Application of the method for the quantification of THQ in
various extracts and formulations
The peaks of THQ from sample solution were identified by
comparing their retention times obtained from the peaks with those of
standard. It was observed that there is no any interaction peak of other
constituents or excipients detected at retention time of THQ which
indicated the suitability of this method for the routine analysis of THQ
in marketed formulations (Figure 4). Samples were injected at different
level of dilution and calculated concentration showed good precision.
Amount of THQ obtained in different extracts and formulation are
presented in table 5.
