The maximum recoverable aloin was estimated by Soxhelt extraction using methanol. 5 % (w/w) dry gel particles of
size 0.42 – 0.841 mm were taken in Soxhelt with 200 ml methanol. Extraction was carried out for 24 hours. Samples free
from dry gel were collected, stored in a freezer, and analyzed using HPLC to determine the concentration of aloin
