    Objective: Nowadays medicinal plants have been considered as complementary medicine in cancer treatment by many researchers. Osteosarcoma, one of the most common malignant tumors, which is more common at a young age; It is one of the most common types of cancer that occur in mesenchymal bone-forming cells and affect the musculoskeletal system. Today instead of cancer drugs due to their numerous side effects that can suppress or prevent cancer treatment, food supplement products that contain plant extracts may be preferred. In this study, the anticancer effects of five different food supplements were investigated on osteosarcoma Saos-2 cancer cell line. Material-Method: Application doses were as 1000, 2000, 3000, 4000, 5000, 6000 µg/ml and IC50 values were calculated by creating two working groups of 24 and 48 hours. Results: Extracts of five different herbal product showed cytotoxic effect on Saos-2 cancer cell line due to their mixture of medicinal plants, however REGULIN® showed the most cytotoxic effect among them.Conclusion: It was determined that REGULIN® used in the remember regeneration therapy method (RTM), had the most anticancer effect in each of the 24 and 48 hour application groups. Cytotoxic effect of these food products on other cancer cell lines and their use in the pharmaceutical and health industries is recommended in future studies.

    Background: Osteosarcoma; is one of the most common malignant tumors. Nowadays, because of the many side effects of cancer drugs, the usage of herbal medicine which can inhibit or eliminate cancer cells by their antioxidant compounds is increased. Objectives: In the present study anticancer effect of Tilia dasystyla and Polygonatum orientale Desf different extracts on osteogenic sarcoma (Saos-2) cancer cell line was investigated and their polyphenolic compounds were identified by liquid chromatography-mass spectrometry (LC-MS) analysis. The cytotoxic effect of these extracts on Saos-2 cell line and identification of their phenolic compounds have not been reported so far. Methods: Cancer cell lines were provided from Department of Biological Sciences, Bursa University, Turkey. Different concentrations of the methanol, ethanol, and diluted water extracts (0.5 - 5 mg/mL) were tested on Saos-2 cell line. After 24, 48, and 72 hours, the cell viability was evaluated using 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. For the investigation of total phenolic compounds of T. dasystyla and P. orientale Desf extracts LC-MS method was applied. Results: According to the results diluted water extracts on the Saos-2 cancer cell line showed more cytotoxic effect than other solvents. The lowest IC50 value was 0.58 +/- 0.01 mg/mL within 72 hours belonged to T. dasystyla water extract. Conclusions: Tilia dasystyla and Polygonatum orientale Desf extracts contain some polyphenolic compounds which showed cytotoxic effect on Saos-2 cancer cell line. The full potential of these herbal extracts is yet to be realized by further studies on animal models and subsequent trials.
