Embodiment 1
[0026] Compound 1-6 separation and purification:
[0027] Partial extraction and separation from ethyl acetate of Gastrodia elata. Fresh Gastrodia elata (45.0kg) slices were soaked in 90% ethanol for three times, filtered, the residue was soaked in 50% ethanol for three times and filtered, the residue was boiled once, all the filtrates were combined, and concentrated under reduced pressure until alcohol-free. Extract with ethyl acetate 3 times, obtain ethyl acetate extraction part (102g), water phase is through macroporous resin, water, 50% ethanol and 90% elution respectively, obtain water part (1.6kg), 50% ethanol (71g ), 90% (8g). Mix 88g of sample with 88g of silica gel, and use 880g of silica gel for wet packing. with EtOAc:CHCl 3 The system was eluted at 0:100, 5:95, 10:90, 20:80, 40:60, and MeOH, and 5 fractions were obtained. Guided by activity tracking, the active part and the inactive part were separated and purified, as shown in the table 2 is the test results o...
