Evaluation of influence of Rutu (Seasons) on quality of Haridra (Curcuma longa Linn.) by pharmacopoeial tests and HPTLC fingerprinting
Journal Title: Journal of Ayurvedic and Herbal Medicine - Year 2016, Vol 2, Issue 1
Abstract
Medicinal herbs are to be harvested during their optimal season to obtain herbal products of the best possible quality. In the criteria for standardization, season of collection of the used part of a plant plays an important role to assure the quality of the drug. Ayurvedic classics have advocated certain season for the collection of used parts of the medicinal plants. Haridra kanda (rhizome of Curcuma longa Linn.) has wide range of applications as antioxidant, antiinflammatory, anti diabetic, anticarcinogenic, hypocholesterolemic, wound healing, antitumor and hepatoprotective agent. It is one of the important drug in Ayurveda used therapeutically in charmadosa, prameha, raktavikara, sotha, pandu, vrana etc. This study was carried out to evaluate the effect of sangraha kala (seasons of collection) of Haridra on quality indicating Pharmacopoeial constants. Haridra was cultivated and collected at different seasons and the procured rhizomes were powdered and subjected to qualitative and quantitative analysis. Macroscopic, microscopic, physicochemical, solvent extraction and chromatographic studies carried out suggest that Haridra collected during Sharad rutu (autumn season) contain more active principles to meet Pharmacopoeial requirements. It may be concluded that Sharad rutu is the ideal season for collection of Haridra rhizomes, which revalidates the classical reference in ancient Ayurvedic texts.
