Embodiment 1
[0026] Take the dried black wolfberry, pulverize it into a coarse powder, and pass it through a 60-mesh stainless steel screen. Accurately weigh 100g of black wolfberry powder, add 3% sucrose by mass, wrap it with filter paper and put it into a Soxhlet extractor, add 500mL of 90% ethanol, heat at 80°C, and heat to reflux for 2h. Filtrate to obtain the primary extract, put the filter residue into a beaker, add 5 times the mass of 60% ethanol solution, perform ultrasonic extraction at an ultrasonic frequency of 50kHz-60kHz, the ultrasonic temperature is 60°C, and the ultrasonic time is 50min, and filter to obtain a secondary For the extract, combine the two extracts, and carry out vacuum distillation in a rotary evaporator until no ethanol flows out to obtain black wolfberry extract. Accurately weigh 10g of black wolfberry extract and place it in a 1000mL beaker, add 500mL of 20% ethanol to dissolve (H1). After the dissolution is complete, use a 50nm ceramic microfiltration mem...
Embodiment 2
[0028] Take the dried black wolfberry, pulverize it into a coarse powder, and pass it through a 60-mesh stainless steel screen. Accurately weigh 50g of black wolfberry powder, add 3% sucrose by mass, wrap it with filter paper and put it into a Soxhlet extractor, add 500mL of 50% ethanol, heat at 50°C, and heat to reflux for 2.5h. Filter to obtain the primary extract, put the filter residue into a beaker, add 6 times the mass of 55% ethanol solution, and perform ultrasonic extraction at an ultrasonic frequency of 50kHz-60kHz, the ultrasonic temperature is 65°C, and the ultrasonic time is 50min. For the extract, combine the two extracts, and carry out vacuum distillation in a rotary evaporator until no ethanol flows out to obtain black wolfberry extract. Accurately weigh 10g of black wolfberry extract and place it in a 1000mL beaker, add 500mL of 20% ethanol to dissolve (H1). After the dissolution is complete, use a 200nm ceramic microfiltration membrane to filter, and the cut-...
Embodiment 3
[0030] Take the dried black wolfberry, pulverize it into a coarse powder, and pass it through a 60-mesh stainless steel screen. Accurately weigh 150g of black wolfberry powder, add 3% sucrose by mass, wrap it with filter paper and put it into a Soxhlet extractor, add 450mL of 100% ethanol (absolute ethanol), heat at 90°C, and heat to reflux for 1h. Filter to obtain the primary extract, put the filter residue into a beaker, add 7 times the mass of 70% ethanol solution, and perform ultrasonic extraction at an ultrasonic frequency of 50kHz-60kHz, the ultrasonic temperature is 70°C, and the ultrasonic time is 40min. For the extract, the two extracts were combined, subjected to vacuum distillation in a rotary evaporator, and the filtrate was distilled under reduced pressure until no ethanol flowed out to obtain black wolfberry extract. Accurately weigh 10g of black wolfberry extract and place it in a 1000mL beaker, add 500mL of 20% ethanol to dissolve (H1). After the dissolution i...
