Embodiment example 1

[0035] The first step is to grind Pulsatilla pulsatillae into coarse powder, soak in water for 0.5-2h, heat and reflux extract 6-12 times the amount for 2-3 times, each time for 1-3h, filter, and combine the filtrates. The above-mentioned filtrate was concentrated under reduced pressure at 50-70°C to 0.5-1.0g raw medicinal materials / mL, refrigerated overnight at 0-4°C, separated from the gel, and filtered to obtain Pulsatilla pulsatilla extract.

[0036] In the second step, add sodium hydroxide solution to the aqueous solution of Pulsatillae extract to adjust the pH to 10-13, heat and boil for 4-10 hours, measure the pH every 30-60 minutes, keep it at pH 10-13, let it cool, add hydrochloric acid solution, and adjust the pH 3-7, centrifuge, remove the precipitate, and obtain the hydrolyzate of Pulsatilla radix extract

[0037] In the third step, the hydrolyzate of Pulsatillae extract is adsorbed by D101 or AB-8 or ADS-17 macroporous resin, eluted with water, 30-40% ethanol, 50-...

Embodiment example 2

[0046] The first step is to grind Pulsatilla pulsatillae into coarse powder, soak in 10-45% ethanol for 0.5-2h, heat and reflux extract 6-12 times the amount for 2-3 times, each time for 1-3h, filter, and combine the filtrates. The above-mentioned filtrate was concentrated under reduced pressure at 50-70°C to 0.5-1.0g raw medicinal materials / mL, without alcohol smell, refrigerated overnight at 0-4°C, gel separated, filtered, and Pulsatilla pulsatilla extract was obtained.

[0047] In the second step, add sodium hydroxide solution to the aqueous solution of Pulsatillae extract to adjust the pH to 10-13, heat and boil for 4-10 hours, measure the pH every 30-60 minutes, keep it at pH 10-13, let it cool, add hydrochloric acid solution, and adjust the pH 3-7, centrifuge, remove the precipitate, and obtain the hydrolyzate of Pulsatilla radix extract

[0048] In the third step, the hydrolyzate of Pulsatillae extract is adsorbed by D101 or AB-8 or ADS-17 macroporous resin, eluted with...

Embodiment example 3

[0057] The first step is to grind Pulsatilla pulsatillae into coarse powder, soak in 45-95% ethanol for 0.5-2h, heat reflux to extract 6-12 times the amount for 2-3 times, each time for 1-3h, filter, and combine the filtrates. The above-mentioned filtrate was concentrated under reduced pressure at 50-70°C to 0.5-1.0g raw medicinal materials / mL, without alcohol smell, refrigerated overnight at 0-4°C, gel separated, filtered, and Pulsatilla pulsatilla extract was obtained.

[0058] In the second step, add sodium hydroxide solution to the aqueous solution of Pulsatillae extract to adjust the pH to 10-13, heat and boil for 4-10 hours, measure the pH every 30-60 minutes, keep it at pH 10-13, let it cool, add hydrochloric acid solution, and adjust the pH 3-7, centrifuge, remove the precipitate, and obtain the hydrolyzate of Pulsatilla radix extract

[0059] In the third step, the hydrolyzate of Pulsatillae extract is adsorbed by D101 or AB-8 or ADS-17 macroporous resin, eluted with ...

Abstract

This invention relates to a preparation method of an ivy saponins ingredient 3-O-Alpha-L-rhamnopyranosyl-(1-2) (Beta-D-glucopyranosyl-(1-4))-Alpha-L-pyridine Nan ivy saponins arabinose and application of the ingredient to resisting tumors. The invention also relates to application of an extract, which is derived from Pulsatillachinensis (Bunge) Regel rhizome and contains the compound, to resisting the tumors above. The tumors include liver cancer, stomach cancer, glioma, breast cancer, cervical cancer, leukemia, colon cancer, lymphoma and the like.

Description

technical field [0001] The invention belongs to the technical field of medicine and veterinary medicine, and relates to a hedera saponin component 3-O-α-L-rhamnopyranose-(1→2)[β-D-glucopyranose-(1→4) ]-α-L-Arabinopyranosyl hedera saponin preparation method and its anti-tumor application, such as liver cancer, gastric cancer, glioma, breast cancer, cervical cancer, leukemia, colon cancer, lymphoma, etc. . [0002] The present invention also relates to the use of an extract containing the compound from the rhizome of Pulsatilla chinensis (Bunge) Regel as an anti-tumor agent as described above. Background technique [0003] The medicinal material of Pulsatilla is taken from the dried root of Pulsatilla genus Pulsatilla, which is bitter in taste and cold in nature. Return stomach, large intestine meridian, tool heat-clearing and toxic substances removing, the merit of cooling blood and stopping dysentery. For pyretotoxic blood dysentery, pruritus vulvae leukorrhagia, amoebic ...
