Embodiment 1
[0020] A preparation method of Xuangui ointment, comprising the steps of:
[0021] (1) Weigh 40% Angelica sinensis, 40% Xuanhu, and 20% dried ginger by weight.
[0022] (2) Add 75% ethanol aqueous solution with a volume concentration equivalent to 5 times the mass of Angelica sinensis and dried ginger to the angelica and dried ginger, reflux for extraction for 2 hours, filter, recover ethanol from the filtrate and concentrate to a relative density at 80°C 1.20, let cool, extract with n-butanol, recover n-butanol from the extract and concentrate to obtain extract 1;
[0023] (3) Add the Herba Pediaceae to an aqueous ethanol solution with a volume concentration of 75% equivalent to 5 times the mass of Herba Pediaceae, reflux for extraction for 2 hours, filter, recover the ethanol from the filtrate and concentrate it to a concentrated solution with a relative density of 1.20 at 80°C , adjust the pH value to 7.5, extract with n-butanol, recover n-butanol from the extract and conc...
Embodiment 2
[0027] A preparation method of Xuangui ointment, comprising the steps of:
[0028] (1) Weigh 30% Angelica sinensis, 40% Xuanhu, and 30% dried ginger by weight.
[0029] (2) Add 99% ethanol aqueous solution with a volume concentration equivalent to twice the mass of angelica and dried ginger to the angelica and dried ginger, reflux for extraction for 1 hour, filter, recover ethanol from the filtrate and concentrate it to a relative density at 80°C 1.05, let it cool, extracted with ethyl acetate, recovered ethyl acetate from the extract and concentrated to obtain extract 1;
