[0018] The invention provides a technical scheme: a process for preparing and extracting irone from the fresh root of Iris, comprising the following steps:
[0019] S1: Drying and crushing, wash the root of orris root, dry it, pass it through a 20-mesh sieve after crushing, and set it aside for later use. The drying method used is the hot air drying method, and the drying time is 15 minutes. The temperature is 120 degrees Celsius;
[0020] S2: Extraction, add 5 times the amount of ethanol to the spare raw material prepared in the previous step, extract under normal pressure for 4 hours under boiling point conditions, filter the extract, and recover the ethanol from the filtrate by distillation under reduced pressure to obtain the iris extract with a specific gravity of 1.10. Ointment, spare;
[0021] S3: Oxidation, under the environment of 40 degrees Celsius, dissolve the standby extract prepared in the previous step in a small amount of ethanol, and use 5-10% concentration o...

[0026] The invention provides a technical scheme: a process for preparing and extracting irone from the fresh root of Iris, comprising the following steps:
[0027] S1: Drying and crushing. Clean the root of orris root, dry it, pass it through a 30-mesh sieve after crushing, and set it aside for later use. The drying method used is microwave drying method, and the drying time is 4 minutes;
[0028] S2: Extraction, add 8 times the amount of ethanol to the spare raw materials prepared in the previous step, extract at normal pressure for 5 hours under boiling point conditions, filter the extract, and recover ethanol from the filtrate by distillation under reduced pressure to obtain iris extract with a specific gravity of 1.15. Ointment, spare;
[0029] S3: Oxidation, dissolve the spare extract prepared in the previous step in a small amount of ethanol at 50 degrees Celsius, and add an internal standard with 7% hydrogen peroxide solution according to the pH value of 9 and the liqu...

[0034] The invention provides a technical scheme: a process for preparing and extracting irone from the fresh root of Iris, comprising the following steps:
[0035] S1: Drying and crushing, wash the root of orris root, dry it, pass it through a 40-mesh sieve after crushing, and set it aside for later use. The drying method used is the hot air drying method, and the drying time is 20 minutes. The temperature is 150 degrees Celsius;
[0036] S2: Extraction, add 10 times the amount of ethanol to the spare raw material prepared in the previous step, extract under normal pressure for 6 hours under boiling point conditions, filter the extract, and recover the ethanol from the filtrate by distillation under reduced pressure to obtain iris extract with a specific gravity of 1.20. Ointment, spare;
[0037] S3: Oxidation, under the environment of 60 degrees Celsius, dissolve the spare extract prepared in the previous step in a small amount of ethanol, use 10% concentration of hydrogen ...
