2.5. Method validation
Linearity graph, precision viz. intraday and interday
variations, limit of detection and limit of quantification,
accuracy (% recovery) and analysis of aloeverose in prepared
formulations were carried out as a part of method validation
using ICH guidelines. Limit of detection and limit of
quantification were estimated on a statistical evaluation
base for six determinations of the samples using ICH guidelines.
The accuracy of the method was tested by performing
recovery at three levels. Approximately 50%, 100% and 150%
of the determined content of aloeverose in A. vera gel were
spotted in triplicate on the plate. Chromatograms were
developed, scanned, their peak areas recorded and the
percent recovery was calculated.
