[0016] Preparation Example 1: Preparation of Dipsacus saponin X

[0017] Take 1 kg of Dipsacus chuanxiong medicinal material, crush it, pass through a 10-mesh sieve, add 10 times the amount (V / W) of 70% ethanol to soak overnight, reflux extraction twice, each time for 2 hours, filter the extract, and recover the ethanol until it is free. Add water to form a suspension, extract 3 times with n-butanol, combine the lower aqueous layer, apply the sample to the treated D101 macroporous resin (the weight ratio of resin to medicinal material is 1:1), wash 3 column volumes with water, discard Go, then elute 3 column volumes with 30% ethanol, discard, and finally wash 3 column volumes with 50% ethanol, collect the 50% ethanol eluate, concentrate, decolorize with activated carbon, and recrystallize to obtain a content of 98%. Dipsacus saponin X 6g.

Abstract

The present invention provides a new use of saponins X of dipsacus asperoides, more conctretely relates to the application of the saponins X of dipsacus asperoides in preparing a medicine for treatingor preventing cardiovascular and cerebrovascular diseases. Compared with the nifedipine, the saponins X of dipsacus asperoides described by the present invention can obviously decrease the rising oflimb-lead electrocardiogram J point and reduce the ischemic areas in treating rat myocardial ischemia; and compared with nimodipine, the saponins X of dipsacus asperoides described by the present invention can obviously improve rat behavior disorder and reduce the ischemic areas in treating local cerebral ischemic injury.

Description

technical field [0001] The invention relates to a new application of Dipsacus saponin X, in particular to an application of Dipsacus saponin X in the preparation of medicines for treating or preventing cardiovascular and cerebrovascular diseases. Background technique [0002] The traditional Chinese medicine Dipsacus has the functions of invigorating the liver and kidney, strengthening bones and muscles, continuing fractures, and stopping metrorrhagia. Jiuduan is mostly used for rheumatic arthralgia, injuries from falls, and salt Dipsacan is mostly used for soreness and weakness of the waist and knees. Dipsacus saponin X is extracted from Dipsacus and is the active ingredient of Dipsacus. The role of drugs containing Dipsacus saponin X in the prevention or treatment of cardiovascular and cerebrovascular diseases has not been reported. Through a large number of experimental studies, the inventors have discovered the medical use of a drug containing Dipsacus saponin X in the...
