Embodiment 1
[0036] A process for extracting hematogenin from Huangteng fruit, comprising the following steps:
[0037] S1: Pulverizing the fruit of the yellow vine fruit and passing it through a 50-mesh sieve to obtain the fruit of the yellow vine fruit;
[0038] S2: Add 7 times of its weight 72% ethanol to the yellow vine fruit powder prepared in step S1, and extract twice under ultrasonic reflux under water bath conditions, the frequency of each ultrasonic wave is 620W, the temperature is 46°C, and the time is 14min. After the extraction is complete, combine the extracts, adjust the pH value of the extracts to 4.2, control the temperature at 46°C, decolorize and remove impurities by activated carbon for 1.2 hours, and obtain a decolorized solution after filtration;
[0039] S3: Concentrate and dry the primary decolorization solution obtained in step S2 to obtain an extract extract, which is dissolved in water at 52°C with 5.6 times the volume of the extract extract, and extracted twice ...
Embodiment 2
[0044] A process for extracting hematogenin from Huangteng fruit, comprising the following steps:
[0045] S1: Pulverizing the fruit of the yellow vine fruit and passing it through a 30-mesh sieve to obtain the fruit of the yellow vine fruit;
[0046] S2: Add 6 times the weight of 68% ethanol to the yellow vine fruit powder prepared in step S1, and extract twice by ultrasonic reflux under water bath conditions. The frequency of each ultrasonic wave is 560W, the temperature is 42°C, and the time is 15min. After the extraction is complete, combine the extracts, adjust the pH value of the extracts to 4, control the temperature at 42°C, decolorize and remove impurities by activated carbon for 1.4 hours, and obtain a decolorized solution after filtration;
[0047] S3: Concentrate and dry the primary decolorization solution obtained in step S2 to obtain an extract extract, which is dissolved in water at 50° C. with 5 times the volume of the extract extract, extracted twice with anhy...
Embodiment 3
[0052] A process for extracting hematogenin from Huangteng fruit, comprising the following steps:
[0053] S1: Pulverize the fruit of the yellow vine and pass it through a 60-mesh sieve to obtain the powder of the fruit of the yellow vine;
[0054] S2: Add 8 times its weight of 78% ethanol to the yellow vine fruit powder prepared in step S1, and extract it under ultrasonic reflux for 3 times under water bath conditions, the frequency of each ultrasonic wave is 720W, the temperature is 50°C, and the time is 12min. After the extraction is complete, combine the extracts, adjust the pH value of the extracts to 4.3, control the temperature at 50°C, decolorize and remove impurities by activated carbon for 0.8h, and obtain a decolorized solution after filtration;
[0055] S3: Concentrate and dry the primary decolorization solution obtained in step S2 to obtain an extract extract, which is dissolved in water at 55° C. with 6.2 times the volume of the extract extract, extracted 3 times...
