Embodiment 1

[0022]Example 1, the anti-vitiligo Ayurveda ethyl acetate extract is obtained according to the following preparation method: the first step, the Ayurveda seeds are crushed into Ayurveda powder and passed through a 10-mesh sieve to a 50-mesh sieve. Add 70% to 95% ethanol aqueous solution whose weight is 6 times to 20 times the weight of the Ayurveda seeds to the crushed Ayurveda seed, carry out ethanol extraction, soak to the heart, and heat and reflux at a temperature of 80°C to 90°C Extract 1 to 3 times, extract 0.5 hours to 2 hours each time, filter to obtain the first filtrate and filter residue, take out the filter residue and dry it to obtain a dry filter residue, add 6 to 20 times the weight of the dry filter residue to the dry filter residue 30% to 70% of the ethanol aqueous solution for ethanol extraction, heating and reflux extraction at a temperature of 80°C to 90°C for 1 to 3 times, each extraction for 0.5 hours to 2 hours, filtering to obtain the second filtrate, an...

Embodiment 2

[0026] Example 2, the anti-vitiligo Ayurveda ethyl acetate extract is obtained according to the following preparation method: the first step, the Ayurveda seed is crushed into Ayurveda powder and passed through a 10-mesh sieve or a 50-mesh sieve. Add 70% or 95% ethanol aqueous solution whose weight is 6 times or 20 times the weight of the Ayurveda seeds to the crushed Ayurveda seeds for ethanol extraction, soak until thoroughly, and heat and reflux at a temperature of 80°C or 90°C Extract 1 time or 3 times, extract 0.5 hours or 2 hours each time, filter to obtain the first filtrate and filter residue, take out the filter residue and dry it to obtain a dry filter residue, add 6 times or 20 times the weight of the dry filter residue to the dry filter residue The 30% or 70% ethanol aqueous solution of each part is subjected to ethanol extraction, and the temperature is 80°C or 90°C for heating and reflux extraction once or three times, each extraction is 0.5 hours or 2 hours, and ...

Embodiment 3

[0030] Embodiment 3, as the preference of the above-mentioned embodiment, in the first step, when adding 70% to 95% ethanol aqueous solution for ethanol extraction, the temperature is 86°C for heating and reflux extraction, after adding 30% to 70% ethanol aqueous solution When carrying out ethanol extraction, the heating and reflux extraction is carried out at a temperature of 86° C., and the heating methods of the heating and reflux extraction are all heating in a water bath.

Abstract

The invention discloses an ajowan-caraway seed ethyl acetate extract for resisting leucoderma and a preparation method thereof, and relates to the technical field of medicines. The ajowan-caraway seed ethyl acetate extract is prepared by a method comprising the following steps of: pulverizing ajowan-caraway seeds into 10-50 meshes of ajowan-caraway seed pulverized materials; adding 70-95 percent of ethanol water solution which is 6-20 times of weight parts of the ajowan-caraway seeds for performing ethanol extraction; soaking the seeds until the seeds are penetrated; and heating, back-flowing and extracting the seeds for 1-3 times at the temperature of 80-90 DEG C. The method is simple in process, and improves an utilization rate of the ajowan-caraway seed resources; the ajowan-caraway seed ethyl acetate extract has a high function of activating tyrosinase; the dosage of medicines for treating the leucoderma smaller than that of the medicines at present is used, so that the extract having the medicine efficiency as the same as that of a medicine for treating the leucoderma at present is achieved, and the ajowan-caraway seed resources are greatly saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medicines, and relates to an ayurvedic ethyl acetate extract for anti-vitiligo and a preparation method thereof. Background technique [0002] Ayur Weishi ( Trachyspermum ammi L. Sprague) is the ripe fruit of Ayurveria genus Ayurvedic, a traditional Uyghur medicinal material.
