Aim: The study was aimed to evaluate the pharmacognostic features of Hemidesmus indicus, analyze the antibacterial properties of ethanolic and aqueous root extracts, and identify bioactive compounds using GC-MS analysis. Materials and Methods: We conducted pharmacognostic analyses, including organoleptic, macroscopic, microscopic, and physio-chemical evaluations, phytochemical screening, and fluorescence analysis. We also used standard protocols for TLC fingerprinting. Antibacterial activity against gram-negative bacteria was assessed using the agar well diffusion method. Additionally, we conducted GC-MS analysis to identify major compounds in the plant extracts. Results: In our H. indicus root examination, we identified three regions: wood, inner cortex, and outer phellem. Key findings: moisture content at 9.0\% w/w, ethanol and water-soluble extractives at 11.21\% and 16.89\% w/w, total ash at 4.21\% w/w, acid-insoluble ash at 1.14\% w/w, and water-soluble ash at 3.12\% w/w. Phytochemical screening detected alkaloids, flavonoids, tannins, polyphenols, triterpenoids, carbohydrates, and proteins. TLC analysis of the ethanolic extract showed varying Rf values. The aqueous extract exhibited stronger antibacterial activity against E. coli than the ethanolic extract. GC-MS analysis identified over 30 prominent compounds in the ethanolic extract. Conclusion: In conclusion, this study provides valuable insights for the standardization of H. indicus root extracts. The aqueous root extract displayed notable antibacterial properties. Furthermore, our GC-MS analysis identified the presence of phenolic, Fatty acids, and terpenoids compounds in the root extract of H. indicus, which hold potential therapeutic applications.

Background: Corchorus olitorius L. (Family: Tiliaceae) or {\textquoteleft}Tossa Jute or Nalta Jute is an important fiber crop in India and Bangladesh. Its leaves are used as folk medicine, food source and have demulcent, diuretic, lactagogue, purgative, antidiabetic, anticancer, antioxidant, anti-inflammatory and tonic effects. The aim of the research is to evaluate the pharmacognostic characteristics and antimicrobial activity of Corchorus olitorius L. (C. olitorius). Materials and Methods: The pharmacognostic studies were carried out in terms of organoleptic, macroscopic, microscopic, physico-chemical evaluation, phytochemical screening, fluorescence analysis, TLC fingerprinting by standard procedures. Antibacterial activity against gram-negative bacteria E. coli was determined by agar well diffusion method. Results: The leaf of C. olitorius showed serrate margin, stipules at the base, and acute to acuminate apex. Leaves surface microscopy showed numerous prismatic calcium oxalate crystals and covering trichomes. The moisture content 6.6\% w/w, ethanol and water-soluble extractive value 4 and 17.6\% w/w, total ash 12\% w/w, while acid insoluble and water-soluble ash value 2.2 and 2.0\% w/w respectively were determined. Phytochemical screening showed the presence of flavonoids, polyphenols, phytosterols/triterpenoids, alkaloids, carbohydrates, tannins, and proteins. Thin layer chromatographic profiling of ethanolic extract was carried out which showed different Rf values. The antimicrobial test showed that aqueous extract has better antimicrobial activity around the tested bacteria (E. coli) than ethanolic extract. Conclusion: The results are helpful in the standardization of the leaf part of the plant C. olitorius. The aqueous leaf extract possessed antimicrobial properties. There is a need to isolate its constituents responsible for antimicrobial activity.

Background: Justicia gendarussa Burm f. of family Acanthaceae is medicinally important herb used in the treatment of inflammatory disorders, asthma, hepatic injuries, pathogenic infection and also shows antiproliferative activity against various cancer cell lines. Materials and Methods: Pharmacognostical evaluation (macro-microscopy, physicochemical analysis and preliminary phytochemical analysis), high-performance thin layer chromatography (HPTLC) fingerprinting and chemical profiling by gas chromatography-mass spectrometry (GCMS) of dried roots of J. gendarussa were done according to quality standard procedures. Results: Microscopic analysis revealed the compact arrangement of cells in cork region and thin-walled cortex beneath epidermis. Parenchymatous cells with xylem vessel were observed in the roots of J. gendarussa. Physicochemical studies revealed loss on drying (10.474\%), total ash (2.990\%), acid-insoluble ash (0.099\%), water-soluble ash (1.528\%), alcohol-soluble extractive value (0.564\%) and water-soluble extractive value (4.11\%) of the raw drug. Preliminary phytochemical analysis of ethanolic extract of J. gendarussa showed the presence of alkaloid, steroid, flavonoid, phenol, carbohydrate, saponin and quinone. Rf, color of the spots and densitometric scan were recorded by HPTLC fingerprinting using toluene: ethyl acetate: formic acid (5.0:4.0:1.0). On photodocumentation, six spots were visualized under 254 nm, nine spots under 360 nm and six spots at 620 nm. Identification of components in ethanolic extract of J. gendarussa was done by GC-MS. GC-MS results in the presence of oleic acid, 9,12-octadecadienoic acid, 6,9,12-octadecatrienoic acid and estra-1, 3,5 (10)-trein-17-β-ol in ethanolic extract of J. gendarussa. Conclusion: These specific identities will be useful in identification and authentication of the raw drug in dried form.
