The need to develop effective alternative for synthetic indicators is the demand of present-day chemistry. The acid-base indicator properties of Rose (Rosa setigera), Allamanda (Allamanda cathartica), and Hibiscus (Hibiscus rosa-sinensis) flowers were examined. Colour pigments were extracted from the flowers via cold and solvent extraction using soxhlet extractor. The pH value of the extracts with wavelengths of absorption was determined using ultraviolet spectrophotometer. From the results obtained, all the extracts exhibited sharp contrast between their colours in acid and base. Their pH was found to be 5.5 for cold extract of Rose and 5.6 for solvent extraction, 5.24 for cold extract of a Hibiscus and 6.52 for solvent extraction, 5.35 for cold extract of Allamanda, and 5.45 for solvent extraction. The maximum wavelengths of absorption obtained for all the extract fall within the visible region of electromagnetic spectrum. These values are almost similar to that obtained from synthetic indicators. It is on these bases that we concluded that natural indicators could be an excellent replacement for synthetic indicators since they are cheap, readily available, simple to extract, not toxic, user and environmentally friendly.

“…The use of plants as therapeutic agents in medicine predates written human history. Ethnobotany, the study of traditional human uses of plants, can be informative for the discovery of future medicines Elumalai and Chinna (2012), Fabricant and Farnsworth (2001), Lai and Roy (2004), and Gupta et al (2018) indicated these issues in their studies. Treating diseases with herbs is common in non-industrialised countries, where herbs can be purchased more affordably than expensive modern pharmaceuticals (Elumalai and Chinna, 2012).…”

Herbal medicine also called botanical or phyto-medicine refers to using a plant's seeds, berries, roots, leaves, bark, or flowers for medicinal purposes. It is becoming more main stream as improvements in analysis and quality control along with advances in clinical research show the value of herbal medicine in the treating and preventing disease. This study was focused on a traditionally prepared and used a product consist of an oil complex (olive oil, Nigella sativa seed oil, rosemary oil); which were researched antimicrobial effect of the product alone, and each oil by disc diffusion methods. Gram-positive and -negative bacteria and yeasts were employed in the susceptibility tests. The antibiotics of imipenem and vancomycin were exploited as positive controls. While there wasn’t effect on Gram-negative bacteria, strong antimicrobial effects were observed on Gram-positive bacteria and yeasts. Nigella sativa seed oil was the most effective. There wasn’t antagonistic and/or synergetic effect for the oil complex product. Although essential oils may be assigned the same name, they may differ widely as antimicrobial agents due to the extraction method used, which may explain the distinctive antimicrobial results reported in different studies. This was the first study to investigate the antibacterial and antifungal effects of this herbal medicine.
