Embodiment 1

[0024] In the embodiment of the present invention, a kind of efficient and gentle method for preparing muscone comprises the following steps:

[0025] 1) Crush musk, pass through a 60-mesh sieve, soak in 75v% ethanol at 40°C for 3 hours, then reflux with 8 times the weight of 75v% ethanol for 3 times, reflux for 3 hours each time, filter, and take the filter residue and filtrate for later use.

[0026] 2) Reflux the filter residue with 8 times the weight of water and extract twice for 3 hours each time, filter, collect the filter residue, and combine the filtrate with the filtrate in step 1) for later use.

[0027] 3) Soak the filter residue in step 2) with hot water at 50°C for 4 hours, and then use 6 times the mass of water for injection for hot-press distillation extraction for 4 hours. Hot-press extraction needs to control the pressure of the container at 0.3MPa and the temperature at 90°C. Prepare hot-pressed extract.

[0028] 4) Combine the hot-pressed extract with the ...

Embodiment 2

[0034] In the embodiment of the present invention, a kind of efficient and gentle method for preparing muscone comprises the following steps:

[0035] 1) Crush musk, pass through a 100-mesh sieve, soak in 95v% ethanol at 50°C for 5 hours, then reflux extract with 15 times the weight of 95v% ethanol for 4 times, reflux for 4 hours each time, filter, and take the filter residue and filtrate for later use.

[0036] 2) Reflux the filter residue with 15 times the weight of water to extract 3 times, extract for 4 hours each time, filter, collect the filter residue, and combine the filtrate with the filtrate in step 1) for later use.

[0037] 3) Soak the filter residue in step 2) with hot water at 55°C for 8 hours, and then use 9 times the mass of water for injection for hot-press distillation extraction for 6 hours. Hot-press extraction needs to control the pressure of the container at 0.5MPa and the temperature at 125°C. Prepare hot-pressed extract.

[0038] 4) Combine the hot-pre...

Embodiment 3

[0044] In the embodiment of the present invention, a kind of efficient and mild method for preparing muscone comprises the following steps:

[0045] 1) Crush the musk, pass through a 80-mesh sieve, soak in 95v% ethanol at 45°C for 4 hours, then reflux with 12 times the weight of 95v% ethanol for 3 times, reflux for 3.5 hours each time, filter, and take the filter residue and filtrate for later use.

[0046] 2) Reflux the filter residue with 12 times the weight of water and extract twice for 3.5 hours each time, filter, collect the filter residue, and combine the filtrate with the filtrate in step 1) for later use.

[0047] 3) Soak the filter residue in step 2) in hot water at 52°C for 6 hours, and then use 7.5 times the mass of water for injection to extract by hot-press distillation for 5 hours. Hot-press extraction needs to control the pressure of the container at 0.4MPa and the temperature at 110°C. Prepare hot-pressed extract.

Abstract

The invention discloses a method for preparing musk ketone efficiently and mildly. The method comprises the following steps: crushing musk, sieving musk, soaking musk by using ethanol, performing reflux extraction by using ethanol, and performing reflux extraction by using water to obtain a filtrate; soaking a filter residue by using hot water, and performing hot-pressing distillation extraction to obtain a hot-pressed extract; concentrating the hot-pressed extract and the filtrate, centrifuging, washing, and dissolving in distilled water to obtain a dissolved solution; adjusting the pH of the dissolved solution, filtering by using a ceramic membrane, circularly washing, adding pure water for dissolving, decolorizing, filtering, and performing spray drying to obtain the musk ketone. By the method, the purity of the musk ketone can be increased, and reaches above 99%; the preparation process is simple, and easy to operate; a treatment condition is mild, so that the musk ketone is not affected; the extracting effect is good, more than 99% of the musk ketone in the musk can be extracted; the method has the advantages of high efficiency, rapidness, achievement of high purity, and the like.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a method for preparing muskone efficiently and mildly. Background technique [0002] Musk is made from the dried secretion of the male gland sac of deer musk deer. It is a high-grade spice. If you put a little in the room, it will fill the room with a delicate fragrance and a very different smell. Musk is not only fragrant and pleasant, but also has a long-lasting fragrance. Musk has been used in China for a long time. Du Fu, a poet of the Tang Dynasty, met in the poem "Lilac": "Falling into the orchid musk at night". Musk is an important raw material for the preparation of high-end essence. Ancient literati, poets, and painters all added a little musk to the finest musk material to make "musk ink" for writing and painting, which is fragrant and quiet. Musk is warm in nature, non-toxic, bitter in the mouth. Go into the heart, spleen, liver meridian, have one's ideas straigh...
