Abstract
The present invention belongs to a method for extracting a bacteriostatic agent from a plant. In the method, phoenix tree bark is used as raw materials; after the raw materials are cleaned, dried, pulverized, extracted and concentrated, a product is obtained. The product contains anthraquinone compounds, flavonoid compounds, triterpene compounds, sterol compounds, etc. Because the compounds have certain bacteriostatic activity and high mildew resistance, the compounds are preferable natural bacteriostatic agents. The bacteriostatic agent is extracted with a reflux distillation method by using ethanol as solvent. The present invention has the advantages of safe and convenient production process and easy control, and is suitable for industrialized production.
Description
The invention belongs to a kind of method of from plant, extracting bacteriostatic agent and from this plant, extracting bacteriostatic agent.
Phoenix tree is outstanding tinkling of pieces of jade Ochnaceae (Platanaceae) plant, it comprises that London plane (Platanus ace-rifolia), oriental plane tree (Platanusorientalis), sycamore (Plata-nus occidentalis) are distributed in northern gentle subtropical zone, comprise some areas of China.The Chinese parasol tree bark comes off for several times every year, and output is considerable.The result sees by retrieval, up to the present, does not also find the bibliographical information that relevant Chinese parasol tree bark is utilized.
The object of the present invention is to provide a kind of good antimicrobial effect of utilizing the phoenix tree leather to make, harmless Chinese parasol tree bacteriostatic agent and the production method of this bacteriostatic agent.
The present invention is achieved in that it mainly is that bark with Chinese parasol tree is a raw material, and what make after cleaning, dry, pulverize, extract and concentrating is yellow fine particulate, and the article of fragranced are arranged, and promptly is this Chinese parasol tree bacteriostatic agent product.
The used Chinese parasol tree bark of the present invention is the bark that nature comes off.Because the bark of phoenix tree will come off for several times every year, the source of raw material is more extensive.Naturally after the Chinese parasol tree bark that comes off collected, when again this bark being cleaned, can wash removing more earlier with behind selection by winnowing or the screening dust out impurity; Also this bark directly can be put into water cleans.After being cleaned and finishing, this bark to dry processing, so that remove this bark surface and inner contained moisture.When bark was dried, its bake out temperature generally was controlled at 60～80 ℃ and gets final product.To pulverize after this bark oven dry, the granularity of its pulverizing can (diameter of sieve aperture be 355 ± 13u) by No. 3 sieves.After bark pulverized, the effective ingredient that its inside is contained is extracted, its extracting method be to be solvent with ethanol (95%), extracts with time heating up in a steamer extraction method.The number of times that extraction is heated up in a steamer in its time is preferably three times.The raw material of getting for the first time some is put into back and is heated up in a steamer in the extraction equipment, and then adds the ethanol of 4～7 times of material quantities, returns and heats up in a steamer extraction 2～4 hours, and soup is leached; For the second time, 4～6 times of ethanol that add the filter residue amount in filter residue again return and heat up in a steamer 1.5～3 hours, and soup is leached; For the third time, 3～4 times of ethanol that add the filter residue amount in filter residue again return and heat up in a steamer 1～2.5 hour, and soup is leached.In order to prevent that residual effective ingredient is arranged in the filter residue, in filter residue, add small amount of thermal ethanol and wash, at last soup is concentrated, be recovered as the ethanol of solvent first, the Chinese parasol tree bacteriostatic agent of extraction is separated out from soup.Soup is concentrated into not to be had alcohol, when anhydrous, can obtain being yellow fine grain Chinese parasol tree bacteriostatic agent.This Chinese parasol tree bacteriostatic agent that extracts has aromatic odor.Its rate of recovery is about 10% of a raw material weight.In the said extracted process, when leaching soup, preferably to take advantage of heat filtering at every turn, the composition of can remaining valid like this has bigger solvability in soup, so that obtain more extract.
With the Chinese parasol tree bacteriostatic agent that said method obtains, behind chemical analysis, learn: mainly contain the anthraquinone class in this Chinese parasol tree bacteriostatic agent.Flavonoids, triterpenes, sterols etc. play the compound of antibacterial and anti-inflammation functions.The content of anthraquinone class is 35～45% in the Chinese parasol tree bacteriostatic agent of its manufacturing; The content of flavonoids is 10～20%, and all the other are compounds such as triterpenes, sterols.Because compounds such as anthraquinone class, flavonoids have certain antibacterial activity, and stronger antifungi activity is arranged, so this bacteriostatic agent is a kind of desirable natural bacteriostatic agent.The test of this Chinese parasol tree bacteriostatic agent fungistatic effect sees Table one.
The minimum inhibitory concentration (mg/ml) of table one phoenix tree bark extract
Bacterium MIC mould MIC
Staphylococcus aureus 0.08 Penicillium citrinum 1
Sarcina lutea 0.4 bread mold 1
Bacillus pumilus 0.5 aspergillus flavus 0.5
Pseudomonas aeruginosa 0.8 trichophyton gypseum 0.25
Shigella dysenteriae 0.7
Salmonella 0.8 is annotated: MIC-bacterium system adopt broth bouillon put 37 ℃ cultivate observed result after 24 hours, all be the minimum inhibitory concentration of this extract with asepsis growth.
By table one as can be seen; This Chinese parasol tree bacteriostatic agent all has bacteriostasis significantly to pathogenic bacteria and mould, and suppresses the effect of the effect of bacterium greater than mould fungus inhibition.Suppress G
+The degree of bacterium is greater than G
-The degree of bacterium is particularly more obvious to the effect of staphylococcus aureus.(chief editor such as " practical antibiotic " Dai Ziying, the Shanghai People's Press publishes, and 1977; 19).
This Chinese parasol tree bacteriostatic agent is according to (hygiene teaching and research group of " sanitary toxicology experimental technique " Hunan medical college volume, 1979; 124～128) toxicology test that carries out proves: the Chinese parasol tree bacteriostatic agent is to skin, mucous membrane nonirritant.
According to (" Chinese pharmacopoeia pharmacopoeia commission compiles, and 1985; Appendix 86) the undue toxicity method of control result that the method described in is carried out proves: this Chinese parasol tree bacteriostatic agent is harmless.
Because the Chinese parasol tree bacteriostatic agent has the effect that suppresses bacterium, mould preferably.This Chinese parasol tree bacteriostatic agent experimental results show that as medicinal: wound, scald are had effects such as anti-inflammatory significantly, pain relieving, convergence.This Chinese parasol tree bacteriostatic agent also can play sterilization, anticorrosion as the preservative in the cosmetics.The effect of strong skin.As add the oral cavity that to keep healthy in the toothpaste; But add in the sock laying both deodorizations, can press down mould (being beneficial to the beriberi patient) again.The Chinese parasol tree bacteriostatic agent can also be as preservative in food, the beverage or natural colouring matter etc., and its nonhazardous, no stink etc. are a kind of desirable natural antiseptic agents.
Since this Chinese parasol tree bacteriostatic agent to produce raw material sources extensive, that effective ingredient is extracted is complete, safe, easy, be easy to control, is suitable for suitability for industrialized production.
