Simultaneous Determination of Six Active Constituents in Shexiang Baoxin Pills by GC-MS / 中国药师

ABSTRACT

Objective: To develop a GC-MS method for the simultaneous determination of six active constituents ( borneol, isoborneol, cinnamaldehyde, cinnamic acid, muscone and benzyl benzoate) in Shexiang Baoxin pills. Methods: A gas chromatogra-phy-mass spectrography (GC-MS) method was adopted using a DB-5 capillary column (30 m × 0. 25 mm,0. 1 μm). The column tem-perature was raised as the following programthe initial temperature was 70℃, maintained for 2 min, raised the temperature (5℃· min-1) to 150℃, maintained for 4 min and then raised the temperature (20℃·min-1) to 260℃, and maintained for 3 min. The range of mass-to-electric charge ratio was 10 to 425. Results:The calibration curves of borneol, isoborneol, cinnamaldehyde, cinnam-ic acid, muscone and benzyl benzoate were linear within the range of 0.022-22.000 μg·ml-1(r=0.999 6),0.024-24.000 μg· ml-1(r=0.999 6),0.028-28.000μg·ml-1(r=0.999 8),0.034-34.000μg·ml-1(r=0.999 6),0.040-40.000μg·ml-1(r=0.999 7) and 0.050-50. 000 μg·ml-1 (r =0.999 9), respectively. The average recovery was 97.20%, 97.40%, 97.53%, 99. 60%, 98. 78% and 98. 27% and RSD was 0. 89%, 1. 18%, 1. 52%, 1. 49%, 0. 79% and 1. 74%(n=6), respectively. Con-clusionThe method is accurate, suitable, convenient and reproducible, which can be used for the quality control of multi components in Shexiang Baoxin pills.
