Embodiment 1

[0037] Mix pinellia and ginger evenly at a weight ratio of 1:1, add 5 to 8 times the weight of water to extract for 3 to 5 hours, filter to obtain the extract, add 3 to 5 times the weight of water to the dregs, extract for 2 to 3 hours, and combine Two extracts; add ethanol to the extract until the alcohol mass content is 60-80%, let stand for 8-12 hours, centrifuge at 4500 rpm, take the supernatant, concentrate to 1-2g crude drug·mL -1 , the concentrated solution was extracted twice with diethyl ether (the amount of diethyl ether used each time was 0.8 to 1 times the volume of the concentrated solution), to obtain an ether layer and a water layer, and the water layer was adjusted to pH 7 with NaOH. After the solution was basically clarified, anion exchange Resin adsorption, and then washed with deionized water until colorless, with 0.5 ~ 1mol L -1 The resin was eluted with NaOH solution to obtain an eluent, which was adjusted to pH 3 with HCl, concentrated to dryness under re...

Abstract

The invention discloses an effective fraction of Xiao Ban Xia Tang. The effective fraction has physicochemical properties that: the effective fraction is a yellowish-brown extract, has certain moisture absorption and can be dissolved in hot water and ethanol; and the effective fraction mainly contains organic acid components, such as succinic acid, hydroxysuccinic acid, citric acid and linoleic acid. The invention also discloses a preparation method and application of the effective fraction of the Xiao Ban Xia Tang. An organic acid part extracted from the Xiao Ban Xia Tang has obvious pharmacological and pharmacodynamic effects. The effective fraction has an obvious effect of arresting vomiting; and through experimental models of pigeon emesis induced by both bluestone and cisplatin, results indicate that the organic acid part has obvious activity of arresting vomiting and can obviously reduce the vomiting frequency of pigeons; and the effective fraction has an effect of inhibiting gastric emptying of normal mice.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, and in particular relates to an effective part of Xiaobanxia decoction and its preparation method and application. Background technique [0002] Vomiting is a common clinical phenomenon, especially for cancer chemotherapy patients. Many patients often have to give up chemotherapy or radiotherapy due to fear of postoperative vomiting, thus delaying their illness. Although there are many drugs for treating vomiting at present, the effect is not ideal. Although drugs such as ondansetron and granisetron have certain effects on chemotherapy vomiting, these drugs are expensive and have certain side effects. It also limits their use to a certain extent. [0003] Vomiting belongs to the category of "qi inversion" in traditional Chinese medicine. It is believed that vomiting is caused by the loss of stomach harmony and the upward inversion of stomach qi. Traditional Chinese medicin...
