Embodiment 1
[0038] A method for preparing and purifying perchlorate of total alkaloids of lotus heart, which is characterized in that, taking 1 part of total alkaloids of lotus heart powder, adding an appropriate amount of commercially available perchloric acid to completely dissolve it, and then adding an appropriate amount of purified water to dilute to perchloric acid With a mass concentration of 10%, add 1.5 times the volume of water-saturated dichloromethane to extract twice, combine the dichloromethane, recover, concentrate, and dry to obtain total alkaloid perchlorate 1 of lotus root.
Embodiment 2
[0040] A method for preparing and purifying perchlorate of total alkaloids of lotus heart, which is characterized in that, taking 1 part of total alkaloids of lotus heart powder, adding an appropriate amount of commercially available perchloric acid to completely dissolve it, and then adding an appropriate amount of purified water to dilute to perchloric acid The mass concentration is 1%, add 3 times the volume of water-saturated dichloromethane to extract once, combine the dichloromethane, recover, concentrate, and dry to obtain the total alkaloid perchlorate 2 of Lianxin.
Embodiment 3
[0042]A method for preparing and purifying perchlorate of total alkaloids of lotus heart, which is characterized in that, taking 1 part of total alkaloids of lotus heart powder, adding an appropriate amount of commercially available perchloric acid to completely dissolve it, and then adding an appropriate amount of purified water to dilute to perchloric acid The mass concentration is 40%, adding 0.25 times the volume of water-saturated dichloromethane to extract three times, combining the dichloromethane, recovering, concentrating, and drying to obtain the total alkaloid perchlorate 3 of Lianxin.
