Embodiment 1

[0048] Example 1 Preparation of Cucurbitaceae plant Herpetospermum pedunculosum (Sex.) Baill.

[0049] Take 5 kg of the seeds of the medicinal material Boling melon seeds, crush them, soak them in 95% ethanol (5 times the amount), and extract the ethanol under reflux 3 times, each time for 1 hour, combine the extracts, concentrate until there is no alcohol smell, let stand to remove the oil layer, petroleum After removing residual oil with ether (one-time amount), ethyl acetate (one-time amount, one-time amount, one-time amount) extracted three times. Recover ethyl acetate to obtain dry powder. This part was subjected to repeated silica gel column chromatography, followed by dichloromethane: acetone 50:1, 30:1, 10:1, 5:1, 1:1 gradient elution, and collected 10:1, 5:1, 1:1 1 eluate, the crude product of wavelensin was obtained.

[0050] The crude boronsin was prepared by HPLC to obtain the boronsin (HPLC condition) with a purity of over 98%. The specific process is shown in ...

Abstract

The present invention discloses the extractive of Herpetospermum pedunculo-sum (Sex.) Baill as one cucurbitaceous plant and Herpetospermum pedunculo-sum (Sex.) Baill essence, their preparation process, derivative, medicinal composite and medicinal use, especially in preparing medicines for resisting virus, resisting liver damage and resisting tumor. Cell expermiment and animal experiment proves the high activity and less toxicity of Herpetospermum pedunculo-sum (Sex.) Baill essence.

Description

technical field [0001] The present invention relates to Herpetospermumpedunculosum (Sex.) Baill. extract of cucurbit plant Herpetospermumpedunculosum (Sex.) Baill., a preparation method of Herpetospermumpedunculosum and its derivatives, and a pharmaceutical composition of the extract and its derivatives , the use of the extract of poleng, poleng and its derivatives and pharmaceutical compositions thereof as medicines, especially the use in the preparation of antiviral, anti-liver damage and anti-tumor medicaments. It has been confirmed by cell experiments and animal experiments that bolensin has the advantages of high activity and low toxicity. Background technique [0002] Chronic viral hepatitis is a common infectious disease that seriously endangers people's health. According to statistics, hepatitis B patients alone account for 5% of the world's population. The incidence rate of viral hepatitis in my country ranks first in the world, that is, about 80% of hepatitis pat...
