Isolation, characterization and in vitro cytotoxicity studies of bioactive compounds from Alseodaphne semecarpifolia Nees.

ABSTRACT: Alseodaphne semecarpifolia (Lauraceae) is a traditional medicinal plant historically used in Indian Western Ghats to treat various human diseases. From the past few decades it has been traditionally recognized as an effective agent in cancer treatment. The phytochemical investigation of the stem bark and leaves of A. semecarpifolia led to the isolation of bioactive flavonoid compounds Icariin and Baicalein. Their structures were elucidated from obtained spectral data (¹H NMR, ¹³C NMR, ¹H ¹H COSY, FTIR and MS). Cytotoxic activity of Icariin and Baicalein evaluated against MCF-7 cells revealed their potent activity with an IC₅₀ of 42.15 ± 4.78 μg/ml and 44.37 ± 3.46 μg/ml, respectively, while very least effect was observed on normal cells (L6). Present study has suggested that both Icariin and Baicalein have potent cytotoxic activity against MCF-7 cells.

Project description:Medicinal plants play important role in the public health sector worldwide. Natural products from medicinal plants are sources of unlimited opportunities for new drug leads because of their unique chemical diversity. Researchers have focused on exploring herbal products as potential sources for the treatment of cancer, cardiac and infectious diseases. Arisaema flavum (Forssk.) is an important medicinal plant found in the northwest Himalayan regions of Pakistan. It is a poisonous plant and is used as a remedy against snake bites and scorpion stings. In this study, two bioactive compounds were isolated from Arisaema flavum (Forssk.) and their anticancer activity was evaluated against human breast cancer cell line MCF-7 using an MTT assay. The crude extract of Arisaema flavum (Forssk.) was subjected to fractionation using different organic solvents in increasing order of polarity. The fraction indicating maximum activity was then taken for isolation of bioactive compounds using various chromatographic and spectroscopic techniques such as column chromatography, thin-layer chromatography (TLC), gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (NMR). Crude extract of Arisaema flavum (Forssk.), as well as various fractions extracted in different solvents such as n-hexane, chloroform and ethyl acetate, were tested against human breast cancer cell line MCF-7 using an MTT assay. The crude extract exhibited significant dose-dependent anticancer activity with a maximum activity of 78.6% at 500 µg/mL concentration. Two compounds, hexadecanoic acid ethyl ester with molecular formula C18H36O7 and molar mass 284 and 5-Oxo-19 propyl-docosanoic acid methyl ester with molecular formula C26H50O3 and molecular mass 410, were isolated from chloroform fraction. These compounds were tested against the MCF-7cell line for cytotoxic activity and exhibited a significant (p < 0.00l) decrease in cell numbers for MCF-7 cells with IC50 of 25 µM after 48 h of treatment. Results indicated that Arisaema flavum (Forssk.) possesses compounds with cytotoxic activity that can further be exploited to develop anticancer formulations.
