An article by Lewandowska U et al (Lewandowska U, szewczyk K, owczarek K, et al. Flavenols from Japanese clinic (Chaenomes japonica) from experiment in front of human and fresh cancer cell in vivo and fresh cancer cells in Bax/Bcl-2mRNA ratio J.Nutrition and cancer, 2013, 65 (2): 273-285.) reports that Flavanols extracted from Malus japonicus inhibit the invasiveness of human breast cancer and prostate cell carcinoma and improve the ratio of Bax and Bcl-2 mRNA. Chinese patent CN 201210547318.2 also discloses a new flavanol compound in the wild sweet bean, its preparation method and application, the flavanol compound is separated from the wild sweet bean, and has obvious anticancer and marine fouling organism resisting activity, and at the same time, has obvious inhibiting effect on tumor, human cervical carcinoma, human chronic myelogenous leukemia or human acute myelogenous leukemia cell. However, not all Flavanols have good antitumor activity, for example, studies by Williamson G et al (Williamson G, dionisi F, renouf M. Flavanols from green tea and phenolic acids from coffee. Critical cosmetic evaluation of the pharmacological data in human after consumption of simple doses of vitamins. Mol Nutr food.2011 55. Study by Nakai M et al (Nakai M. Fukui Y. Asamis S. Et al. Inherent efficacy of organic tea polysaccharides in vitamin catechin [ J ] J. Journal of Agricultural catechin, vitamin E. Epigallocatechin, (-3-4593. Epigallocatechin, (-) -3-4593-11. Epigallocatechin, (-) -3-4593-11) and various epigallocatechin gallate 3-459 3-53. Epigallocatechin, (-) -3-epigallocatechin, (-3-4593) 3-epigallocatechin, (-) -3-11. Epigallocatechin, (-) -epigallocatechin 3-gallate and epigallocatechin 3-4. Epigallocatechin, (-) -2,53, respectively, however, some of the flavanols in the above mentioned article have been found to have unsatisfactory antitumor activity against various tumor cell lines.
Anthraquinone compounds are chemical components with quinoid structures, and are widely distributed in plants such as polygonum multiflorum, cassia seeds, aloe and the like, and a plurality of antitumor drugs containing the anthraquinone structures, including daunorubicin, doxorubicin and mitoxantrone, are carried in newly-compiled pharmaceutics (17 th edition). Chinese patent CN 201810319871.8 also discloses anthraquinone compounds, which are natural products obtained by fermenting and purifying actinomycetes with rice, have obvious antitumor activity, especially have obvious proliferation inhibition effect on PC3 cells of human prostate cancer cell strains and SW620 cells of human colon cancer cell strains, and can be used for developing antitumor drugs. However, not all anthraquinones have a good antitumor activity, and for example, wu Xiaohui, in his Ph's Proc. Thesis on the chemical composition, quality control and in vivo metabolism of cassia seed [ D ]. Huazhong university of science and technology, 2010. Discloses various anthraquinones as active ingredients isolated and extracted from cassia seed, including the following compounds:
、、、、、、、、andand the like. However, it is found through experiments that some anthraquinone compounds in the above mentioned article have unsatisfactory antitumor activity for various tumor cell lines.
Aiming at the problem that part of flavanol compounds or anthraquinone compounds have poor antitumor activity on various tumor cell strains, a composition is found by combining the respective advantages of the two compounds, so that the two compounds cooperate to promote the antitumor activity.

MTT method is adopted to determine the effect of the antitumor drugs prepared by the compounds in the example groups 1-100, the comparative examples 1-20 and the comparative example groups 21-22 on the proliferation of various tumor cells. Taking liver cancer HepG2 cell as an example, the liver cancer HepG2 cell is recovered to RPMI1640 culture solution containing 10% fetal bovine serum, and is cultured for 24h in an incubator with the concentration of 5% CO2 at 37 ℃; setting blank group (without cell, culture solution and without drug), control group (with cell, culture solution and without drug) and example drug-adding group (with cell, culture solution and drug in example groups 1-100) as shown in Table 1 and comparative drug-adding group (with cell, culture solution and drug in comparative examples 1-20 and comparative examples 21-22) as shown in Table 1 and Table 2, digesting the cells from the culture dish by pancreatin and re-inoculating the cells into 96-well plate to make the number of cells per well of the control group and drug-adding group be 1X 10 3 -1×10 4 37 ℃ and 5% CO 2 Culturing for 24h, adding drug-containing RPMI1640 culture solution 200 μ L shown in Table 1 and Table 2, adding drug-free RPMI1640 culture solution 200 μ L into control group and blank group, each group having 6 parallel wells, culturing for 12h, adding 5mg/mLMTT20 μ L into each well, culturing for 4h, removing supernatant, adding 100 μ LDMSO dissolved sample into each well, and measuring the concentration of each well at 490nm with microplate readerAnd (4) light absorption value. The mean of the absorbance values of 6 wells was taken, and the Inhibition Rate (IR) = (1-mean absorbance for drug addition group/mean absorbance for group) × 100% was calculated according to the formula.
Plotting the Inhibition (IR) against the log of the drug concentration (. Mu.M), linear regression with Excel, and calculating the concentrations of the chromanol derivatives and anthraquinones, IC, respectively, at the time of occurrence of the specific inhibitory effect (fa) according to the regression equation fa (A) And IC fa (B) The value is obtained. For the combination, inhibition Ratio (IR) was plotted against log (c) of the concentration (. Mu.M) of the chromanol derivative in the combination (log (c)), and linear regression was performed using Excel to calculate the concentration of the chromanol derivative in the combination system at the time of fa inhibition, i.e., IC, based on the regression equation fa(mixA) Then, the concentration of the anthraquinone compound in the combination system, i.e. IC, is calculated according to the molar ratio of the benzo-hydropyranol derivative to the anthraquinone compound in the combination system fa(mixB) 。
According to the following formula, the combination of the benzo-hydropyranol derivative and the anthraquinone compound for inhibiting the HepG2 cell of the liver cancer is calculated
The interaction index CI.
When CI <1, synergy is indicated, and smaller CI indicates greater synergy.
The inhibition rate of the chromanol derivatives and the anthraquinones to other tumor cells was determined by the same overall method, and the CI value was calculated based on the results, and the results are shown in table 1.
TABLE 1 test results of liver cancer HepG2 cells
The average CI values at different molar ratios in example groups 1 to 100 and comparative example groups 21 to 22 were calculated to obtain Table 2.
TABLE 2 mean CI values for compositions of different molar ratios
As can be seen from the test results of the HEPG2 cells of the example groups 1-100 and the comparative examples 1-20 in Table 1, the highest inhibition rate of the drug on the liver cancer HepG2 cells in each example group is 70-90%, and the highest inhibition rate of the drug on the liver cancer HepG2 cells in each comparative example group is less than 50%, which indicates that the drug in the example group has a good inhibition effect on the liver cancer HepG2 cells. Meanwhile, as can be seen from the average CI values of the example groups 1 to 100 and the comparative example groups 21 to 22 in table 2, the CI values in the example groups were less than 1 in the range of 1 to 100.
