“…Enzymatic antioxidants may not be enough to sustain optimal cellular activities in the presence of oxidative stress, and non-enzymatic (dietary) antioxidants may be necessary (Dias et al, 2020). Antioxidants either in the form of raw extracts or their chemical constituents are particularly powerful at stopping the damaging processes brought on by oxidative stress (Shah, 2015).…”

Background and Purpose: Medicinal plants are used for the treatment of diseases because of the presence of therapeutic phytochemical constituents. Antioxidants play important roles in preventing and mitigating diseases. The plant Cola rostrata K. Schum (Sterculiaceae) is used in traditional medicine for pain relief, diabetes, erectile dysfunction, dental hygiene, and other conditions. The objective was to evaluate the total phenolic content and in vitro antioxidant properties of C. rostrata leaf extract and fractions. Methods: The dried and pulverized leaves of the plant were soaked in methanol for 72 h for extraction. Fractionation of the methanol extract was done using n-hexane, ethyl acetate, and methanol in a column. The extract and fractions were screened for phytochemical constituents. The total phenolic content was determined using the Folin-Ciocalteu assay. In vitro antioxidant properties were evaluated using the 2,2-diphenyl-1-picyhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and hydroxyl radical scavenging assay against ascorbic acid (standard). Results: The phytochemical screening revealed the presence of alkaloids and flavonoids among others. The total phenolic content was higher in the extract (1.34 mg/g GAE) compared to the fractions. In the DPPH assay, the n-hexane fraction had lower IC50 (0.93 µg/mL) than the standard (3.44 µg/mL). In the FRAP assay, the ethyl acetate fraction had EC50 of 0.71 µg/mL which was lower than that of the standard (1.34 µg/mL). In the hydroxyl radical scavenging assay, the n-hexane had lower IC50 (0.37 µg/mL) than the standard (1.45µg/mL). Conclusion: The findings suggest that the leaves of C. rostrata have potential antioxidant properties which may be due to the high phenolic content.

Background: Medicinal plants have been used in traditional medical practices since prehistoric times. It is popularly known that roots, rhizomes, and leaves of some Smilax species are widely used for treating various diseases such as toothache, muscular pain, urinary diseases, and jaundice. Methodology: This review aims to document the information regarding major phytochemicals and pharmacological activity of selected Smilax species in India. Details of different species of Smilax species in India were collected from online databases such as https://wcsp.science.kew.org/(2022), https://powo.science.kew.org (2022), and https://www.ipni.org (2022). All the available information related to phytochemistry and pharmacological activities was collected from electronic databases such as Academic Journals, Springer, PubMed, Google Scholar, ScienceDirect, MEDLINE, Scopus, Web of Science, and other primary and secondary sources. Results: Literature survey revealed that members of the genus Smilax possess large quantities of steroids and phenolic compounds and possess various bioactive properties such as antibacterial, antifungal, antioxidant, and analgesic activities. Conclusion: This review concludes that more research on the genus Smilax is required to identify and evaluate the presence of potential bioactive constituents, and further investigations may be led to the development of new drugs.
