In this research a multidisciplinary approach was used to unveil the genetic, metabolic uniqueness and relationships of endemic Mascarene Aloes (Aloe macra, Aloe purpurea, Aloe tormentorii) with respect to Aloe vera. Nuclear magnetic resonance spectroscopy, DNA sequencing and antioxidant profiles of these Aloes were studied. Principal component analysis following 1H NMR revealed the specificity of the Mascarene Aloes relative to Aloe vera. The superior free radical scavenging ability of A. purpurea, A. macra and A. tormentorii as compared to other Aloes was also unveiled. Phylogenetic analyses of chloroplast genes and ITS region sequences of these Mascarene Aloes were done using maximum parsimony and Bayesian analysis. Mascarene Aloes clustered within one clade separate from Aloe vera confirming their relative recent emergence in this genus. Results from this study showed that there is sufficient evidence at the metabolomic and molecular level to distinguish between Aloe ​purpurea from Mauritius and that of Reunion. © 2016 SAAB [less ▲]

Introduction - Aloe tormentorii, A. purpurea and A. macra are used as multipurpose folk medicines in Reunion and Mauritius Islands and are mistaken for the introduced Aloe vera.Objective - To compare the phytochemical, antimicrobial and DNA profiles of Aloe endemic to Mauritius and Reunion with the profiles of A. vera.Methodology - Leaf extracts of these Aloe species were analysed using standard phytochemical screening techniques, TLC and by HPLC. These extracts were also assayed for antimicrobial activity using microdilution techniques. Genetic diversity was studied using RAPD markers.Results - Phytochemical and antimicrobial assays and RAPD analysis showed that Mascarene Aloe species were very different from A. vera.Conclusion - This study is the first report highlighting the differences between Aloe sp.p from Mascarene and Aloe vera at the metabolic and genomic level.
