Background technology
Herba Centipedae is the dry herb of feverfew Herba Centipedae.The property hot, warm, return lung meridian, have dispersing wind-cold, clearing the nasal passage, the effect of cough-relieving is used for headche due to wind-cold, cough with copious phlegm, it is obstructed to have a stuffy nose, the nasal sinusitis watery nasal discharge.Now extracted from centipeda volatile oil and isolated 84 chemical constituents, identified 55 chemical constituents, recall rate is 65.5%, and wherein the content with acetic acid chrysanthene ester is the highest, can reach more than 50%.At present, the research that centipeda volatile oil is used for the treatment of gynecological inflammation not yet has the research report, for this reason, is necessary that the effect that centipeda volatile oil is used for the treatment of gynecological inflammation further studies.
Gynecological inflammation is women's common disease, mainly refers to the inflammation of female sex organ, specifically comprises female vulva inflammation, vaginitis, cervicitis, pelvic inflammatory disease etc.The Main Pathogenic Bacteria kind is escherichia coli, staphylococcus aureus, bacillus pyocyaneus, streptococcus, Candida albicans, yeast etc.
Summary of the invention
The present invention at first provides the application of a kind of centipeda volatile oil in prevention or treatment gynecological inflammation.
The present invention also provides the application of a kind of centipeda volatile oil in preparation prevention or treatment gynecological inflammation medicine.
Wherein above-mentioned centipeda volatile oil prepares by the following method: adopt supercritical CO
2Fluid extraction method extraction Herba Centipedae, extracting pressure 20-30Mpa, extraction time 1-3h, extraction temperature 30-50 ℃.
Above-mentioned centipeda volatile oil can also prepare by the following method: Herba Centipedae is added 5-15 times of water soaking, then in volatile oil extractor, extract volatile oil 2-6 hour, collect oil water mixture, extracted with diethyl ether, reclaim ether, obtain centipeda volatile oil.
Above-mentioned centipeda volatile oil has stronger bacteriostatic activity to escherichia coli, streptococcus, yeast and Candida albicans, can be used as antibacterial; The Main Pathogenic Bacteria kind of gynecological inflammation is escherichia coli, staphylococcus aureus, bacillus pyocyaneus, streptococcus, Candida albicans, yeast etc., therefore, centipeda volatile oil can be used for prevention or treatment gynecological inflammation, such as vulvitis, vaginitis, cervicitis, pelvic inflammatory disease etc., also can be used for preparing the medicine of prevention or treatment gynecological inflammation.
When centipeda volatile oil is used for prevention or treatment gynecological inflammation, can use separately, also can cooperate other pharmaceutic adjuvants to be made into suppository, tablet etc., also can be with the use of other drug compatibility etc.The consumption of centipeda volatile oil when being used for prevention or treatment gynecological inflammation is 0.0001-1000mg/Kg, and preferred consumption is 0.001-100mg/Kg, and further preferred consumption is 0.01-10mg/Kg.

Embodiment 3
The preparation of centipeda volatile oil: take by weighing Herba Centipedae medical material 500g, adopt supercritical CO
2The fluid extraction instrument extracts volatile oil, extracting pressure 25Mpa, and extraction time 1.5h, 45 ℃ of extraction temperature obtain centipeda volatile oil 7.2ml.
The research of embodiment 4 centipeda volatile oil In Vitro Bacteriostatics
For trying strain:
Escherichia coli (ATCC8739), streptococcus (ATCC19615), yeast (ATCC10231), Candida albicans (ATCC90029), Institute of Microorganism, Academia Sinica.
Culture medium:
(1) beef-protein medium: Carnis Bovis seu Bubali cream 3g, peptone 10g, NaCl5g, agar 1.5%-2.0% (fluid medium does not contain agar), water 1000mL, pH7.0-7.2 (using the NaOH solution of 1.0mol/L to regulate pH).
(2) YPD culture medium: yeast soaks powder 10g, peptone 20g, glucose 20g, agar 1.5%-2.0% (fluid medium does not contain agar), water 1000mL, natural pH value.
The preparation of bacteria suspension:
Be inoculated in the corresponding fluid medium from the one ring thalline of picking on the thalline inclined-plane of overactivation, put into constant-temperature shaking incubator and be cultured to exponential phase.Draw respectively the confession examination bacterium liquid 0.5mL of above incubation time, add sterilized water doubling dilution to 10
5-10
6ML
-1, for subsequent use.
Supply the reagent thing:
Contrast medicine: kanamycin sulfate (mass concentration is 6g/L), methyl hydroxybenzoate (mass concentration is 40g/L).
The centipeda volatile oil of investigational agent: embodiment 1
The mensuration of bacteriostatic activity:
Adopt the filter paper method to measure bacteriostatic activity.Use card punch, qualitative filter paper is made the roundlet scraps of paper (D=6mm), for subsequent use behind the autoclaving.Under the aseptic condition, the culture medium 25.00mL of the corresponding strain of impouring in sterilized culture dish makes solid plate after the cooled and solidified.Draw the bacteria suspension 200 μ L that prepared and join in the corresponding solid plate culture medium, utilize spreading rod with the coating of bacterium liquid evenly.Getting filter paper is attached to and contains on the bacterium flat board, on every filter paper, drip respectively 10 μ L(centipeda volatile oil low dose group), dosage group in the 20 μ L(centipeda volatile oils), 30 μ L(centipeda volatile oil high dose group) centipeda volatile oil, kanamycin sulfate 15 μ L and methyl hydroxybenzoate 20 μ L, every ware pastes 3, notes during subsides will maintaining a certain distance between the filter paper.Place 37 ℃ of incubators to cultivate 24h escherichia coli, streptococcus, Candida albicans, yeast places 30 ℃ of incubators to cultivate 48h.Choose the obvious plane-table operation diameter of inhibition zone after cultivating end, the result gets the meansigma methods of repeated trials.
Result and conclusion:
The basic, normal, high dosage group of centipeda volatile oil, kanamycin sulfate group and methyl hydroxybenzoate group are as shown in table 1 for the Antibacterial Activity result of examination strain to 4 strains.
Table 1 trial drug is to the bacteriostatic activity for the examination strain
Annotate: with high dose group ratio, #P 0.05, with kanamycin sulfate group ratio, * P〉0.05, with methyl hydroxybenzoate group ratio, ▲ P<0.05
As shown in Table 1, the centipeda volatile oil of embodiment 1 all has stronger bacteriostatic activity to escherichia coli, streptococcus, Candida albicans and yeast, and the strongest to colibacillary bacteriostatic activity.Middle dosage group compares bacteriostatic activity and the high dose group of 4 strains for the examination strain, no difference of science of statistics (P〉0.05), middle dosage group compares bacteriostatic activity and the kanamycin sulfate group of 4 strains for the examination strain, no difference of science of statistics (P〉0.05), middle dosage group compares bacteriostatic activity and the methyl hydroxybenzoate group of 4 strains for the examination strain, variant (P<0.05) is better than methyl hydroxybenzoate to 4 strains for the bacteriostatic activity that tries strain.
