Embodiment 1
[0031] Preparation of Compound 1-10:
[0032] Dried seeds (20kg) of Cardamom grassa, crushed, extracted twice with 90% ethanol under reflux, each time for 2 hours, combined ethanol extracts, recovered ethanol under reduced pressure to obtain extract. The extract was dispersed in water and extracted with ethyl acetate, then concentrated to the ethyl acetate extract. Then the ethyl acetate extract (Fr.A, 1.5kg) was subjected to silica gel column chromatography, and methanol-chloroform (0:100, 2:98, 5:95, 10:90, 20:80 and 100:0, v / v) Eight fractions of Fr.A-1 to Fr.A-8 were obtained by gradient elution of the eluent. Fr.A-7 (50g) was obtained by MCI CHP 20P gel column chromatography (methanol-water, 30:70, 40:60, 50:50, 70:30, 100:0, v / v) to obtain Fr.A -7-1~Fr.A-7-6. Fr.A-7-2 (15g) was purified by silica gel column chromatography (MeOH-CHCl 3 , 10:90 and 20:80) obtained Fr.A-7-2a~Fr.A-7-2e. Fr.A-7-2c (5g) was purified by Sephadex LH-20 (chloroform-methanol, 50:50), silica g...
