Description
Technical field
The invention belongs to day biological technical field, more particularly to a kind of side that natural parahydroxyben-zaldehyde is prepared from bamboo shoots
Method.
Background technology
Bamboo shoots are the tender stems of grass family perennial plant bamboo, from ancient times referred to as " treasure in dish ", edible existing in China
The history of more than 2500 years.Bamboo shoots are fresh and tender, and meat is crisp, and delicious flavour is nutritious, are a kind of low sugar, low fat, the day of high protein
Right functional food.The main function of bamboo shoots at edible aspect, in addition, bamboo shoots also in the form of extract in food, drink, guarantor
It is strong(Function)It is used widely in the field such as food, natural drug and food additives and cosmetic additive agent.On bamboo shoots
Extraction separation, Structural Identification and the bioactivity research of chemical composition show that parahydroxyben-zaldehyde is the main component of bamboo shoots
One of, and show strong tyrosinase, it is rightγ- aminobutyric acid (GABA) transaminase and succinic semialdehyde dehydrogenase (
SSADH) inhibitory action.In addition, parahydroxyben-zaldehyde has good bacteriostasis, be usually used in food, cosmetics, medicine it is anti-
In terms of rotten, mould proof and sterilization.
Parahydroxyben-zaldehyde is the intermediate of a kind of important medicine, agricultural chemicals, dyestuff, spices and food feed additive,
With the fast development of China's medicine, agricultural chemicals and perfume industry, domestic, parahydroxyben-zaldehyde consumption figure rapid growth has much out
Hair prospect.Contain active aldehyde radical and phenolic hydroxyl group in its molecular structure, show special reactivity, synthesis can be extended many
Plant functional compounds.In terms of medicine, available for cardiovascular medicament esmolol, oral antibiotic oxyammonia benzylpenicillin
(Amoxicillin) and the synthesis of antibacterial trimethoprim (TMP) trimethoprim;In terms of agricultural chemicals, parahydroxyben-zaldehyde is main
Synthesis as herbicide Brominal and dichlobenil.In terms of spices, available for synthesis anisaldehyde, vanillic aldehyde, syringaldehyde, foreign jasmine
Many rare spices such as jasmine and raspberry ketone.Parahydroxyben-zaldehyde manufactures NAB National Association 0f Broadcasters as U.S.'s flavorant(FEMA)、(FAO/
WHO) the flavorant that the combination food additive Committee of Experts passes through, the addition scope in food is respectively 1~30 mg/
kg。
Antioxidant is an important component of food additives, can prevent food composition from causing change because of oxidation
Matter, in order to improve the oxidation resistance of food, often in food processing, storage, preservation process addition antioxidant, is used at present
More than comparing is artificial synthesized antioxidant, such as butylated hydroxy anisole synthetized oxidation preventive agent, such as butylated hydroxy anisole(BHA)
, dibutyl hydroxy toluene (BHT), propylgallate (PG) and tert-butylhydroquinone (TBHQ), but toxicity test shows,
Synthetized oxidation preventive agent has certain toxicity and carcinogenesis, and increasing country starts to limit or prohibits the use of some synthesis
Antioxidant.Therefore, the development trend that synthetized oxidation preventive agent is food industry from now on, exploitation safety are replaced with natural
Nontoxic, natural, efficient natural by be antioxidant research developing direction.
Research of the present invention to the chemical composition of bamboo shoots, extracts main component there is provided the preparation technology of parahydroxyben-zaldehyde,
The yield and purity for extracting parahydroxyben-zaldehyde are very high, and technique is simple and with low cost, and then enter industrialized production, satisfaction pair
The wilderness demand of hydroxy benzaldehyde commercially, is with a wide range of applications.
The content of the invention
It is an object of the invention to provide a kind of method that parahydroxyben-zaldehyde is extracted from bamboo shoots, applicant has to bamboo shoots
The research for imitating composition provides the technique for extracting parahydroxyben-zaldehyde, and operating procedure is few, and purity is high, is adapted to large-scale production.
Bamboo kind raw material available for the present invention is not particularly limited, and can be the bamboo not belonged to together, preferably Dendrocalamus
Bamboo shoots based on, such as imperial pearl, sinocalamus latiflorus, mangosteen.Bamboo shoots can be that bamboo shoots meat can also be bamboo shoots complete stool, can also be the useless of bamboo shoots
Gurry such as bamboo shoot head and bamboo shoot shell etc..
The method that the present invention prepares natural parahydroxyben-zaldehyde from bamboo shoots, comprises the following steps:
(1)Bamboo shoots are crushed, flowed back with the ethanol solution of 5~10 times of mass percent concentration 50~90% of bamboo shoots quality
Extract, flow back 2~3 hours every time, filtering, merging filtrate;
(2)By step(1)Filtrate is concentrated into after no ethanol, is separated precipitation, is obtained solution;
(3)By step(2)Solution is adsorbed with macroporous resin column, is eluted with the ethanol solution of mass percent concentration 40~90%,
The eluent containing target component is collected, no ethanol is concentrated into and obtains concentrate;Target product is determined using thin-layer chromatography;
(4)Concentrate carries out extraction 2~4 times using chloroform, ethyl acetate or n-butanol, and combining extraction liquid is concentrated to give leaching
Cream, admixes the silica gel of 1.5 times of medicinal extract quality, mixes sample silica gel and carries out conventional drying, is then loaded to silicagel column and is eluted;
(5)Eluted, collected as mobile phase using petroleum ether-acetone mixture or petroleum ether-ethyl acetate mixed liquor
After eluent containing target component, recycling design, parahydroxyben-zaldehyde crude product is obtained;
(6)By step(5)Parahydroxyben-zaldehyde crude product is recrystallized in organic solvent, and crystallographic is obtained after drying
Parahydroxyben-zaldehyde.
The step(2)Be separated into conventional centrifugation.
The step(3)It is to be completed on the conventional macroporous absorbent resin of prior art, macroporous absorbent resin is clear with ethanol
Also reusable after washing, macroporous absorbent resin is D-101, AB-8, HZ-816 or HP-20.
The step(4)In to mix sample and silica gel for chromatography be 100~300 mesh column layer chromatography silicone rubbers.
The step(5)Petrochina ether-acetone mixture be petroleum ether and acetone by volume the ︰ 1 of 8 ︰ 1~6 ratio mix
Close and be made;Petroleum ether-ethyl acetate mixed liquor is the ratio mixing system of petroleum ether and ethyl acetate by volume for the ︰ 1 of 6 ︰ 1~3
.
The step(6)Recrystallization solvent be petroleum ether and acetone by volume 1:The solution of 2 ratios mixing.
The present invention has following advantages and effect:Natural parahydroxyben-zaldehyde is prepared using such scheme, without using acid
Or the organic solvent such as alkali, preparation process is environmentally safe and with low cost, and product yield is high, is adapted to industrialization production.
