Pharmacognostic Parameters of Eucalyptus globulus Leaves

Abstract

Introduction: Eucalyptus globulus Labill synonym blue gum tree (Family: Myrtaceae) is an evergreen tree, one of the most widely cultivated trees native to Australia, South Africa, India and Southern Europe. The bark was used against toothaches and gum aches.The leaves were used against headaches which occured on one side of the head. Eucalyptus globulus Labill synonym blue gum tree (Family: Myrtaceae) possess antidiabetic, anti-inflammatory, antibacterial, antimalarial and Antioxidant properties. Methods: The present study will assist in standardization parameters like morphological characters, microscopic evaluation, physicochemical evaluations (loss on drying, ash values, extractive values), preliminary phytochemical screening and TLC chromatographic profile of the extract were carried out and the quantitative parameters were reported. Results: Chief macroscopic and microscopic characters include lamina with secretory cavity. Lower palisade cells, Lateral vein, secretory cavity, Spongy mesophyll, Upper palisade, stomata and with terminal clusters of sclereids. Conclusion: These studies provide referential information for correct identification and standardization of this plant material.

Phytochemical and pharmacognostic evaluation of leaves of Pongamia pinnata L. (Fabaceae)

“…There are many reports in the literature where pharmacognostic study of leaves of different plants is reported eg. Melaleuca leucadendron [27] , Nelumbo nucifera, [28] Manilkara zapota, [29] Eucalyptus globulus, [30] Cinnamomum verum, [31] Terminalia catappa, [32] Psidium guajava [33] and Polyalthia longifolia. [34] In conclusion, these parameters are reported for the first time for P. pinnata leaf.…”

Recovery of Iron Nanoparticles from Mine Wastewater Using Plant Extracts of Eucalyptus Globulus, Callistemon Viminalis and Persea Americana

“…These results can further be confirmed by using HPLC/GC-MS to understand the peak variation of each plant extract and its chemicals constitution prior to describing the reaction of the Fe from the mixture of MW and plant extracts. Polyphenols have been reported by several studies as common bioactive compounds occurring in many plants, such as EG, CV and AS extracts [46][47][48][49].…”
