     Abstract Objective To investigate the solvent applanatum Ganoderma lucidum extract anti-cancer effects. Methods The

    system solvent from the tree to be a series of tongue-

    Ganoderma lucidum extract, using MTT method examined the extracts on cultured human breast cancer MCF-7 cell

    proliferation. The results of the chloroform extract on the

    proliferation of tumor cells significantly inhibited the remaining layers of the sample inhibition was not obvious. Conclusion applanatum anti-tumor constituents of Ganoderma

    lucidum may be part of the chloroform.

     Key words applanatum Ganoderma lucidum; chloroform extract;

     Study on Antitumor Action of Rude Extracts from Ganoderma lipsiense (Batsch) GF Atk. In vitro

     Abstract: ObjectiveTo investigate the in vitro antitumor action of the different extracts of different solvents from

    Ganoderma lipsiense. MethodsAll the extracts were obtained by the technology of solvent-refining, and MTT method was used to test the cytotoxicity of the extracts on breast cancer of MCF -7 cells.ResultsThe chloroform extract showed the significant antitumor action when compared with the controls, and the others did not show obvious antitumor action. ConclusionThe chloroform extract may contain antitumor components.

     Applanatum Ganoderma lucidum (Ganoderma lucidum flat cap, flat Ganoderma lucidum) Ganoderma lipsiense (Batsch) GF Atk of Ganoderma (Ganoderma Karst.) Fungi. Closely related species there are layers Diego Ganoderma lucidum Ganoderma lobatum (Schw.) Atk, a handle Ganoderma lucidum Ganoderma gibbosum

    (Nees) Pat, etc. [1]. Applanatum Ganoderma lucidum natured, slightly bitter flavor, for the treatment of hepatitis B, esophageal cancer and tuberculosis [2]. Applanatum anti-tumor

    activity of Ganoderma lucidum frequently reported [3], but

    more concentrated in water-soluble polysaccharides and other

    components. In this paper, MTT method [4] studied the tree tongue of the ethanol extract of Ganoderma lucidum, ether extract, ethyl acetate extract, chloroform extract and petroleum ether extract on human breast cancer cells (MCF-7)

    survival rate impact.

     1 Materials and methods

     1.1 medicinal tree tongue fungus, were purchased in Yanji City, Jilin Province, Chinese medicine medicine company, by Jilin Agricultural University, Institute of Tolgor professor of fungi identified as Ganoderma lipsiense (Batsch) GF Atk. Crushed, over 40 mesh sieve, spare.

     1.2 cell line of human breast cancer cells (MCF-7), were

    purchased in Jilin Province Tumor Hospital.

     1.3 Reagents RPMI 1640 medium (Gibco U.S. products), FCS (fetal calf serum, Hangzhou Sijiqing Biological Engineering Materials Co., Ltd. products), tetrazolium salt MTT (Sigma products), DMSO (dimethyl sulfoxide ), 95% ethanol, ethyl ether, n-butanol, ethyl acetate, chloroform, etc. (which are

    all made analytically pure).

     1.4 Instrument Rotary Evaporator, micro pipette, oscillators, microplate reader, CO2 incubator thermostat, clean benches, inverted microscopes, centrifuges, flasks, 96-

    well plate, liquid nitrogen tanks and so on.

     1.5 Methods using the system solvent for pre-meal after

    the extraction of Ganoderma lucidum tree tongue, vacuum

    concentrated extract, were alcohol, chloroform, ethyl ether, ethyl acetate and butanol extracts. Reposted elsewhere in the

     Experimental set reagent control group, tumor cells of various drug control group and test group. Use of culture in the logarithmic phase of MCF-7 cells, adjusting the cell

    concentration of 1 × 105 Ge / ml, 5 Zhong PDD subjects a

    final concentration of drugs for 500,100,50,25,12.5,6.25 and 3.125 μg / ml ,5-Fu final concentration of 25 μg / ml.

     Suspension of tumor cells obtained, each hole 100 μl,

    inoculated in 96-well culture plates, the next day plus

    subjects of drugs, each conga dose 100 μl, each dose of three

    parallel holes. 37 ?, 5% CO2 saturated humidity, 48 h after culture, and then supernatant after centrifugation of each conga MTT20 μl, cultured 4 h later, each well add 100 μl

    dimethyl sulfoxide (DMSO), micro-oscillator oscillation 5 min,

    measured on microplate reader set of holes in the absorbance value at 550 nm wavelength.

     Inhibition rate (%)=( 1-OD treatment group / OD control)

    × 100%

     2 Results

     Ganoderma applanatum sample pairs of the solvent layer of MCF-7 cell survival effects shown in Table 1 ~ 5.

     Table 1 applanatum chloroform extract of Ganoderma lucidum on MCF-7 cells, the inhibition rate (abbreviated)

     As can be seen from Table 1, the tree tongue chloroform

    extract of Ganoderma lucidum in vitro MCF-7 cells have a

    stronger inhibitory effect, when the drug concentration in 1:10 and 1:50 when the inhibition rate of up to 89.4% and 82.6%. In addition to chloroform layer, the remaining layers

    of sample pairs of MCF-7 cells had almost no inhibitory

    effect.

     3 Discussion

     In this paper, the tree was studied by MTT tongue of the ethanol extract of Ganoderma lucidum, ether extract, ethyl acetate extract, chloroform extract, petroleum ether extract in vitro on human breast cancer cells (MCF-7) of the survival

    rate of the impact. The results showed that chloroform extract of MCF-7 cells a strong inhibition, inhibition of the remaining layers of the sample was not obvious. Is actually out of control tumor cell proliferation, differentiation or cell abnormal loss, inhibit the proliferation of recycling is the treatment of cancer, reducing its metastasis and recurrence of the directions. Inhibit tumor cell proliferation to find a cheap and effective drugs is the current research

    focus. In this study the tree to find an effective anti-tumor

    effect of Ganoderma lucidum tongue position, tongue fungus on the tree-depth foundation for the development.
