Ocimum basilicum and Ocimum americanum: A Systematic Literature Review on Chemical Compositions and Antimicrobial Properties

This systematic review aimed to evaluate the chemical compositions and Pharmacological applications of Ocimum basilicum, known as sweet basil, and Ocimum americanum, known as hoary basil, to assess their antimicrobial properties. Both plants are renowned for their culinary uses and medicinal properties, with studies suggesting potential therapeutic benefits due to their rich essential oil. A systematic approach was adopted to gather and analyze the relevant literature on the chemical profiles and pharmacological activities of Ocimum basilicum and Ocimum americanum. Electronic databases including Web of Science, ScienceDirect, Google Scholar, and PubMed were searched using keywords such as chemical composition of Ocimum basilicum, chemical composition of Ocimum americanum, antimicrobial activities of Ocimum basilicum, and antimicrobial activities of Ocimum americanum. Ninety-nine articles meeting the determined inclusion criteria were incorporated in this systematic review. Several studies have consistently demonstrated the antimicrobial activities of these 2 plants, although the specific compounds responsible for this activity vary between the 2 species. The diverse array of bioactive molecules present in these plants contributes to their pharmacological effects, suggesting avenues for further research into their therapeutic applications. This review supports the continued exploration of the medicinal properties and potential development of sweet basil and hoary basil as antimicrobial agents.
