Abstract

Introduction: Ricinus communis Linn (Euphorbiaceae) commonly known as Eranda in Ayurveda is a soft-wooded small tree wide spread over tropics and warm temperate region of the world. Roots are said as Virshya, Vatahara and beneficial in various ailments. As per Dravyasamgrahanakaala roots are advised to collect in three seasons, Greeshma, Pravarut and Shishsira. With all these backgrounds, planned to conduct pharmacognostic study of roots collected in three seasons. Materials and Methods: Roots collected in above three seasons Greeshma, Pravarut and Shishsira are shade dried, labelled properly subjected for Macro- microscopy, Physico chemical standards, Phytochemical study and HPTLC as per standard guidelines. Results and Discussion: Macro-microscopic features have not shown much difference among their histological features. Physico chemical standards and HPTLC have shown standard values. The Phytoconstituents like Alkaloid, Steroid, Carbohydrates, Tannins, Coumarins shown thier presence in majority of all seasons. Similarly, the constituents like Resin, Amino acids, Carboxylic acids, Phenol, Tetrapenoids, Saponins, Flavanoids were absent in the all three seasons. Quinone as secondary metabolite found in two seasons. Conclusion: Dravyasamgrahana kala (instruction for collection) is a textual guideline documentary mentioned in Samhitaas till Nighantu period, wherein they have specified the specific kaala (season) for collection of different parts of plant. Pharmacognostical study conducted on these sample of Ernadamoola proved the ancient fact that there is a role of season on metabolites of drugs.
