The applicant has done the test of flaccid anemone saponine anti-tumor:
Experiment 1, flaccid anemone saponin are to the anti-tumor activity of human cervical carcinoma cell strain HeLa
A. experimental technique
Human cervical carcinoma cell strain HeLa is adopted in this experiment, and the phase cell of taking the logarithm is made cell suspension, and being diluted to concentration is 2.5 * 10
3-50 * 10
3/ mL is inoculated in 96 well culture plates, every hole 200 μ L, and the 24h hypsokinesis goes out culture fluid, adding contains variable concentrations R1, the R2 substituent group is the culture fluid of the flaccid anemone saponin of 1-5, and final concentration is 50,20,5,0.5 μ mol/L adds PBS and be blank in culture fluid, every sample is all established 4 holes.Control wells and zeroing hole add 200 μ L culture fluid.24h adds MTT solution 20 μ L after dosing, continues to cultivate, and carefully removes culture fluid, adds 200 μ LDMSO, measures each hole A value on microplate reader, and the mensuration wavelength is 570nm.By formula suppression ratio (IR): IR (%)=(1-dosing holes average A value/control wells average A value) * 100% calculates suppression ratio.Draw amount effect curve according to the suppression ratio under the variable concentrations, calculate IC thus

Experimental result discloses each saponin demonstration and induces the HeLa Cells apoptotic effect, is the mechanism of action of its anti-tumor activity.
Fig. 2 shows that the flaccid anemone saponin is followed successively by R1, R2 substituent group 5 (F), 4 (E) to human cervical carcinoma cell HeLa apoptotic effect size,, 3 (D), 1 (B), 2 (C).
Experimental example 3, the influence that the flaccid anemone saponin is expressed human cervical carcinoma cell Caspase-3
A. experimental technique
Cell climbing sheet preparation: when the Hela cell covers with culture bottle 80%, clean reuse 0.25% trypsin room temperature digestion 2-3min with PBS, with softly piping and druming repeatedly of suction pipe, cell is dispelled, be inoculated in 6 orifice plates that preset coverslip, it is the saponin 1-5 of 50 μ g/mL that adherent back adds final concentration of cells, negative control group adds the equivalent solvent, take out coverslip behind the conventional cultivation 24h, fix, carry out cellular immunization with 4% Polyethylene Glycol, groupization dyeing detects the proteic expression of caspase-3.
Concrete steps: get fixed cell climbing sheet, wash 2 times with PBS, cold wind dries up; 0.1%Triton-X100 is hatched 1 time, and wash 3 times with PBS the back; 3%H
2O
2Hatch with the blocking-up endogenous peroxydase, PBS shakes and washes 3 times afterwards; Drip normal goats serum confining liquid, in wet box, 37 ℃ of insulations to eliminate unspecific staining, discard unnecessary liquid, do not wash;
Drip one anti-(caspase-3 rat IgG) of dilution in 1: 100, in wet box, 4 ℃ are spent the night, and PBS shakes and washes 3 times, each 3min; Drip the anti-IgG of biotinylated goat, in wet box, 37 ℃ of insulations, PBS shakes and washes 3 times; Drip reagent SABC, in wet box, 37 ℃ of insulations, PBS shakes and washes 3 times;
DAB dyeing: use DAB colour reagent box, get the 1ml distilled water, add each one of A in the test kit, B, C reagent, add to coverslip behind the mixing, color development at room temperature, mirror is the control reaction down, back distillation washing 2 times;
Haematoxylin is redyed (the nucleus lining dyes): immerse brazilwood extract dyeing liquid, and washing from the beginning, the persalt alcoholic solution is to break up multiple indigo plant, washing rapidly;
Dehydration step by step: cross 75%, 95%, 100% dehydrated alcohol;
Transparent: as to cross xylene solution 3 times;
Mounting: will have one of cell to face down, and use the resinene mounting.
Microscopically is observed: every smear is got 10 visuals field at random, 300~500 cells of each visual field counting.Count Caspase-3 immuning positive cell number and negative cells number respectively, carry out statistical analysis.Pale brown color or brown occurring in cell membrane and cytoplasm, to be that Caspase-3 expresses positive, and nucleus is dyed blue color.
B. experimental result sees Table 3 and shown in Figure 3, and experimental result discloses each saponin demonstration and induces HeLa Cells caspase-3 high expressed, and further conclusive evidence is that the mechanism of action of its anti-tumor activity is apoptosis-induced effect.
