Example 5: Determination of Cytotoxicity of the Produced Extracts

(35) Cell Culture

(36) HaCaT-Cells (human in vitro spontaneous transformed keratinocytes from histologically normal skin) of DMSZ (German Collection of Microorganisms and Cell Cultures) were kept in Dulbecco's modified Eagle Medium (DMEM) with glutamax (Invitrogen/Gibco, Karlsruhe, Germany) with 10% fetal calf serum (Sigma Aldrich, Germany), 100 U/ml penicillin and 100 g/ml streptomycin and 1% NEAA.

(37) The cells were cultivated at 37 C., 5% CO.sub.2 and 95% humidity. The cells were subcultivated by removing the medium, adding 0.075% EDTA-solution in 1-fold PBS (phosphate-buffered salt solution) and subsequently incubated at 37 C. for 10 min. EDTA was removed und the HaCaT-cells were detached form the culture vessel by addition of 0.25% trypsin and 0.02% EDTA at 37 C. for 5 min. Afterwards, addition of fresh medium, centrifugation, exhausting of the medium and transferring in a new flask (ratio 1:5 or 1:10) was done. All experiments were performed using cells in the logarithmic growth phase.

(38) Sample preparation: Aqueous extracts were dissolved in water (100 mg/ml water) and ethanol extracts in dimethylsulfoxide, DMSO, (200 mg/ml DMSO).

(39) MTT-Assay According to Mosmann, 1983 (J. Of Immunological Methods 65, 55-63)

(40) In order to determine the concentration dependent cytotoxicity 210.sup.4 HaCaT-cells/sample well of a 96-well plate were transferred and incubated for 24 hours. Incubation of the HaCaT-cells was performed using 100 l of the medium containing various concentrations of the respective plant extract (see Table 2) or a 1.1 mixture of two plant extracts (see Table 3). Subsequently, 0.5 mg/ml MTT (3-(4,5-Dimethylthiazole-2-yl)-2,5-diphenyltetrazoliumbromide) were added and incubated for 4 hours. After dissolving the formazan crystals formed by the HaCaT-cells in 100 l DMSO (10 minutes shaking), absorption at 570 nm was measured (by means of Tecan Safire II Reader, Tecan Crailsheim, Germany). Doxorubicin was measured as reference. Cell vitality was determined according to the following formula:

(41) $\mathrm{Vitality}\left[\%\right]=\frac{\begin{array}{c}[\left(\mathrm{OD}\mathrm{sample}\mathrm{of}\mathrm{untreated}\mathrm{HaCaT}\text{-}\mathrm{cells}\right)-\\ \left(\mathrm{OD}\mathrm{sample}\mathrm{medium}\mathrm{control}\right)]*100\end{array}}{\left[\left(\mathrm{OD}\mathrm{untreated}\mathrm{HaCaT}\text{-}\mathrm{cells}\right)-\left(\mathrm{OD}\mathrm{medium}\mathrm{control}\right)\right]}$

(42) Statistical Analysis

(43) Three-fold determination (n=3) with three-fold replicate was performed and the results were stated as meansstandard deviation. IC.sub.50-values were calculated through the dose response curve which was created by use of a logistic regression curve with 4 parameters with the GraphPad Prism 5.01 Software or SigmaPlot 11.0. The individual curves are not shown herein. The determined IC.sub.50-values with standard deviations are summarized in Tables 2 and 3.

(44) Results

(45) None of the aqueous extracts Bid. alba (A-W), Sta. jamaicensis (B-W), Bur. simaruba (C-W), Stem. maritima and Aloe vera exhibits cytotoxicity compared to doxorubicin as cytotoxic reference compound (see Table 2).

(46) Ethanolic plant extracts of Bid. alba and Bur. simaruba exhibit no cytotoxicity compared to doxorubicin as cytotoxic reference compound. Ethanolic extracts of Sta. jamaicensis and Stem. maritima exhibit low cytotoxicity.

(47) Only the combinations with plant extracts of little higher IC.sub.50-values were analysed again to cytotoxicity (see Table 3).

