Phytochemical screening by FTIR spectroscopic analysis of leaf extracts of selected Indian Medicinal plants

A large number of medicinal plants are used as alternate medicine for diseases of man and other animals since most of them are without side effects when compared with synthetic drugs. Identification of the chemical nature of phytochemical compounds present in the medicinal plants will provide some information on the different functional groups responsible for their medicinal properties. While studying the in vitro efficacy of bioactive extracts of 15 medicinal plants against ES Lproducing multi drug resistant bacteria, Iqbal Ahamad et al. (2006) detected major groups of compounds as the most active fraction of four plants extracts by infrared spectroscopy. Ramamoorthi and Kannan (2007) screened the bioactive group of chemicals in the dry leaf powder of Calotropis gigantea by FTIR analysis.
