Embodiment 1
[0058] Embodiment 1: Take 5 kg of Luoguo bottom in Qiaojia County, Yunnan, grind it into medium powder, put it into a seepage container, add 24 times the amount of acetone to soak for 48 hours at 15-25 ° C, and then carry out percolation according to the Chinese Pharmacopoeia percolation method , recover the percolation liquid, mix the extract with an equal amount of silica gel, dry at 50-70°C, put it on a silica gel column, use chloroform: methanol as the eluent for gradient elution, and collect the eluate at a concentration of 3-5% methanol After recovery, the crude product can be obtained, and recrystallized several times with methanol to obtain columnar crystals with a melting point of 226-228°C and a purity of 98.98% by HPLC analysis. As shown in Figure 1, it was confirmed to be bilbacetin by four-spectrum analysis of ultraviolet, infrared, nuclear magnetic resonance and mass spectrometry.