Example 6: Determination of Anti-Inflammatory Activity

(48) Inhibition of 5-Lipoxygenase (5-LOX) through the individual extracts and their combinations (see Table 2 and 3) was spectroscopically determined (Baylac & Racine 2003). For this purpose 970 l of the phosphate buffer (21.2 g K3PO4 in 1 L H.sub.2O), pH 9.0 were mixed with 10 l of 1 mg/ml concentrated 5-LOX (lyophilized powder, Fluka) and 20 l various concentrations (0.48 g/ml to 250 g/ml) of the individual plant extracts and of the combinations (1:1 mixture). The mixture was incubated at room temperature for 10 minutes. Enzymatic reaction was initiated by adding of 20 l of 5 mM sodium linoleate (Sigma Aldrich). Reaction kinetic was determined at 234 nm every 5 seconds by means of a WPA Biowave II spectrophotometer. Nordihydroguaiaretic acid (NDGA) was used as positive control of a 5-LOX-selective inhibitor.

(49) Initial reaction speed was respectively determined from the slope of the linear part of the curve. Inhibition of the enzyme activity was calculated from three-fold experiments. Percentage of the initial activity was determined according to the following formula:
[%] of the initial activity=(IA.sub.controlIA.sub.sample)/IA.sub.control100

(50) wherein sample corresponds to an individual plant extract or a combination of at least two plant extracts and control equals to NDGA.

(51) Percentage [%] of the initial activity was (y-axis) graphically plotted as a function of the concentration of the respective plant extract or the combination (1:1 mixture), in order to determine the IC.sub.50-value as the concentration at which 50% of the enzyme activity is inhibited by the respective plant extract or the combination.

(52) Results

(53) Table 2 shows that ethanolic Bur. simaruba (C-E) extract exhibits significant inhibition of 5-Lipoxygenase. Consequently, an ethanol plant extract of Bur. simaruba (C-E withlCso=13213 g/ml) exhibits provably significant anti-inflammatory activity. The same applies for the respective ethanol individual extracts of Sta. jamaicensis (B-E with IC.sub.50=8410 g/ml) and Bid. alba (A-E with IC.sub.50=1397 g/ml).

(54) Table 3 shows that the combinations of the respective extracts exhibit an increased inhibition of 5-Lipoxygenase. These experiments respectively prove significant anti-inflammatory efficiency for Bid. alba, Sta. jamaicensis and Bur. simaruba as representatives for genus (a) Bidens, (b) Stachytarpheta and (c) Bursera. This efficiency may be attributed to the compounds, being contained in the species according to the invention and being extracted by means of the method according the invention, comprising verbascosides, flavonoids, iridoids, ipolamiides, fulvoipolamiides, sesquiterpene lactones and/or proazulenes.

Example 7: Determination of Antimicrobial Efficiency

(57) Antibacterial efficiency of the respective plant extract as individual extract and as combination of two extracts was analysed against the following test germs:

(58) Gram-Positive Bacteria Methicillin resistant Staphylococcus aureus MRSA NCTC 10442 (MRSA NCTC 10442) Staphylococcus aureus ATCC 25923 (S. aureus ATCC 25923) Staphylococcus epidermidis ATCC 14990 (S. epid. ATCC 14990)

(59) Gram-Negative Bacteria Pseudomonas aeruginosa ATCC 27853 (P. aerug. ATCC 27853) and Acinetobacter baumanii ATCC BAA747 (ATCC BAA747)

(60) Culture Preparation

(61) The bacteria were precultivated on Columbia medium with 5% sheep blood at 37 C. for 24 hours. On to two colonies were suspended in saline solution (0.9% NaCl) and adjusted to a turbidity of 0.5 McFarland standard which corresponds to 110.sup.8 colony forming units per milliliter (CFU/ml). Subsequently, the suspension was diluted to 110.sup.6 CFU/ml.

