Preparation and Establishment of Quality Standard of Weikang Capsule / 中国药房

ABSTRACT

OBJECTIVE:To prepare Weikang capsule and establish its quality standard METHODS:Weikang capsule was prepared with gentamycin sulfate,vitamin B1,vitamin B2,vitamin B6 and vitamin B12 A polarimetry was established for determining the content of gentamycin sulfate in Weikang capsule RESULTS:There was a good linearity between optical rotations and concentrations of gentamycin sulfate from 2 000IU/ml to 12 000IU/ml with a regression equation of ?=0 00 767+1 77 003C,r=0 9 999 The average recovery rate of gentamycin sulfate in Weikang capsule was 100 1%,RSD was 0 79%(n=6) The results of polarimetry and microbioassay were nearly equivalent CONCLUSION:The preparation process of Weikang capsule is simple,and polarimetry for determination of the content of gentamycin sulfate in Weikang capsule wes rapid and reliable
