Herbal medicines are in great demand over the world for primary health care because of their efficacy, safety and lesser side effects. Traditional use of medicines is recognized as a way to potential future medicines. Of the top 34 top marketed drugs for different diseases, 14 are natural compounds and natural products are main sources of anticancer agents. There are several higher plant species that need to be explored as a source of anticancer agents.
The recent great advances in medical treatment and scientific technology include many anticancer agents. The search for new anticancer agents focuses on not only synthetic compounds, but also natural products. This thesis is an approach to identify new lead molecules from the natural sources against breast cancer. Guided by the folklore knowledge, Tabernaemontana divaricata was chosen as the plant for study.
This plant is explored as per literature, and studied with regard to its phytochemical and pharmacological activities. The work has been focused towards isolation and characterization of the phytoconstituents from the leaves of the plant, which can show potent inhibitory activity against proliferation of breast cancer, and also act as novel lead molecule for development of potent anticancer drug/agent.

Excerpt from the Book
CANCER
Cancer is abnormal growth of cells generally called as malignancy.
There are different types of cancer, ranging over 100.
Reasons of cancer: mutation and abnormal activation of genes
Only a small fraction of mutated genes can develop into cancer. (Guyton and Hall)
Main reason of mutation
Radiations
Chemical irritants
Hereditary factors
Viruses

Frequently Asked Questions
What is the primary scope of this research?
The research focuses on the scientific exploration of the plant Tabernaemontana divaricata to determine its potential as a natural source for anticancer agents, particularly against breast cancer.
What are the central thematic fields covered in this study?
The study integrates molecular docking (in silico analysis), phytochemical isolation and characterization, and pharmacological testing (in vitro and in vivo models).
What is the main objective or research question?
The main objective is to identify the most potent extract from Tabernaemontana divaricata leaves that exhibits anticancer activity against the MCF-7 breast cancer cell line and to characterize the active chemical constituents.
Which scientific methods were employed?
The study uses standard phytochemical extraction, column chromatography, spectral analysis (UV, FT-IR, NMR, MS), DPPH assays for antioxidant capacity, SRB assays for anticancer activity, and computational docking software (Maestro, Lead IT, Autodock).
What is treated in the main part of the work?
The main body of the work covers the systematic identification of active compounds, their binding affinities through docking, and the subsequent biological assessment of their antioxidant and antiproliferative effects.
Which keywords best characterize this publication?
The most important keywords include Tabernaemontana divaricata, breast cancer (MCF-7), phytoconstituents, molecular docking, and pharmacological evaluation.
What were the findings regarding Compound 1?
Compound 1 was successfully isolated and characterized via spectral studies as a heptamethyl-hexadecahydropicen-derivative, though it was found to be ineffective against breast cancer in the performed tests.
What was the conclusion regarding the plant extracts?
While the specific isolated compounds showed limited efficacy against breast cancer cells, the study concluded that the crude petroleum ether and chloroform extracts of Tabernaemontana divaricata possess significant effective anticancer properties.
