The Hydro alcoholic extract of Cleome rutidosperma (HAECR) leaf was analyzed by gas chromatography-mass spectrometry (GC-MS). The anatomical, physicochemical, and pharmacognostic properties of the extract were analyzed. The results showed that the leaves of HAECR exhibit organoleptic and macroscopical characteristics, showing distinctive features that enhance its taxonomic profile. The powder microscopy of the leaf reveals key microscopic features, including epidermal cell density, stomatal density, palisade ratio, and vein structure. The fluorescence analysis of the powder under visible, short-wave, and long-wave UV light revealed distinct color reactions with various reagents. The physiochemical constants of leaf powder reveals several important quality parameters. The Thin Layer Chromatography (TLC) analysis revealed a diverse composition of bioactive compounds, evident from distinct retention factor (Rf) values, spot colors, and varied mobile phases. These findings establish a foundation for further exploration of phytochemicals in medicinal plants, which are known for their therapeutic potential, reinforcing the value of TLC as a tool for the identification and characterizing bioactive constituents.

This study investigates the pharmacognostic and phytochemical properties of Anisomeles malabarica, a medicinal plant from the Lamiaceae family. A comprehensive analysis was performed, encompassing macroscopic, microscopic, and numerical taxonomic studies. The anatomical observations revealed distinctive traits such as unicellular trichomes, collenchymatous and parenchymatous ground tissue, and vascular bundles with concentric arrangements. Quantitative microscopy parameters, including stomatal index and vein islet number, were documented. Physiochemical analyses showed values within Ayurvedic pharmacopeia standards, ensuring the plant's purity and quality. The presence of essential inorganic elements like calcium, potassium, and iron was confirmed, with no detection of toxic heavy metals, underscoring its safety for medicinal use. DNA barcoding validated the species identity, enhancing its taxonomic classification. These findings highlight A. malabarica's potential for therapeutic applications and its importance in pharmacognostic standardization.

This study investigates the pharmacognostic characteristics of Averrhoa bilimbi leaves, encompassing macro and microscopic examinations, quantitative microscopy, and physicochemical analyses. Fresh and dried leaves were subjected to macroscopic evaluation to document their morphological features. Microscopic analysis revealed the presence of various cellular structures, including stomata, trichomes, and vascular bundles, which were examined in detail. Quantitative microscopy provided stomatal density, and other pertinent parameters, contributing to a comprehensive understanding of the leaf’s anatomical traits. Additionally, physicochemical studies assessed parameters such as moisture content, ash value, extractive value, and flow properties of leaf powder ensuring a thorough characterization of the leaf material. The findings underscore the significance of Averrhoa bilimbi leaves in traditional medicine and their potential as a source of bioactive compounds, paving the way for further pharmacological research.
