if the plant extract gives effect
as much does not isolate the material responsible for this effect??
there is a large number of researches that are limited to the extract only
DEAR Bendaif Hajar ,
You should search about the active constituents in your plant extract and you can detect the specific compound which have the effect on the target by purification ?
Best regards
If you determine the effective plant extract, you do biofractionation against a certain pest. After you identify the effective fractions of the extract, you can either isolate the actine principle or analyze the acitve fraction to know its consistuents.
Thank's a lot of for your answers
Purification is important,but sometimes we need a new ideas for purification, some people search the exract effect not the moecule effect
