokinetic study of Borneol in danshen Dropping pill.
