Embodiment 1
[0024] A preparation method of May tea extract, which comprises the following steps:
[0025] 1) May tea leaf crushing: accurately weigh 1 kg of May tea leaf that was dried in a cool and ventilated condition, and crush to a particle size of about 200 μm to obtain May tea powder;
[0026] 2) Ultrasonic extraction: Use 95% ethanol to perform ultrasonic extraction on May tea powder, the mass ratio of solid to liquid is 1:10, the ultrasonic frequency is 24kHz, the ultrasonic extraction temperature is 25°C, and the ultrasonic extraction time is 25min. Filter through a mesh sieve to obtain filtrate I and slag I;
[0027] 3) Steam distillation extraction: use distilled water to reflux extract the filter residue I obtained in step 2), the mass ratio of solid to liquid is 1:6, reflux extraction twice, each time for 2 hours, filter while hot with a 180-mesh sieve, and combine the two The second extract was filtrate II;
[0028] 4) Concentration by vacuum distillation: combine the filt...
Embodiment 2
[0034] A preparation method of May tea extract, which comprises the following steps:
[0035] 1) Pulverization of May tea leaves: Accurately weigh 500g of May tea leaves dried in a cool and ventilated condition, and crush to a particle size of about 300 μm to obtain May tea powder;
[0036] 2) Ultrasonic extraction: use 90% ethanol to perform ultrasonic extraction on May tea powder, the mass ratio of solid to liquid is 1:15, the ultrasonic frequency is 40kHz, the ultrasonic extraction temperature is 30°C, the ultrasonic extraction time is 30min, and 120 mesh is used after extraction Filter through a mesh sieve to obtain filtrate I and slag I;
[0037] 3) Water steam distillation extraction: use distilled water to reflux extract the filter residue I obtained in step 2), the mass ratio of solid to liquid is 1:5, reflux extraction twice, each time for 1.5h, filter while hot with a 150-mesh sieve, and combine Two extractions were obtained to obtain filtrate II;
[0038] 4) Disti...
