Background: A number of nonsteroidal anti-inflammatory medications have been shown to lessen pain and inflammation. Unfortunately, there are numerous side effects connected with their use. There are, however, medicinal plants that have anti-inflammatory therapeutic effects with little to no side effects. Momordica dioica is a herb that belongs to the Cucurbitaceae family. There are numerous phytoconstituents in it. Ursolic acid is one of them and a pentacyclic terpenoid that is found in nature and has a number of therapeutic benefits. The current study looked at Ursolic Acid{\textquoteright}s activities (UA), a secondary plant metabolite, for its anti-inflammatory properties in the Momordica dioica plant. The current study{\textquoteright}s objective was to create and validate an HPTLC method that was quick, accurate, precise, and specific for determining ursolic acid from Momordica dioica herbal extract. Methodology/Conclusion/Significance: For quick analysis of Ursolic acid determination, The High Performance Thin Layer Chromatography (HPTLC) was established and confirmed. On an aluminium HPTLC plate (60 F254) coated with precoated silica gel with formic acid, ethyl acetate, and toluene (7:3:0,1), chromatographic separation was accomplished. The detection process was carried out at 530 nm. Ursolic acid{\textquoteright}s Rf value was discovered to be 0.795\%. In the 400ng/band concentration range, linearity for ursolic acid was detected. The limits of detection and quantitation for ursolic acid were observed to be 0.04 ng/ band and 0.14 ng/band, respectively. The mean \% recovery of rosmarinic acid was (0.54). The method{\textquoteright}s specificity, robustness, linearity, precision, and accuracy have all been validated in compliance with ICH standards. The created method can be used to evaluate the regularity of ursolic acid in herbal extracts.

Aim and Objectives: The exploitation, adulteration and substitution of herbs is major hurdle for development of commercial natural products. Thus, the microscopic evaluation is the first step towards standardization of medicinal plant. A leaf from Sansevieria cylindrica Bojer ex Hook is examined both macroscopically and microscopically in the current study. Materials and Methods: Sansevieria cylindrica Bojer ex Hook (Asparagaceae) is an indoor ornamental plant. Macroscopic characteristics viz. size and shape, colour, odour and taste were studied. Microscopic evaluations were performed by means of high-resolution microscope. Anatomy of the leaves was examined by following standard method of section cutting. Results: The macroscopic assessment showed that the plant leaves are light to dark green in colour having highly fibrous structure. Stomatal constants of 230, 19.6\% stomatal index, 53.34/mm2 vein islet number, and 79.12/mm2 vein termination number were noted in the leaves. Anomocytic stomata, unicellular trichomes, xylem fibres, oxalate crystals, vascular bundles, etc. were all revealed in detailed microscopy. Conclusion: The macroscopic and microscopic findings of the Sansevieria cylindrica leaf are applicable for standardization and authentication of plant.
