R help - Sep 2007 - stastistical test on normalized data

Dear R-maillit,

I have to perform a stastistical test to asses if two grug show the same or
different effect on my prepartion.
I tested on the same preparation only one drug and I have to use normalized data
due to high variability in the control condictions.
What type can I use? 
A non paramatric test right?
And how can do it on R software?
Thanks in advance

Simone

I performed experiments to analyse the effect of 2 different drugs of my 
preparations.
The designs od the experiment is the following:
on 11 preparations I tested the effect of drug 1
and on another 5 preparation I tested the second drug
So the I calculated the % of the effect of the drugs respect to the control 
condictions\
What type of statistical test can I use to verify if the effect of the drug 
is different or not?
Can I use the ANOVA??

These are the data

 

Control  drug 1       

      0.49
     0.29
     
      0.29
     0.08

      0.3
     0.08
     
      0.36
     0.14
     

 

Son the normalized data are
