ABSTRACT
INTRODUCTION: Rotheca serrata (Lamiaceae), a highly medicinal plant is used as an antidote for snakebite and the plant possesses medicinal properties like hepatoprotective, antitussive, antioxidant, anticancer, neuro-protective, used in rheumatoid arthritis and is also a α-glucoside inhibitor. AIM OF THE STUDY: This work aimed to study the anticancerous effect of Rotheca serrata (root and leaf) on cancer cell lines MCF-7 (breast cancer cell line) and Neuroblastoma SH-SY5Y. MATERIALS AND METHODS: This investigation was a preliminary one which supported the retrospective and safe use of plants as described in Ayurveda. Dulbecco's Modified Eagle Medium with High Glucose (DMEM-HG) for culturing MCF-7- Human Breast cancer cell line and Minimum essential Medium (MEM)+F12 medium for culturing SH-SY5Y- Homo sapiens bone marrow neuroblast were used. MTT assay measured the cell proliferation rate and conversely, when metabolic events lead to apoptosis or necrosis, the reduction in cell viability. RESULTS: The results indicated that the Methanolic extract of Rotheca serrata (root and leaf) showed high anticancer activity. Different concentrations of plant extracts (25, 50, 100, 200, 400 µg/ml) were used to study the anticancerous activity, amongst which the significant results were obtained for 400 µg/ml concentration (both root & leaf). Effective anticancer activity against MCF - 7 breast cancer cells was shown in methanoilc extracts and were expressed as IC 50 values; in root (IC 50 value = 61.8259 ± 7.428 µg/ml) and in leaf (IC 50 value = 78.1497 ± 6.316 µg/ml). The MTT assay in case of neuroblastoma (SH-SY5Y) cell lines revealed that 400 µg/ml concentration of leaf methanolic extract showed effective inhibition of cancer cells with IC 50 value 37.8462 ± 2.957 µg/ml as compared to IC 50 value of root methanolic extract which was 57.0895 ± 2.351 µg/ml. CONCLUSION: R. serrata possess anticancer activity against breast cancer cell line (MCF-7) and neuroblastoma (SH-SY 5Y) cell lines. This study may to design plant-based drugs without side effects. Dosage compensation for specific type of cancer needs to be monitored in patients with 1st stage.
