I am using plant extract of Ajuga parviflora and found out that it possess anti-diabetic properties by using alpha-amylase inhibitory assay. I used various concentration 250 µg/ml(29% inhibiton of alpha-amylase), 500µg/ml(37%),750µg/ml(46%) and 1000µg/ml(63%). Basically, alpha-amylase results in increase in glucose level after eating food. So i wanted to know that how could i find out that what is the best concentration of my plant extract to be used as drug.

  • $\begingroup$ This sounds like a homework question. Is it? $\endgroup$ – David Jun 9 '18 at 8:05
  • $\begingroup$ No, i am in my final year of my btech working on a plant and when a plant report some property then it is better if we can also give its best concentration. $\endgroup$ – roxaite Jun 9 '18 at 8:11

You have to try to determine the best concentration.

Usually there are multiple clinical trials, first in animals, then in humans to

  1. figure out the effective dose
  2. look for side effects
  3. compare the new drug's efficacy with existing drugs

  • $\begingroup$ @David Actually I started writing a comment first and was expecting a "please don't answer in comments" response :) And it didn't occur to me this could be homework. $\endgroup$ – Arsak Jun 9 '18 at 8:11
  • $\begingroup$ @David Owh, and the answer was: You have to try. $\endgroup$ – Arsak Jun 9 '18 at 8:14
