It may help to get an answer if you list what method are you using to extract.

dear sir, i am using 30% ethanol for extraction and time is 3 hours. after that i found considerable suspension in the liquid which is hard to remove

Hi,

if your extract in suspension form then try to centrifuge at high speed (3000-7000 rpm) for 20-30 min and later supernatant filter with whatmann filter paper and finally your extract filter with 0.2 micron syringe filter.

I hope this information may help for your research.

Have a good time.

Hi,

Try your extract pass through hyflow bed. it is simple and good efficient for large volumes.

all the best
