Abstract

The Plectranthus genus belongs to the Lamiaceae family and consists of around 300 species distributed from Africa to Asia and Australia. Several studies have reported that Plectranthus species are rich in abietane-type diterpenes, such as royleanones, which are interesting in the treatment of various diseases. One of such species is Plectranthus hadiensis (Forssk.) Schweinf. ex Sprenger, which has been documented to be useful in several types of cancer (1). The objective of this work is to present the preliminary results of extraction, fractionation, isolation and bioactivity of the aerial parts of this plant. These data indicate a great difference between the acetonic extracts from leaves and those from stems, mainly in their content of 7a-acetoxy-6b-hydroxyroyleanone, which has cytotoxic properties (2,3). Currently, phytochemical studies are ongoing to elucidate the main abietanes responsible for the biological activity.
