This invention belongs to the field of natural product chemistry technology, and relates to the extraction of natural products from the Saxifragaceae family (…). Saxifragaceae Juss.) *Changshan* ( Dichroa Lour.) Plant of the Chinese tallow tree ( Dichroa febrifuga Nine terpenoid compounds were isolated from *Dichroa febrifuga* extract. These compounds were obtained by sequentially separating the crude extract using D101 macroporous resin, silica gel column chromatography, HP20 column chromatography, ODS column chromatography, and HPLC. This invention also relates to investigating the bioactivity of these terpenoid compounds. The preparation method of this invention is simple, reproducible, and yields compounds with high purity, exhibiting good anti-inflammatory activity.

The invention provides a Chinese herbal medicine composition for preventing and treating coccidiosis of northern Shaanxi white cashmere goats and a preparation method and application thereof, and belongs to the technical field of Chinese herbal medicines. The Chinese herbal medicine composition comprises the following components in parts by weight: 10-20 parts of sweet wormwood, 8-16 parts of cape jasmine, 4-8 parts of rheum officinale, 8-16 parts of rhizoma atractylodis, 6-12 parts of radix bupleuri, 10-20 parts of oriental wormwood, 4-8 parts of astragalus membranaceus, 4-8 parts of liquorice, 5-12 parts of sophora alopecuroide and 4-9 parts of antifebrile dichroa. Natural Chinese herbal medicines such as artemisia apiacea and astragalus membranaceus produced in the northern Shaanxi region are developed and utilized, so that the problem of high incidence rate of coccidiosis of the northern Shaanxi white cashmere goats is solved, and the characteristics of medicinal value and no medicine residue of the artemisia apiacea and the astragalus membranaceus are utilized; when the feed additive is used for feeding the Shaanbei white cashmere goats, the problem of chemical medicine residues in animal products can be solved, the immunity of the goats is improved, and the coccidiosis morbidity of the goats is reduced.

The invention discloses yohimbine alkaloids as well as a preparation method and application thereof. The yohimbine alkaloid is at least one of a compound 1 to a compound 8. According to the application, novel yohimbine type alkaloid compounds, namely compounds 1 to 8, are found from neriaceae Abrus dichroa plant Codonopsis lanceolata, and research finds that the yohimbine type alkaloid compounds have a remarkable inhibitory effect on protein tyrosine phosphatase, and can be used for preparing a medicine for preventing and treating the diseases caused by the protein tyrosine phosphatase. The invention provides a novel scheme and product for preparing the protein tyrosine phosphatase inhibitor or a therapeutic drug based on the protein tyrosine phosphatase inhibitor.

The invention belongs to the technical field of biological medicine, and particularly relates to application of febrifugin dihydrochloride in preparation of a preparation for resisting porcine epidemic diarrhea virus infection. Specifically, the concentration of the febrifuginine dihydrochloride is 10 to 80 nmol / mL; the preparation for resisting porcine epidemic diarrhea virus infection comprises any one of a medicine, a disinfectant and a feed additive. The used dichroa B dihydrochloride belongs to a dihydrochloride form of traditional Chinese medicine extract dichroa B, and has the advantages of small toxic and side effects, high safety and better solubility. The antifebridin dihydrochloride can reduce cytopathy caused by the porcine epidemic diarrhea virus and inhibit the replication effect of the porcine epidemic diarrhea virus on cells, and provides a scientific and reliable theoretical basis for clinical treatment of the porcine epidemic diarrhea. The dichroa B dihydrochloride can also be used as a feed additive, can effectively prevent the epidemic of porcine epidemic diarrhea in pig farms, and reduces the economic loss of breeding diseases in animal husbandry.
