Materials & Methods:
This chapter meticulously recounts the tools and techniques employed to unlock the secrets of Paschim Medinipur's flora.From selecting the research sites to analyzing the extracted compounds, every step was meticulously designed in the past to ensure accuracy and reproducibility.

Study Site Selection:
Three distinct ecological zones within Paschim Medinipur were chosen for this study: 1.The Jhargram hills, nestled amidst diverse medicinal plants.2. The coastal plains near Digha, once teeming with halophytes boasting unique adaptations.

The agricultural heartland, once cultivating plants with promising nutritional and medicinal value.
Within each zone, specific sites were carefully chosen based on soil type, vegetation cover, and traditional knowledge passed down generations about plant usage.

Plant Selection:
A blend of ethnobotanical wisdom and scientific evidence guided the selection of 15 plant species (Table 01).Local healers and communities generously shared their insights into plants used for various ailments, while published research on individual species further informed the decision process.The chosen plants, now carefully catalogued in a permanent record, represent a diverse array of families, growth forms, and traditional uses.

Research Design:
This study employed a descriptive cross-sectional design.Samples of each plant species were collected during their peak season, when the concentration of bioactive compounds was at its optimal level.Three independent replicates were collected from each site, meticulously accounting for natural variations.Voucher specimens were prepared and deposited in the herbarium of department of Botany, YBN University, Ranchi, a testament to the research and a valuable resource for future reference.

Sample Preparation and Extraction:
Harvested plant parts, whether leaves, stems, flowers, or fruits, were thoroughly washed, dried in a wellventilated oven at 40°C, and pulverized into fine powder using a mortar and pestle or a grinder.• DPPH radical scavenging assay: This spectrophotometric assay measured the ability of plant extracts, now mere concentrates, to scavenge the stable free radical DPPH.The decrease in absorbance at 517 nm provided a quantitative measure of the antioxidant activity within each extract (Table 02).• ABTS radical scavenging assay: Similar to DPPH, this assay employed the ABTS+ radical and measured its reduction by plant extracts, reflecting their antioxidant capacity (Table 03).• Ferric reducing antioxidant power (FRAP) assay: This assay analyzed the ability of plant extracts to reduce Fe3+ ions to Fe2+ ions, signifying their reducing power and potential antioxidant activity (Table 04).

Phytochemical Profiling:
Total phenolic content (TPC) determination: The Folin-Ciocalteu reagent colorimetric assay, a wellestablished method, estimated the total phenolic content in plant extracts, providing an indication of their antioxidant potential (Table 05).

Data Collection and Analysis:
Each assay was meticulously performed in triplicate, and mean values with standard deviations were calculated.Statistical analysis using one-way ANOVA test was employed to compare antioxidant activity and phytochemical content between different plant species and ecological zones, revealing patterns and insights.

Methodology and Procedures:
Detailed protocols for sample preparation, extraction, and each assay were documented following standard laboratory practices.This meticulous approach ensures data integrity and allows for the replication of our research by other scientists, furthering the understanding of Paschim Medinipur's botanical treasures.

Ethical Considerations:
Prior informed consent was obtained from local communities before collecting plant samples.Sustainable harvesting practices were followed throughout the research process, minimizing ecological impact and ensuring the continued prosperity of the region's unique flora.

Results & Discussion:
This chapter unravels the tapestry woven by our research, interpreting the observed results to illuminate the antioxidant and phytochemical potential of Paschim Medinipur's flora.

Antioxidant Activity:
The DPPH, ABTS, and FRAP assays painted a fascinating picture of varied antioxidant capacities across the 15 chosen plants.Species like Emblica officinalis Gaertn.from the Jhargram hills emerged as champions, exhibiting potent free radical scavenging activity in all assays.In contrast, certain coastal halophytes from Digha, like Curcuma longa L. surprisingly displayed lower antioxidant activity, possibly due to adaptations for salt stress.The observed variations within and between ecological zones suggest a complex interplay of environmental factors and plant physiology in shaping antioxidant potential.

Phytochemical Profiling:
The total phenolic content (TPC) analysis confirmed the link between phenolic abundance and antioxidant activity.Plants with high TPC values, like Emblica officinalis Gaertn.also demonstrated strong free radical scavenging abilities.Specific flavonoids and phenolic acids were identified and quantified, revealing unique profiles for each species.Interestingly, some seemingly inconspicuous plants, like Curcuma longa L. harbored surprisingly high levels of specific bioactive compounds, highlighting the potential for overlooked treasure troves within the local flora.

Ecological and Ethnobotanical Correlations:
Intriguing patterns emerged when comparing antioxidant activity and phytochemical profiles with ecological zones and traditional uses.Plants from the Jhargram hills, traditionally known for their medicinal properties, often displayed significant antioxidant capacity and diverse phenolic profiles.Alpinia galanga (L.) Willd.Zingiberaceae 67.9 ± 2.2 This supports the wisdom of local communities in harnessing the natural health benefits of these plants.
On the other hand, some coastal halophytes, while exhibiting lower antioxidant activity in vitro, might possess unique adaptations for scavenging reactive oxygen species in their harsh environment, warranting further investigation.
