ABSTRACT
OBJECTIVE:To study the quality standards for Shenchang injection.METHODS:TLC was applied to identify the properties of Borneol and volatile oil of Rhizoma Acori Tatarinowii in the formula.HPLC was adopted to determine the content of ?-asarone in Shenchang injection.RESULTS:?-asarone showed good linear relationship in the range of 0.632 3～ 1.264 6? g.The average recovery of ammonium ?-asarone was 99.92%(RSD=0.91%).CONCLUSION:The standard can be used for the quality control of Shenchang injection.
ABSTRACT
Objective To analyze what will create after oxidation in Shenchang Injection, the oxidated mechanism, and isomerous conversion of ?-asarone and borneol in it. Methods To analyze the sample of Shenchang Injection before and after oxidation by GC-MS and to compare the composition of ?-asarone and borneol before and after sterilization. Results Some of ?-asarone was oxidized and changed to asarylaldehyde (about 0.88%—2.82% of total composition ) and saishinone (about 0.24%—0.46% of total composition), some of the borneol and isoborneol was oxidized and changed to camphor when three samples of Shenchang Injection are oxidized; some of ?-asarone (cis-) change to ?-asarone (trans-, about 1%—2%), (7.85?7.27)% of the isoborneol (cis-) changed to borneol (trans-) when sterilized at 100 ℃ for 30 min. Conclusion ?-Asarone and borneol in Shenchang Injection are involved in the oxidated reaction and have isomerous conversion after high pressure sterilization.
