Objective: To optimize the extraction process of volatile oil from Fructus Litseae.Methods: Supercritical CO2 extraction (SFE-CO2) was used to extract volatile oil from Fructus Litseae, and the extraction process was optimized by a central composite design-response surface method (CCD-RSM).The kind and content of volatile oil extracted by SFE-CO2 and steam distillation (SD) were detected by gas chromatography-mass spectrometer (GC-MS).Results: The highest extraction rate of the total effective constituents was 66.26% when the optimum conditions were as follows: the extraction temperature was 44 ℃, the extraction pressure was 26 MPa, entrainer ethanol was 11 ml and the extraction time was 40 min.It was revealed that neral, geranial and limonene were the major constituents.Compared with that of SD, the kind of volatile oil extracted by SFE-CO2 was fewer while the content of citral extracted by SFE-CO2 was higher.Conclusion: The extraction process optimized by CCD-RSM provides reference for the extraction method and quality control of volatile oil from Fructus Litseae.

Objective:To characterize the volatile compounds in 10 batches of disposable infusion sets and 6 batches of nasal can-nulas by GC-MS and determine the main odor-active compounds. Methods:The volatile components were extracted using a headspace sampler. An HP-5MS capillary column (30 m × 0. 25 mm,0. 25 μm) was adopted, and the qualitative analysis was performed by total ion chromatography ( TIC) of full scan with temperature programmer. Results:A total of 19 major volatile compounds were identified, which were hydrocarbon, alcohol and carbonyl compounds (such as aldehyde and ester). Based on the combination of odor test and GC-MS, the concentration of alcohol compounds (2-ethyl hexanol, 2-EH) had the most notable effect on the odor of samples. Conclu-sion:The samples with unacceptable order contain 2-EH with relatively high content, which should be paid more attention.

Objective To establish a CVS-11 pseudovirus particles ( pp)-based assay for detec-tion of neutralizing antibody against rabies virus. Methods An improved rapid fluorescence focus inhibition test ( RFFIT) for detection of neutralizing antibody against rabies virus ( RVNA) was established based on the CVS-11 pseudovirus expressing a luciferase reporter gene. Forty-six human serum samples were analyzed with the improved RFFIT and the results were compared with those by using standard RFFIT. Moreover, the improved RFFIT was used to detect the titers of RVNA in 91 serum samples collected from pet dogs and pet-breeders in Beijing. Results The coincidence rate of the improved RFFIT and the standard RFFIT was 100% regarding to the analysis of 46 human serum samples and 5 negative reference serum samples. Moreo-ver, the RVNA titers of all serum samples obtained with CVS-11 pseudovirus-based assay showed a signifi-cant high correlation with those obtained with standard RFFIT (n=46, r=0. 94, P<0. 000 1). All of the 91 serum samples collected from pet dogs and pet-breeders in Beijing were positive for RVNA as indicated by the improved RFFIT with a mean titer of 33. 01 IU/ml. Conclusion We established an improved RFFIT based on the CVS-11 pp expressing luciferase reporter gene, which might be used as a reliable alternative RFFIT for measuring RVNA titer. Analysis of the 91 serum samples collected in Beijing with the improved RFFIT showed that all samples were positive for RVNA.
