OBJECTIVE: To establish a method of GC-Second Order Temperature Programming for determining the residual quantities of 4 organic solvents-methanol, acetonitrile, pyridine and dimethylformamide-in Methylprednisolone Sodium Succinate. METHODS: The separation was performed on DB-5 capillary column, with flame ion monitor as detector, and with high pure nitrogen, air and hydrogen as carrier gas. The column temperature was subjected to GC-Second Order Temperature Programming, with the temperature of sample injector at 200℃ and that of detector at 220℃. The make-up gas was high pure nitrogen. The split ratio was 10∶1. The sample size was 2?L and the butanone was taken as the internal standard. RESULTS: The four kinds of solvents were linear within their respective concentration range. The average recoveries of methanol, acetonitrile, pyridine and dimethylformamide were 99.4%, 99.2%, 99.3% and 99.0%, respectively, with RSD at 1.8%, 1.8%, 2.0% and 1.7%, respectively. CONCLUSION: The method was proved to be sensitive, accurate and simple.

7.In Vitro Study on the Transdermal Permeation Enhancing Effect of N-trimethyl Chitosan on Estradiol Gels
China Pharmacy 2001;0(07):-
OBJECTIVE: To study the enhancing effect of N-trimethyl chitosan with degree of quaternization of 60% (TMC60) on the estradiol gel in vitro. METHODS: TMC60 was synthesized and the degree of quaternization was determined by 1H-NMR. Three different kinds of estradiol gels, 2% TMC60 group, 2% azone group and blank control group, were studied respectively. The cumulative penetration Q and steady penetration rate J in vitro were used as the indices. The cumulative penetration was calculated. RESULTS: The degree of quaternization of TMC60 was 67.2%. Significant difference was found the value Q and J of TMC60 group when compared to blank control group(P0.05). CONCLUSION: 2% TMC60 is a penetration enhancer with similar enhancing effect as 2% Azone, which deserves further research.

OBJECTIVE: To develop a method of HPLC/MS/MS to determine phenacetin and paracetamol in rat liver microsomal incubation system. METHODS: Samples were separated on XTerra MS C18 column, different ratios of methanol- 0.1% formic acid were used as the gradient eluent, and the flow rate was 0.2mL?min-1. The electrospray ion-quadrupole mass spectrometry and multiple reaction monitor were adopted to detect the concentration of phenacetin and paracetamol. RESULTS: The calibration curves were linear in the ranges of 45~9 000ng?mL-1(r=0.999 8)and 15.2~1 520ng?mL-1(r=0.999 6) for phenacetin and paracetamol respectively; The lowest limits of assay were 9ng?mL-1 and 10ng?mL-1.The average recoveries at three concentrations of phenacetin were (96.2?2.3)%~(98.3?2.4)% and those of paracetamol were (99.6?2.1)%~(100.2?2.6)%; RSD of the intra-day and inter-day were less than 5%.
