Soxhlet Extraction: The fresh pulp of C. fistula pod
(10.0 g) was extracted with 300 ml of 70% ethanol in a
soxhlet apparatus. The extraction was continued until
the extraction was exhausted. The extracts were then
combined, filtered and evaporated to dryness on a hot
water bath to yield a soxhlet crude extract (4.3 g).
