Embodiment 1

[0101] Example 1: Rescue 2000g of Bing coarse powder, reflux extraction with 6 times 80% ethanol three times, extract for 2, 1, 1 hour respectively, filter, combine the filtrates, concentrate to extract, add 6000ml of water, heat in a water bath, stir , stand overnight, filter, the filtrate is concentrated to 1000ml, let cool to room temperature, filter, the precipitate is washed three times with an appropriate amount of water, dried, and crystallized with 10-50 times the amount of 50-95% ethanol to obtain crude glucoside Crystal, followed by repeated crystallization with 10-50 times the amount of 50-95% ethanol to obtain pure glucoside with a yield of 1.38%. According to the law, the content is 98.59%.

Embodiment 2

[0103] Take the pelicoside prepared by the method of Example 1, and adopt the well-known preparation method of the infusion solution in the technical field to prepare the pelicoside sodium chloride injection and the pelicoside glucose injection: the pelicoside 40 mg, Sodium Chloride 2.25g, made into Pelicoside Sodium Chloride Injection, its specification is 500ml, intravenous injection, 1 bottle each time, once a day; Glucoside injection, its specification is 500ml, intravenous injection, 1 bottle each time, once a day.

Embodiment 3

[0104] Example 3: Take 20 g of glucoside prepared by the method of Example 1, add an appropriate amount of water for injection, adjust the pH value to 7 with sodium carbonate, stir and dissolve, and then add an amount equivalent to 10-15% of glucoside Mannitol for injection is sterilized and filtered, its content is determined, and it is packaged in 1000 tubes, 20 mg per tube, sealed, and ready to be obtained. Intravenous injection, 40mg each time, once a day.

Abstract

The present invention relates to an ilex pedunculosa glycoside for curing cardio-cerebral vascular system diseases of coronary heart disease, angina pectoris, apoplexy and cerebral infarction, medicine composite containing ilex pedunculosa glycoside and its extraction separation method. Said extraction separation method includes the following steps: using ethyl alcohol to extract ilex pedunculosa to obtain extract, adding water into said extract, making centrifugal separation, concentrating supernatant fluid, making centrifugalization, washing precipitate by using proper quantity of water, drying and using ethyl alcohol to make crystallization so as to obtain the ilex pedunculosa glycoside pure product whose content can be up to above 98.0%.

Description

technical field [0001] The invention relates to a medicine for treating diseases of the cardiovascular and cerebrovascular systems, a health food and a preparation method thereof, in particular to the composition of the active ingredient of the traditional Chinese medicine, glucoside, the medicine containing glucoside, and the health food and their corresponding preparation methods. Background technique [0002] Jiubing is the bark of Ilex rotunda Thunb., a plant in the Ilex family Ilex family. It is mainly produced in Guangxi and Guangdong provinces. It has the effects of clearing away heat and detoxification, reducing swelling and relieving pain. For colds, tonsillitis, sore throat, acute gastroenteritis, rheumatic bone pain; external use for bruises, carbuncle furuncle sores, traumatic bleeding, burns and scalds. The chemical components mainly contain triterpenoid saponins, flavonoid glycosides, phenols, tannins, etc., and the content of saponins is relatively high, abou...
