Abstract
Background: Herbal products, typically derived from plant sources, are often perceived as safer
alternatives and are widely used for their therapeutic and antioxidant benefits. This study will help to determine physicochemical and antioxidant properties of some selected liquid herbal products. Methods: Seven selected liquid herbal products (Mojeaga herbal remedy, Goodwill's herbal mixture, pro-life herbal remedy malaria & Typhoid, Goko cleanser, Ganacin G-7 ulcer solution, Evaking herbs ulcer & pile removal and orijin bitter) were obtained from various pharmacies throughout Edo State, Nigeria. Samples underwent sensory evaluation, followed by measurements of specific gravity, pH, viscosity, and antioxidant properties through DPPH radical scavenging activity using spectrophotometric analysis at 517 nm wavelength. Results: The organoleptic properties evaluation of the products revealed that most of the samples had a very strong characteristics odor, except Mojeaga and Goodswill that have aromatic scent, they
all taste bitter except Ganacin and Evakings herbs that were sweet and tasteless. In terms of color, majority of the products showed deep brown coloration, while Ganacin and goko cleanser appeared moudy and dark. The specific gravity ranges from (0.72 to 1.83 g/mL). The pH analysis showed that all products were acidic (ranging from 3.10 to 6.96). All seven herbal products exhibited high viscosity which ranges from (2805 to 5748 cp). The antioxidant assay indicated that all the products contain antioxidant which ranges from (39.13% to 65.22%). Conclusion: The findings suggest that most of the evaluated herbal products possess notable
antioxidant properties and favorable physicochemical characteristics. These attributes act
synergistically to enhance product stability and reduce the risk of degradation or contamination
during storage. Moreover, the antioxidant potential of these formulations may contribute to
protection against infections and minimize adverse effects when used by patients.
