preparation example Construction

[0054] Preparation of the test solution: Accurately weigh 20.0 mg of Acacia saponin extract, dissolve it in methanol and transfer it to a 100 mL volumetric flask and set the volume to the mark as the test solution.

[0055] Preparation of the reference solution: Take 20.0 mg of each of Aegia saponins A, B, D, and H, weigh them accurately, add methanol to make a solution containing 200 μg per 1 ml, and obtain the solution.

[0056] Precisely draw 20 μL of the reference substance and the test solution, respectively, and inject them into the high-performance liquid chromatograph for determination.

Embodiment 1

[0058] Take 100kg of the medicinal material of Aegypti sinensis, crush and cut into coarse powder, put it into a heat reflux extraction tank, add 8 times the amount of 75% ethanol, heat and reflux for extraction 3 times, each time for 2 hours, release the extract, combine, filter, and concentrate the filtrate to 20L, add an equal volume of ethyl acetate to extract 3 times, combine the ethyl acetate solution, concentrate to a thick paste, then add 50L ethyl acetate to dissolve, filter, pass the filtrate through a neutral alumina column, and add 50L ethyl acetate Elution, TLC monitoring, collection of black bone saponin part, and concentrated to dryness, to obtain black bone saponin crude product (a) 3.2kg.

[0059] Take the crude product (a), add 100L of water, stir to dissolve, filter the plate and frame, pass the filtrate through a chromatographic column connected in series by polyamide (100-200 mesh, 20L)-macroporous resin (HPD-100, 100L), and wash thoroughly with water. Aft...

Embodiment 2

[0064] Take 100 kg of the medicinal material of Aegypti sinensis, crush and cut into coarse powder, put it into an extraction tank, add 10 times the amount of water, heat and reflux for extraction 3 times, each time for 2.5 hours, release the extract, combine, filter, and concentrate the filtrate to 50L, respectively Add an equal volume of ethyl acetate to extract 3 times, combine the ethyl acetate solution, concentrate to a thick paste, then add 50L ethyl acetate to heat to dissolve, filter, pass the filtrate through a neutral alumina column, and add 50L ethyl acetate to elute, TLC monitoring, collect the black bone saponin part, and concentrate to dryness to obtain 2.6kg of black bone saponin crude product (a).

[0065] Take the crude product (a), add 200L of water, stir to dissolve, filter the plate and frame, pass the filtrate through a chromatography column connected in series by polyamide (100-200 mesh, 40L)-macroporous resin (HPD-600, 150L), wash thoroughly with water A...

Abstract

The invention relates to an extract of a single traditional Chinese medicine, in particular, the invention relates to an extract of acacia saponin, a preparation method thereof, a pharmaceutical composition, an antitumor application and the like.

Description

technical field [0001] The invention relates to an extract of a single traditional Chinese medicine, in particular, the invention relates to an extract of acacia saponin, its preparation method, application, pharmaceutical composition and the like. Background technique [0002] Black bone vine, also known as Tongguangsan, Tongguang vine, is the cane of Marsdenia tenacissima (Roxb.) Wight et Arn., a plant of the genus Marsdenia R.Br. in the family Asclepiadaceae. Mainly produced in Yunnan, Guizhou and other places, it was first recorded in "Southern Yunnan Materia Medica". Black bone vine contains various chemical components such as steroidal ester glycosides, alkaloids, organic acids, polysaccharides, resins and pigments. It has a wide range of pharmacological activities, such as anti-tumor, immune regulation, liver protection and diuretic effects. [0003] At present, Xiaoaiping, which is made from a single traditional Chinese medicine of Wuguteng, has a variety of dosage...
