Evaluation of antibacterial and antifungal activity of root and root callus extracts of Trianthema decandra L.

In this study, the antibacterial activity of various organic solvent extracts of Ocimum sanctum L leaves, flowers and shoots was determined in vitro using agar diffusion method and MIC tested against the isolated soil bacteria. The identified bacteria were Paenibacillussp. L32, Paenibacillussp. BF38, Bacillus megaterium, Terribacillussp. 3LF, Bacillus simplex and Bacillus cereus. Various organic extracts of Ocimum sanctum L revealed a good antibacterial activity against about all bacteria. Results showed that the best extract was methanol because highest inhibition zone were obtained by this extract and all studied bacteria were inhibited. At a concentration of 500 µg/disc, the highest microbial inhibition was found 19.2±.76 mm against Bacillus simplex for methanol extract, 15.7±0.58 mm on Terribacillus sp. 3LF for ethanol extract of flower, 14.0±2.0 mm on Terribacillus sp. 3LF for ethanol extract of leaves, 13.34±0.58 mm on Bacillus megaterium for n-hexane extract and 11.7±0.6 mm on Terribacillus sp. 3LF for chloroform extract, respectively and MIC (64, 128, 256 and 512 µg/ml, respectively). Most of the cases, antibacterial activity with commercial antibiotics such as amoxicillin and erythromycin, organic extracts exhibited similar or higher antibacterial activity than standard drug. The results of this study suggest that the organic extracts of Ocimum sanctum L leaves can be a source of natural antimicrobial agents with potential applications.

Zaleya pentandra, a plant species found in disturbed soils and roads across Asia, Africa, and Australia, has been traditionally used for treating various ailments such as coughs, malaria, kidney stones, ulcers, and jaundice. Objectives: To conduct a quantitative examination of Z. pentandra, focusing on proximate analysis and metabolite composition and to better understand its features. Methods: Crude plant powder underwent analysis for total moisture, total ash, water-soluble ash, acid-insoluble ash, sulfated ash, water-soluble extractive, and alcohol-soluble extractive. Quantification (mg/gm) of principal metabolites i.e., carbohydrates, proteins, and lipids in the crude plant powder was done. Dry plant powder was subjected to counter-current extraction using n-hexane, petroleum ether, and chloroform. UV-visible and FTIR spectra were examined to determine the chemical composition. Results: Our findings showed total moisture (9.306%), total ash (21.73%), water-soluble ash (12.75%), acid-insoluble ash (0.35%), sulfated ash (29.75%), water-soluble extractive (6.23%), alcohol-soluble extractive (5.7%). Principal metabolites included high quantities of carbs (65.34), proteins (15.29), and lipids (30.90) in the crude plant powder. n-hexane (3.073%), petroleum ether (4.45%) and chloroform (7.47%) were extracted. UV-visible and FTIR spectra revealed a variety of chemicals, indicating both polar and non-polar molecules with possible oxidative characteristics. Conclusions: Z. pentandra exhibits high carbohydrate, protein, and fat content. The diverse chemical composition suggests a high oxidative potential, supporting its traditional therapeutic uses. Further research, especially in identifying and isolating bioactive components, is warranted. Z. pentandra holds promise for traditional medicine and broader applications based on its nutritional and bioactive potential.
