Embodiment 1
[0020] Embodiment 1, the extraction of effective substance in Acer tartar, Acer Norway, Acer slender handle, Acer field, Eurasian maple leaf
[0021] Wash the leaves of Acer tartar, Acer Norway, Acer spp., Acer field, and Acer eurasia collected in October, and then crush them after natural drying or low-temperature drying (<50°C), and extract the effective substances by the following method :
[0022] Use ethanol-water mixed solvent (the percentage by volume of ethanol is 70%) with the above-mentioned pulverized Acer tartar, Acer Norway, Acer slender handle, Acer field respectively, and the dry leaves of Acer eutrophica in parts by weight ratio 20:1 Mix and extract by microwave for 16 seconds. The microwave frequency used is 2450MHz, the microwave output power is 700W, and the duty cycle is 4%. The obtained extract was filtered, and then extracted three times under the same conditions. After filtration, the three filtrates were combined, evaporated and concentrated at a low ...
Embodiment 2
[0023] Embodiment 2, the extraction of effective substance in Acer tartar, Acer Norway, Acer slender handle, Acer field, Eurasian maple leaf
[0024] Wash the leaves of Acer tartar, Acer Norway, Acer spp., Acer field, and Acer eurasia collected in October, and then crush them after natural drying or low-temperature drying (<50°C), and extract the effective substances by the following method :
[0025] Use acetone-water mixed solvent (the percentage by volume of acetone is 60%) to mix with the above-mentioned pulverized Acer tararum, Acer Norway, Acer slender handle, Acer pastoral, Acer eucalyptus dry leaves in parts by weight in a ratio of 25: 1. Combine, transfer to a glass container, and microwave for 12 seconds. The microwave output power is 800W, the microwave frequency is the same as above, and the duty cycle is 5%. Filter the treatment solution, add acetone-water mixed solvent under the same conditions to extract the residue again, repeat 3 times, after filtering, comb...
Embodiment 3
[0027] Embodiment 3, the extraction of effective substance in the Acer tartar, Acer Norway, Acer slender handle, Acer pastoral, Eurasian Acer
[0028] Wash the samaras of Acer tartar, Acer Norway, Acer slender handle, Acer field, and Acer samurai collected in October, dry them naturally or dry them at low temperature (<50°C), and then crush them, and use the following methods to extract effectively thing:
[0029] Use ethanol-water mixed solvent (volume and number ratio of ethanol and water is 60: 40) with above-mentioned pulverized Acer tartar, Norway maple, Acer spp. : 1 mixed, transferred to a glass container, microwaved for 20 seconds, with a microwave output power of 700W, a microwave frequency of 2500MHz, and a duty cycle of 3.6%. Filter the solution, and then extract 3 times under the same conditions. After filtering, combine the three filtrates, (reduced pressure) low-temperature evaporation and concentration, remove the organic solvent, and obtain an aqueous phase co...
