washeated in a hot air oven at 100оC for 60 min, and then TSH(28 g) was obtained by careful separation. The brown-red
seed husk was collected and ground into fine powder, part of which (10 g) was extracted with 150 mL of
ethanol/water (3:2, v/v) at 60оC for 24 h. The insoluble materials were removed by filtration. Crude TSE (4.5 g)
was obtained by lyophilizing the extracted solution after removing ethanol under reduced pressure at 60-70°C.
Extraction three times in the same manner was carried out to compare with one pot extraction.
