Abstract
The South African medicinal plant Oncosiphon suffruticosum (L.) Källersjö is an important
remedy used to treat chronic, respiratory, and skin ailments. From the essential oil (EO) extracted by
the hydrodistillation, sixteen constituent components were identified with oxygenated monoterpenes:
camphor (31.21%), filifolone (13.98%), chrysanthenone (8.72%), 1,8-cineole (7.85%), and terpinen-4-ol
(7.39%) as predominant constituents. In the antibacterial activity study, the EO was found most
susceptible against Pseudomonas aeruginosa with an MIC of 6.4 mg/mL; however, it showed the same
activity against Staphylococcus aureus and Escherichia coli with an MIC value of 12.8 mg/mL. The
sun protecting factor (SPF) of the EO was found to be 2.299 and thus establishing it as a potentially
important cosmeceutical for sunscreen applications. This is the first report investigating the essential
oil of O. suffruticosum for its chemical composition and skin-related in vitro biological activities viz
antibacterial, antioxidant capacity, antityrosinase, and sun protection factor.
