Formulation and Evaluation of Herbal Tablets and Hard Capsules Containing Urtica dioica Soft Extract”

摘要

The most important sorts of contaminant in the environment are heavy metals. Several methods are there for the removal of heavy metals in the environment, but most of them are costly and difficult to get optimum results. Currently, microwave assisted digestion process for the extraction of plant extracts is an effective and affordable technological solution which used to extract and then further removal of inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective. In the present study, the presence of heavy metals such as Lead, Zinc, Cadmium, Manganese and Magnesium were quantitatively estimated from the leaf part of the Salvinia molesta. These heavy metals were analyzed using Atomic absorption spectrophotometry (AAS). The obtained results revealed that the content of heavy metals (less than 10ppm) was within the permissible levels, except cadmium and lead. The results revealed that Salvinia molesta can grow healthy with the accumulation of these metals. Further this plant material can be used for the production of biodiesel.
