Embodiment 1

[0025] The ultra-high pressure extraction method of embodiment 1 Periplaneta americana of the present invention

[0026] Weigh 1000g of Periplaneta americana, crush it, add 6 times the amount (v / w) of 60% ethanol, pack it into a flexible container and seal it. Put it in an ultra-high pressure extractor, increase the pressure to 300MPa, pressurize 5 times, each time for 5min, the temperature is 40°C, release the pressure, open the cover to take a sample, and filter. The filtrate was concentrated under reduced pressure at 60°C until there was no ethanol smell, and the relative density was 1.05 (measured at 50°C). The concentrated solution was refrigerated at 0°C for 24 hours, and the upper layer of oil was absorbed with filter paper, and the lower layer was centrifuged in a high-speed refrigerated centrifuge. The temperature is 5°C, and the rotation speed is 10000r / min. After centrifugation, the supernatant was concentrated under reduced pressure at 60° C., dried, and pulverize...

Embodiment 2

[0027] The ultra-high pressure extraction method of embodiment 2 Periplaneta americana of the present invention

[0028] Weigh 1000g of Periplaneta americana, crush it, add 7 times the amount (v / w) of 75% ethanol, pack it into a flexible container and seal it. Put it in an ultra-high pressure extractor, increase the pressure to 400MPa, pressurize 3 times, each time for 10min, the temperature is 50°C, release the pressure, open the cover to take a sample, and filter. The filtrate was concentrated under reduced pressure at 70°C until there was no ethanol smell, and the relative density was 1.08 (measured at 50°C). The concentrated solution was refrigerated at 5°C for 36 hours, and the upper layer of oil was absorbed with filter paper, and the lower layer was centrifuged in a high-speed refrigerated centrifuge. The temperature is 10°C, and the rotation speed is 10000r / min. After centrifugation, the supernatant was concentrated under reduced pressure at 70° C., dried, and pulveri...

Embodiment 3

[0029] The ultra-high pressure extraction method of embodiment 3 Periplaneta americana of the present invention

[0030] Weigh 1000g of Periplaneta americana, crush it, add 8 times the amount (v / w) of 70% ethanol, pack it into a flexible container and seal it. Put it in an ultra-high pressure extractor, increase the pressure to 400MPa, pressurize 3 times, each time for 15min, the temperature is 60°C, release the pressure, open the cover to take a sample, and filter. The filtrate was concentrated under reduced pressure at 75°C until there was no ethanol smell, and the relative density was 1.10 (measured at 50°C). The concentrated solution was refrigerated at 10°C for 48 hours, and the upper layer of oil was absorbed with filter paper, and the lower layer was centrifuged in a high-speed refrigerated centrifuge. The temperature is 15°C, and the rotation speed is 10000r / min. After centrifugation, the supernatant was concentrated under reduced pressure at 75° C., dried, and pulver...

Abstract

The invention discloses an ultrahigh-pressure extraction method for american cockroach. The ultrahigh-pressure extraction method for american cockroach comprises the following steps: (1) taking american cockroach powder, adding water or ethanol solution with a concentration of 50-90%, and extracting for 1-5 times and for 5-20 minutes every time under an ultrahigh pressure to obtain an extract, wherein the pressure for the ultrahigh-pressure extraction is 100-800MPa, and the temperature is 20-80 DEG C; (2) filtering the extract in the step (1) to obtain a supernatant, and concentrating the supernatant to obtain a concentrate; (3) refrigerating the concentrate in the step (2) for 24-48h, removing upper-layer oil, centrifuging to obtain a supernatant, concentrating, drying and crushing. The ultrahigh-pressure extraction method disclosed by the invention is capable of effectively extracting the effective ingredients of american cockroach, high in yield, simple and convenient to operate, and good in application prospect.

Description

technical field [0001] The invention relates to an ultra-high pressure extraction method of Periplaneta americana. Background technique [0002] Periplaneta americana (Periplaneta americana) is an insect belonging to the genus Periplaneta in the subclass Insecta Pterosae, Blatella order, Blattedae, commonly known as "cockroach". Taste: salty, cold; Cure: blood stasis syndrome with hard cold and heat, broken accumulation, closed throat, internal cold without seeds". In recent years, as our country attaches great importance to the research and development of traditional Chinese medicine resources, some scholars have made further research and made gratifying achievements. Good results have been achieved in the treatment of traumatic wounds. [0003] The active ingredients of Periplaneta americana include amino acids, peptides, ketones and trace elements. At present, the extraction of Periplaneta americana usually adopts conventional methods such as extraction, reflux extract...