(62) Determination of the Minimal Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC)

(63) The MIC was determined by means of the microbouillon dilution process according to NCCLS (2006). For this purpose, the aqueous extracts were dissolved in water (w/v) and the ethanolic extracts in 5% DMSO (w/v) with 80 mg/ml each and Bur. simaruba as well as Aloe vera were suspended with 160 mg/ml. The extracts and the combinations (1:1 mixture) of two plant extracts were respectively transferred into a sample well of a 96-well plate. The individual extracts were respectively adjusted to a concentration of 4 mg/ml to 8 mg/ml and 0.03 mg/ml and the combinations to 2:2 mg/ml to 0.3:0.3 mg/ml. Subsequently, the bacteria suspensions with about 510.sup.5 CFU/ml in Mller Hinton medium (Fluka) were respectively added. The accordingly fitted 96-well plates were incubated at 37 C. for 24 hours.

(64) The MIC was determined at 600 nm on the basis of the turbidity. In order to determine the MBC, 3 l of the suspension of the respective sample well were spread on an full culture medium and incubated at 37 C. for 24 hours. The MBC was determined as lowest concentrations of the respective extract which totally kills the microorganisms.

(65) All experiments were performed as three-fold determination (Table 4 to 5). The antibiotics Vancomycin (briefly: Van) and Streptomycin (briefly: Strep) were used parallely to each experimental approach as positive control for antimicrobial efficiency (Table 5c). Respectively one of the mentioned test germs was carried along with the respectively solvent (water, DMSO) as negative control for an inhibiting effect by the used solvent. In comparison to the growth control without any addition, no negative influence on the growth was observed for all negative controls.

(66) A sterility control confirmed sterility of the used media (data not shown). The composition of the controls is summarized in Table 5b.

(67) Results

(68) Table 4a summarizes the antimicrobial activity of the aqueous individual plant extracts. Table 4a shows antibacterial efficiency for Sta. jamaicensis (B-W) and Bid. alba (A-W). Stem. maritima (D1-W) exhibits higher antibacterial efficiency compared to B-W and A-W.

(69) All the following combinations (1:1 mixture) of the aqueous extracts exhibit the same efficiency against gram-positive bacteria with MIC2/2 and MBC2/2:

(70) A-W/B-W, A-W/CW, BW/CW, CW/D1-W, BW/D1-W, A-W/D1-W, A-W/D2,

(71) B-W/D2, C-W/D2, D1-W/D2

(72) Table 5a summarizes the antimicrobial activity of the ethanolic extracts and Table 5b the combinations of the ethanolic plant extracts. The experiments clearly prove an antibacterial efficiency of Sta. jamaicensis and Bid. alba as well as of Stem. maritima. In particular, the afore-mentioned species exhibit significant efficiency against gram-positive bacteria and particularly against MRSA.

(115) The % by weight information in Table 6 is based on the dry weight of the extracts obtained according to Example 3 or 4, preferably according to Example 4.

(116) Depending on the desired indication of the skin, the pH value of the afore-mentioned tinctures 44 to 53 was set to:

(117) (a) tincture for the skin: pH 4.5 to 5.5

(118) (b) tincture for the oral mucosa: pH 6.7 to 7.2

(119) (c) tincture for the eye: pH 7.0 to 7.5

(120) (d) tincture for the nasal mucosa: pH 5.5 to 6.5

(121) (e) tincture for ears: pH 5.5 to 6.1

(122) The afore-mentioned mixtures and % by weight ratios (Table 6) may vary depending on the indication. For example, in the case where strengthened antimicrobial effect is desired, e.g. in the case of bacterial infections of the (mucous membrane) skin or in the mouth (gums), it is advantageous according to the invention to combine the extracts (or dry extracts) having the strongest antimicrobial effects (Table 5a/5b), or to use only one extract, e.g. A-E, (e.g. mixture 52 or 53). In contrast, in the case of strong inflammation, e.g. eye or ear, it may advantageous according to the invention to increase the content of particularly anti-inflammatorily effective extracts, e.g. A-E and/or C-E (Table 2 and 3). In this case, e.g. mixture 45 or mixture 45 having increased % by weight of each 5-20% by weight of the respective dry extract would be conceivable. In the case of antimicrobial ant anti-inflammatory indication at the same time, the appropriate combination according to the invention is to be chosen depending on the therapeutic goal.
