Embodiment 1

[0031]Weigh 5kg of Tongkat Ali root, crush it to 10-30 mesh, put it into an ultrasonic extraction tank, add deionized water to the Tongkat Ali powder according to the ratio of 1g of Tongkat Ali powder to 6ml of deionized water, and extract by ultrasonic at 55°C 1 time, filter, then add deionized water to the filter residue according to the ratio of 1g filter residue to 6ml deionized water, and ultrasonically extract once at 55°C. And use a three-legged centrifugal bag 200 mesh centrifugal filter to take the filtrate; the filtrate is cooled to 12°C with chilled water and then centrifugally degreased with a tubular centrifugal device at 10000r / min; the degreasing liquid after centrifugal degreasing passes through a plate heat exchanger at a constant temperature Apply D101 macroporous adsorption resin at a flow rate of 0.5BV / hour at 15°C for resin chromatography, and wash with methanol with a volume concentration of 10% through a plate heat exchanger at a constant temperature of 3...

Embodiment 2

[0033] Weigh 5kg of Tongkat Ali root, crush it to 10-30 mesh, put it into an ultrasonic extraction tank, add deionized water to the Tongkat Ali powder according to the ratio of 1g of Tongkat Ali powder to 6ml of deionized water, and extract by ultrasonic at 55°C Once, filter, and then add deionized water to the filter residue according to the ratio of 1g filter residue to 6ml deionized water, and ultrasonically extract once at 55°C. The extraction time is 42min each time, and the ultrasonic frequency of extraction is 80KHZ. Centrifugal filtration with 200 mesh of three-legged centrifugal bag, take the filtrate; cool the filtrate to 15°C with chilled water, then use tubular centrifugal equipment to degrease at 30000r / min; degrease the degreasing liquid through a plate heat exchanger at a constant temperature of 15°C Apply D101 macroporous adsorption resin at a flow rate of 0.5BV / hour for resin chromatography. When eluting, use ethanol with a volume concentration of 10% to elute ...

Embodiment 3

[0035] Weigh 5kg of Tongkat Ali root, crush it to 10-30 mesh, put it into an ultrasonic extraction tank, add deionized water to the Tongkat Ali powder according to the ratio of 1g of Tongkat Ali powder to 6ml of deionized water, and extract by ultrasonic at 55°C Once, filter, and then add deionized water to the filter residue according to the ratio of 1g filter residue to 6ml deionized water, and ultrasonically extract once at 55°C. The extraction time is 42min each time, and the ultrasonic frequency of extraction is 80KHZ. Centrifugal filtration with 200 mesh of three-legged centrifugal bag, take the filtrate; cool the filtrate with chilled water to 14°C, and then use a tubular centrifugal device to degrease at 20,000r / min; the degreasing liquid passes through a plate heat exchanger at a constant temperature of 15°C Apply LX-T81 macroporous adsorption resin at a flow rate of 0.5BV / hour for resin chromatography. When eluting, first use pentanol with a volume concentration of 10...

Abstract

The invention provides a process for rapidly and efficiently extracting eurycomanone from eurycoma longifolia. The process includes the steps that the eurycoma longifolia is smashed and then ultrasonically extracted, an extracting solution is centrifugally filtered, and filtrate is taken; the filtrate is cooled and then centrifugally degreased; a degreasing solution is fed at constant temperature for resin chromatography, collected eluant is subjected to low-temperature evaporation and concentration through an MVR evaporator, obtained concentrated extract is diluted and then decolored, subjected to impurity removal and filtered, filtrate is subjected to low-temperature evaporation and concentration through the MVR evaporator again, absolute ethyl alcohol is added into obtained concentrated liquor, the materials are stirred to be uniform and then crystallized, and crystals are washed and subjected to vacuum drying. According to the process, ultrasonic extraction is adopted, the extraction time can be shortened, the extraction temperature can be reduced, and the extraction yield can be increased; a reagent is recycled through low-temperature evaporation and concentration of the MVR evaporator, and the overheating oxidation and evaporation cost of products can be reduced. The extraction rate of eurycomanone of the process reaches 90% or above, the product content and yield are relatively stable, and the process is suitable for industrial mass production.

Description

technical field [0001] The invention relates to a process for extracting ketone, in particular to a process for quickly and efficiently extracting ketone from Tongkat Ali. Background technique [0002] Eurycoma Longifolia (Eurycoma Longifolia) is known as Ali's crutch in Malay, also known as "Malaysian ginseng", "Malay ginseng" or "natural Viagra" known to the public. Called "Longjack". Tongkat Ali can help men regain health, strength and vitality and has great and amazing medicinal properties. According to the theoretical basis of traditional Chinese medicine, Yin Zhichao, director of the China Academy of Traditional Chinese Medicine, and members of his expert group believe that the effectiveness of Tongkat Ali, a natural plant, is closely related to its growth environment in the rainforest. Bitter, enters the spleen and kidney meridians, because of the bitter taste, it has a strong clearing and descending effect. Clearing away heat and detoxification, clearing will bene...
