Introduction to Terminalia neotaliala
Focus on cytotoxic and wound healing properties of leaves.
2
Pharmacognostic Profile Overview
- Botanical name: Terminalia neotaliala, family Combretaceae.
- Leaves: simple, oblong-lanceolate, rich in tannins and flavonoids.
- Traditional uses include hypertension and wound healing.
3
Aims and Objectives
- Explore phytochemical composition of T. neotaliala leaves.
- Investigate antioxidant, cytotoxic, and wound healing properties.
- Validate traditional medicinal uses with scientific evidence.
4
Rationale of the Study
- Leaves and bark studied; other parts largely unexplored.
- Lack of in vivo validation and mechanistic understanding.
- No standardized extraction or comprehensive pharmacognostic data.
5
Hypothesis & Expected Outcomes
- Bioactive compounds in leaves responsible for medicinal effects.
- Identification of active fractions for future drug discovery.
- Preliminary in vivo evidence for cytotoxicity and wound healing.
6
Methodology: Extraction & Fractionation
- Fresh leaves macerated in methanol for crude extract.
- Fractionation into water, ethyl acetate, chloroform, hexane.
- Targeted bioactivity studies based on polarity.
7
Chemical Investigation
- Phytochemical screening for alkaloids, flavonoids, phenols.
- TLC/HPTLC fingerprinting and LC-MS profiling.
- Antioxidant assays: DPPH, ABTS, FRAP, CUPRAC.
8
Biological Investigation
- Cytotoxic activity via brine shrimp lethality/MTT assay.
- Anti-inflammatory activity using carrageenan-induced edema.
- Wound healing tested with excision/incision models.
9
Expected Contributions
- Comprehensive chemical profiling of T. neotaliala leaves.
- Validation of ethnopharmacological claims with evidence.
- Support for future in vivo and clinical studies.
