Ankit Negi

try disc diffusion method or simply dilute sample in ug/ml for better result.

Saif Ali

I diluted the sample but no i did not get result only in 100mg/ml concentration.

Thank you so much Ankit Negi sir i will try disc diffusion method as you suggested me in high concentration to get result

Yoram Gerchman

Pigments are phytochemicals...

You can try and pre-extract (wash) your sample with solvents that will extract the pigments but not your constitute.

Either way 100mg/ml is a very high concentration to begin with. What are you extracting with?
