Embodiment 1

[0023] Embodiment 1: first the total flavonoids of sweet blue orchid is produced through the following process: the sweet green orchid is pulverized into coarse powder, crosses 0.8mm, adds 30 times of amount of 70% ethanol to extract and reflux 2 times, each time for 3 hours, use Filter through a 70 μm sieve, combine the two filtrates, recover ethanol, and concentrate to a concentrated solution with a dry matter of 0.1g / mL fennel; take the above concentrated solution, and use a macroporous resin of type HPD100 for purification. Add 20mL of ethanol concentrate to purify, let it stand for 4h to absorb, and use 40mL of water for each g of dry resin at 40mL·h -1 The flow rate is eluted, and the eluent is discarded; then use 125mL60% ethanol solution for each g of dry resin at 30mL·h -1 Flow rate elution, collect eluate, eluate is concentrated to dry matter ≥ 1g / mL, promptly obtains the total flavonoids of fennel of the present invention. Get again 30 parts of total flavonoids of ...

Embodiment 2

[0024] Embodiment 2: first the total flavonoids of sweet blue orchid are produced through the following process: first sweet green orchid is pulverized into a coarse powder, cross 1mm, add 40 times the amount of 80% ethanol to extract and reflux 3 times, each time for 4 hours, use Filter through an 80 μm sieve, combine the filtrates for 3 times, recover ethanol, and concentrate to a concentrated solution with a dry matter of 0.3g / mL fennel; take the above-mentioned concentrated solution and purify it with a macroporous resin of type HPD 400. Add 8mL of ethanol concentrate to the resin for purification, and after standing for 5h for adsorption, use 50mL of water per g of dry resin at 50mL·h -1 The flow rate is eluted, and the eluent is discarded; and then 100mL70% ethanol solution is used for each g of dry resin at 40mL·h -1 The flow rate is eluted, the eluate is collected, and the eluate is concentrated to a dry matter ≥ 1.15g / mL, to obtain the total flavonoids of the present ...

Embodiment 3

[0025] Embodiment 3: first the total flavonoids of sweet blue orchids are produced by the following process: first sweet green blue orchids are pulverized into coarse powder, pass 1.2mm, add 50 times the amount of 90% ethanol to extract and reflux 4 times, each time for 5 hours, Filter through a 90 μm sieve, combine the filtrates for 4 times, recover ethanol, and concentrate to a concentrated solution with a dry matter of 0.4g / mL fennel; take the above-mentioned concentrated solution and purify it with a macroporous resin of type HPD 600. The dry resin was purified by adding 6mL of ethanol concentrate, and after standing for 6h for adsorption, 60mL of water was used for each g of dry resin at a rate of 60mL·h -1 The flow rate is eluted, and the eluent is discarded; then use 110mL65% ethanol solution for each g of dry resin at 50mL·h -1 Flow rate elution, collect the eluate, concentrate the eluate to a dry matter ≥ 1.2g / mL, and then obtain the total flavonoids of fennel of the ...

Abstract

The invention discloses a dracocephalum moldavica general flavone orally disintegrating tablet and a preparation method thereof. The dracocephalum moldavica general flavone orally disintegrating tablet is prepared by dosing, pelletizing and tabletting 25 to 30 portions of dracocephalum moldavica general flavone, 9 to18 portions of disintegrating agents, 33 to 85 portions of filling agents, 1 to 5portions of binding agents, 0.5 to 1 portions of lubricant, and 1 to 3 portions of taste correcting agents. Compared with the prior art, the dracocephalum moldavica general flavone orally disintegrating tablet is a novel preparation with favorable taste and quick disintegration, has the characteristics of convenience in taking and quickness in taking effect, can solve the problem of the medicine taking of patients who swallow difficultly, can meet the requirement for the patients who take medicine without water, overcomes the problem of insufferable bitter taste of other tablets without tastecorrection, improves the conformance of patients, has the characteristic of quickness in disintegration, and can disintegrate within 15 to 60 seconds in the oral cavity once being contacted with saliva, thereby being an ideal pharmaceutical preparation for preventing arteriosclerosis, coronary heart disease and angina pectoris disease in a clinic.

Description

technical field [0001] The invention relates to an orally disintegrating tablet of total flavonoids of Xiangqinglan and a preparation method thereof. Background technique [0002] Dracocephalum Moldavica L. is an annual herb of Lamiaceae. It is a local Uighur medicine in Xinjiang and has rich medicinal resources. In Uighur medicine and folk, it is used to treat bronchitis, heart disease, high blood pressure and other diseases. The main components of Xiangqinglan are flavonoids and terpenes.
