Even though the mode of action on the S. guianensis vital oil was not addressed in detail right here, and as 9-Hydroxyrisperidone palmitate In Vitro previously described for the C636 mosquito cell lines24, our in vitro bioassays with this vital oil induced necrotic and apoptotic cell death on lepidopteran cultured cells. These effects might be derived from the actions of terpenes (e.g., the monoterpene -myrcene) present in the critical oil. Terpenes generally allow the crucial oil to diffuse by means of the cell membrane, causing not merely cell membrane alterations but additionally uncoupling oxidative phosphorylation a.
