out of curiosity, how are you going to use root powder to test? wouldn't you need to dissolve them into something first (i.e water or solvent)??
Hello there
it depends on the assay you are to use ...
i.e in times we use EtOH extracts the others aqueous extracts while the others
we test different organic solvent extracts.
where as the crude one,, i haven't used any ...
as i mentioned before, it depends on the assay.
search for your protocol, am sure you will find the best mode.
Best Wishes,

hi
i am planning to give withania somnifera ( Ashwagandha) root powder suspension in water (with 2% gum acacia) orally to my animal model to test its effect (in vivo). All i was asking, was wheather it is beneficial to start with root powder (crude form) on a new animal model of inflammation/ autoimmune disorder or i should use extracts or individual or combined components present in its roots?

if you have no protocol how to isolate the drug, or if there is no reference to previous work, start to test crude extract AND enriched fractions in various concentrations
reason: if the drug is insoluble or hardly soluble in water or ethanol, you may find results with the crude extract...
