Comparative Pharmacognostic and Phytochemical Analysis of Three Market Samples of Rasna: Pluchea lanceolata, Alpinia officinarum, and Alpinia calcarata

Introduction: Ayurveda, an ancient system of medicine, utilizes a vast array of medicinal plants, each offering unique therapeutic properties that contribute to holistic health and well-being. However, misidentification of species is most common which comes in the way of authenticity. To cite an example - Pluchea lanceolata when mixed with varieties of Alpinia can lead to inconsistencies in their medicinal use. This underscores the need for accurate identification and standardization to ensure the efficacy of treatments and the safety of stakeholders. This research paper explores the botanical and medicinal profiles of Pluchea lanceolata, Alpinia calcarata, and Alpinia officinarum, emphasizing the importance of proper classification and the need for quality control in Ayurvedic herbal remedies. Materials and Methods: Raw materials were collected from Thrissur market and organoleptic, pharmacognostic and phytochemical analysis were done. Results and Discussion: Three varieties of Rasna (Pluchea lanceolata, Alpinia calcarata, and Alpinia officinarum) share common physical characteristics, such as scaly, rough rhizomes that are fibrous and tough, making them suitable for drying, grinding, or slicing (for medicinal use.) All three species exhibit starch grains, fibers, and stone cells in their rhizomes, contributing to energy storage, structural support, and resilience. Pluchea lanceolata has the highest total ash content, indicating a richer mineral composition, while A. calcarata and A. officinarum show lower mineral content. All three species contain phenols, sugars, carbohydrates, flavonoids, glycosides, steroids, and other bioactive compounds, contributing to their therapeutic properties. Conclusion: Standardization in preparation and use of Ayurvedic remedies is critical for preserving the integrity of Ayurveda, ensuring reliable therapeutic benefits, and positioning Ayurvedic medicine as a credible and effective global health solution.
