ABSTRACT- OBJECTIVE: The study deals with the preliminary phytochemical screening, pharmacological evaluation, and
identification of bioactive compounds present in Commelina benghalensis using the GC-MS technique. The main objective of the work was to analyze the phytochemical constituent, conduct pharmacognostical studies, and identify biologically active compounds from the selected plant. METHOD: Fresh leaves of Commelina benghalensis were collected, shade-dried, and powdered into a coarse form. The powdered plant material was subjected to solvent extraction using ethanol and ethyl acetate. The obtained extract was then used for preliminary phytochemical screening to detect various secondary metabolites. Further analysis was carried out using GC-MS to identify the active phytochemical constituent present in the plant. RESULT: The results of the study emphasize the phytochemical and pharmacognostical importance of Commelina benghalensis and confirm the presence of several bioactive compounds identified through GC–MS analysis.
INTRODUCTION: Traditional medicine plays a vital role in healthcare systems worldwide. Human survival would be challenging without the widespread use of plants and plant-derived products. Since ancient times, people from diverse civilizations have relied on plants for the treatment of numerous ailments. The World Health Organization (WHO) defines a medicinal plant as a herbaceous species that possesses phytochemical compounds responsible for therapeutic activities. In recent years, there has been growing interest among scientists and healthcare professionals in medicinal plants following the validation of their therapeutic benefits. Comedian beng halensis is a medicinal herb that belongs to the family Commelinaceae. It is a perennial species indigenous to the tropical regions of Asia and Africa and is commonly referred to as Bengal dayflower or dew flower. The plant is a robust, spreading herb that grows annually and reaches a height of approximately 40 cm. Its roots emerge from the basal nodes. The species is readily recognized by its small, attractive bluish-violet flowers. The leaves are ovate to elliptical in shape, occasionally appearing slightly triangular, and are deep bright green in colour, measuring about 4–7 cm in length. The fruit capsules are broadly ovoid to oblong, approximately 4–5 mm long, while the seeds are ovoid in form. Traditional uses: In India, Commelina benghalensis is traditionally used to treat ailments such as headache, constipation, leprosy, fever, snakebite, jaundice, mouth thrush, insanity, epilepsy, and psychosis. It is also known for its anti-inflammatory, demulcent, emollient, and depressant properties. In Lesotho, the plant is used to manage infertility in women. In China, it is used as a diuretic. In Pakistan, it is employed in the treatment of leprosy and is also used as a laxative and anti-inflammatory agent. In Bangladesh, the plant is used to treat insomnia, cataracts, night blindness, and other eye disorders, as well as suppurative sores, snakebites, inflammation, burns, conjunctivitis, headaches, toothaches, and eczema.
