Abstract: Medicinal plants play an important role in disease management and livelihoods of people worldwide. In recent years, the growing demand for medicinal plants has accelerated overexploitation of valuable resources by unscientific and destructive manner without considering sustainability and quality issues. As a consequence, the quality of both raw material and finished products has become important concern for herbal/pharmaceutical/nutraceutical/cosmeceutical industries and the public alike. Moreover, medicinal plant collectors are not getting remunerative value for their produce because of poor quality (due to wrong identification, immature collection, poor processing, inadequate storage, adulteration etc.). Good collection/harvesting practices of some important medicinal plants i.e., Aonla (Phyllanthus emblica), Baividang (Embelia tsjeriam-cottam), Baheda (Terminalia bellerica), Gudmar (Gymnema sylvestre), Sarpagandha (Rauvolfia serpentina) and Kalmegh (Andrographis paniculata) have been standardized for tropical climate of central India. The quality (active ingredients) of above plants was also evaluated. It is evident from our study that the medicinal plants harvested at right time of maturity following Good Field Collection Practices (GFCPs) possess better quality in terms of active ingredients concentration. Adoption of GFCPs and quality evaluation of medicinal plants will have positive impact on resource conservation, socio-economic status of community, quality of produce, economic returns and marketing. To achieve these, R and D institutions may act as nodal centers for quality evaluation and dissemination of GFCPs to the collector/growers of medicinal plants to augment utilization and get premium price of their produce.
