Dissertation Research Project
A Study on Frequently Used Medicinal Plant Leaves in the Village Area of Jamuhandal of Hojai District and Their Phytochemical Analysis
A field-based survey (April–June 2025) of five medicinal plants commonly used by residents of Jamuhandal village, Hojai district, Assam — Neem, Lemon, Sajona (Moringa), Creeping Woodsorrel, and Thankuni (Centella asiatica) — followed by qualitative phytochemical screening of their aqueous leaf extracts.
Problem & Scientific Objective
Rural communities in North-East India, including Jamuhandal, rely heavily on locally available medicinal plants for primary healthcare, yet the specific phytochemical constituents responsible for their therapeutic properties are often undocumented for these particular local specimens.
Analytical Methodology
- 1Ethnobotanical field survey (April–June 2025) with local residents and traditional healers to identify frequently used medicinal plants; herbarium preparation and identification with the Department of Botany, RTU.
- 2Leaves washed, shade-dried under pressure for 2 weeks, and ground to a powder using a mortar/electric blender.
- 3Aqueous extraction: 5 g of powdered sample soaked in 100 ml distilled water for 72 hours, filtered through Whatman filter paper, then centrifuged to obtain a clear extract.
- 4Qualitative phytochemical screening of each extract: chloroform/conc. H2SO4 test for steroids, 1% lead acetate test for tannins, froth test for saponins, dilute NH3/conc. H2SO4 test for flavonoids, and Wagner's reagent test for alkaloids.
Key Findings & Outcomes
Steroids and saponins were present in the aqueous extracts of all five plants (Neem, Lemon, Sajona, Creeping Woodsorrel, Thankuni).
Tannins were detected only in Neem; flavonoids were present in Neem, Creeping Woodsorrel, and Thankuni, but absent in Lemon and Sajona.
Alkaloids were absent (no red precipitate with Wagner's reagent) across all five plant samples tested.
