Embodiment 1
[0028] The preparation of embodiment 1 gorgonian extract
[0029] 1) extract
[0030] (1) Crush and sieve the gorgonian raw material to obtain 60-mesh fine particles, extract with deionized water at a temperature controlled at 55°C; extract three times, the first time the ratio of solid to liquid is 1:6, and the second time is 1:4, 1:3 for the third time, 2 hours each time;
[0031] (2) After the extraction, the three filtrates are merged, and the MVR evaporator is used for low-temperature concentration, and the concentration to a specific gravity of 1.12 is to discharge the feed liquid for subsequent use;
[0032] 2) over resin
[0033] Purify the extracted and concentrated feed solution with a macroporous adsorption resin column HP20, the loading volume is 2 column volumes, first eluted with 20vol% low-concentration ethanol, the elution volume is 4 column volumes, and then 95vol% % high-concentration ethanol for elution, the elution volume is 2 column volumes, and the elu...
Embodiment 2
[0039] The preparation of embodiment 2 gorgonians extract
[0040] 1) extract
[0041] (1) Crush and sieve the gorgonian raw material to obtain 50-mesh fine particles, extract with deionized water at a temperature of 60°C; extract three times, the first time the ratio of solid to liquid is 1:6, and the second time is 1:4, 1:3 for the third time, 2 hours each time;
[0042] (2) After the extraction, the three filtrates are combined, and then concentrated at low temperature with an MVR evaporator, concentrated to a specific gravity of 1.11 to discharge the feed liquid, for subsequent use;
[0043] 2) over resin
[0044] Purify the extracted and concentrated feed solution with a macroporous adsorption resin column D101, the loading volume is 2 column volumes, first elute with 16vol% low-concentration ethanol, the elution volume is 3 column volumes, and then use 95vol% % high-concentration ethanol for elution, the elution volume is 2.5 column volumes, and the eluate is collecte...
Embodiment 3
[0049] The preparation of embodiment 3 gorgonians extract
[0050] 1) extract
[0051] (1) Crush and sieve the gorgonian coral raw material to obtain 70-mesh fine particles, extract with deionized water at a temperature controlled at 55°C; extract three times, the first time the ratio of solid to liquid is 1:6, and the second time is 1:4, 1:3 for the third time, 2 hours each time;
[0052] (2) After the extraction, the three filtrates are merged, and the MVR evaporator is used to carry out low-temperature concentration, and the concentration to a specific gravity of 1.13 is to discharge the feed liquid for subsequent use;
[0053] 2) over resin
[0054]Purify the extracted and concentrated material liquid with a macroporous adsorption resin column HPD300, the loading volume is 2 column volumes, first eluted with 20vol% low-concentration ethanol, the elution volume is 5 column volumes, and then 95vol% % high-concentration ethanol for elution, the elution volume is 2 column v...
