Embodiment 1

[0044] Preparation of active ingredient monomer neohecoside (extraction and separation process):

[0045] The whole herb of C.tuberosum was provided by Abdulai Jawo Bah, an African student at the International College of Tianjin University of Traditional Chinese Medicine. It was brought back from Africa, about 1.5kg, and extracted 3 times with 8 times the amount of 50% ethanol, 2 hours each time, and combined with 50% ethanol Extraction solution, recover ethanol under reduced pressure until there is no alcohol smell. Add distilled water to dilute to 4L, filter and perform macroporous resin column chromatography, water-ethanol gradient elution (water-95% ethanol, v / v), and recover the solvent by distillation under reduced pressure to obtain the following five components: 30% ethanol Eluate 60g, 50% ethanol eluate 20g, 70% ethanol eluate 2.7g, 95% ethanol eluate 1.4g.

[0046] The 70% ethanol eluate was subjected to ODS column chromatography (water-100% acetonitrile gradient elut...

Embodiment 2

[0063] Effects of the new jellyfish saponin compound and C.tuberosum extract of the present invention on platelet aggregation

[0064] The in vitro platelet aggregation activity test system was used to test the effects of components and some compounds obtained from C.tuberosum 50% ethanol extract separated by macroporous resin column on platelet aggregation. The results showed that 70% ethanol eluate had the activity of inducing platelet aggregation. The 95% ethanol eluate has inhibitory activity on ADP-induced platelet aggregation.

Abstract

The invention relates to a novel hecogenin compound with a structural formula (I): (novel hecogenin,3-O-beta-D-glucose-(1-2)-[beta-D-glucose-(1-3)]-beta-D-glucose-(1-4)-beta-D-galactoside); after the reflowing extraction of C.tuberosum harb ethanol, obtained crude extract is implemented with column chromatography by macroporous resin, and is gradually eluted by water and ethanol; the obtained 70% ethanol eluate is implemented with ODS column chromatography, and is eluted by water and 100% acetonitrile; the 70% ethanol eluate has the purpose of inducing platelet aggregation activity aspect.

Description

technical field [0001] The invention relates to a plant extract of the genus Chlorophytum of Liliaceae and its preparation method and application, especially the saponin compound and extract of the genus Chlorophytum and its preparation method and application. Background technique [0002] Platelet aggregation and thrombosis are important causes of ischemic cardio-cerebral injury, and anti-platelet aggregation therapy can help reduce the occurrence of cardiovascular and cerebrovascular adverse events. The anti-platelet aggregation effect of steroidal saponins is one of its mechanisms of action as a drug for treating cardiovascular and cerebrovascular diseases, atherosclerosis, myocardial infarction and other diseases. [0003] Steroidal saponins are an important class of active ingredients in plants. They are widely used clinically as drugs for the treatment of cardiovascular and cerebrovascular diseases. Their indications include coronary heart disease, myocardial ischemia,...
