The use of principal component analysis and self-organizing map to monitor inhibition of calcium oxalate crystal growth by Orthosiphon stamineus extract
S Dharmaraj, MA Hossain, S Zhari, GL Harn… - … and Intelligent Laboratory …, 2006 - Elsevier
The modified Schneider's gel slide method is used to monitor the inhibitory effect of 50%
methanol extract of Orthosiphon stamineus on the growth of calcium oxalate crystals. The
images of crystals grown in the gel were captured at 1, 2, 3, 4 and 24 h with digital camera
and image analysis was carried out. A total of nine variables relating to size and shape
parameters were calculated and six were used for further analysis. Principal component
analysis (PCA) and self-organizing map (SOM) were applied in the visualization of the size …
