Pharmacognostic and Physico- Chemical Evaluation of Leaves of Tecoma Gaudichaudi DC (Bignoniaceae).

Tecoma gaudichaudi DC (Family Bignoniaceae) is a small tree of height 9-12m. and various Tecoma species are attractive to bees, butterflies or birds. Present study focuses on determination of some quantitative microscopical factors of leaves of Tecoma gaudichaudi DC includes Stomatal no., vein islet no etc. Under physicochemical standards various parameters were checked, such as ash value, acid insoluble ash value and moisture content etc. It helps in to check purity of crude drug. Ultimately it helps in evaluation of crude drug and valuable addition of pharmacognostic data towards updating of monograph of plant species.
