Oleoresin was extracted in a Soxhlet’s apparatus using solvent
acetone. 5.0 g dry material was loaded in glass columns blocked
with non-absorbent cotton. Acetone (15 ml) was allowed to percolate down into the glass column and kept in and the contact was
maintained for overnight. Soluble extracts were then drained off
into a pre weighed 100 ml beaker.
