Example Embodiment
[0021] The preparation method of the composition for reducing cholesterol of the present invention includes the steps of pretreatment, extraction, and post-treatment, and specifically includes:
[0022] A. Pre-treatment: Weigh separately according to the composition ratio of raw materials, crush and sieve separately for use;
[0023] B. Extraction: Mix the raw materials after pretreatment, add an ethanol solution with a solid-to-liquid volume ratio of 8-40 times and a mass percentage of 30-70%, and extract 2 to 4 times at 15 to 60°C. The extraction time is each time 12~48h, filter and concentrate at low temperature to obtain extract with relative density of 1.1~1.3 for later use;
[0024] C. Post-treatment: the extract is dried, crushed and sieved to obtain the target composition.
[0025] The crushing and sieving described in step A is 20-100 mesh sieve.
[0026] The ethanol solution described in step B has a mass percentage concentration of 40-60%.
[0027] The extraction time describ...
Example Embodiment
[0032] Example 1
[0033] Take 100 kg of Moringa leaves, 125 kg of hawthorn, and 175 kg of orange peel respectively, crush them through a 20-mesh sieve, mix them and put them into an extraction tank, add 3200 kg of 50% ethanol solution, heat to 45℃, extract at a constant temperature for 24 hours, and repeat the extraction three times. The obtained extracts are combined, and the extracts are concentrated under reduced pressure to 1 / 5 of the original volume (the relative density is 1.1 at 20°C) to obtain an extract. The extract is dried, crushed, and passed through a 40-mesh sieve to obtain the target composition.
Example Embodiment
[0034] Example 2
[0035] Take 300 kg of Moringa leaves, 100 kg of hawthorn, and 50 kg of orange peel, respectively, crush them through a 100-mesh sieve, mix them and put them into an extraction tank, add 4500 kg of 65% ethanol solution, heat up to 55°C, extract at constant temperature for 24 hours, and repeat extraction twice , The obtained extracts are combined; the extract is concentrated under reduced pressure to 1 / 3 of the original volume (the relative density is 1.3 at 20°C) to obtain the extract, which is dried, crushed, and passed through a 120 mesh sieve to obtain the target composition.
