Background: Medicinal plants are a crucial source of therapeutic agents for treating various human ailments. Justicia tranquebariensis, a small woody shrub widely distributed in southern India is traditionally used for managing conditions such as respiratory problems, kidney infections, gastrointestinal diseases, anemia and more. Despite its extensive use in traditional medicine, detailed pharmacognostic studies on this plant are limited. Materials and Methods: Sections were prepared using a rotary microtome and histochemical analysis was conducted following standard protocols. Results: The macroscopical, microscopical and histochemical studies revealed the occurrence of key phytochemicals such as carbohydrates, proteins, lipids, alkaloids, flavonoids, tannins, phenols, starch and saponins. These findings contribute to the understanding of the plant{\textquoteright}s medicinal properties and provide a foundation for future pharmacological research.

Background: Ipomoea obscura, also known as {\textquotedblleft}Lakshmanvel{\textquotedblright} in India, is a member of the Convolvulaceae family. Early studies were mostly concerned with early phytochemical analysis, with only a few focusing on detailed phytochemical analysis. Objectives: The aim of this study was to identify the phytochemical and pharmacognostic characteristics of I. obscura leaves. Materials and Procedures: The methanolic extracts were separated into flavonoids and phytosterol by column chromatography, which were subsequently examined by spectroscopy and HPTLC methods. Results: According to this research{\textquoteright}s findings, I. obscura leaves may be a good source of phytochemicals such flavonoids (Kaempferol and quercetin), terpenids (β-sitosterol and lupeol), which were identified by HPTLC fingerprinting, FTIR NMR, and UV spectroscopy. Conclusion: The spectroscopical data and HPTLC fingerprinting profile for the plant of interest would hopefully aid herbal medicine researchers in developing additional herbal medications that require the specific ingredient or extract.
