Tabebuia species in South America have many functions as traditional medicines, while Tabebuia species in Indonesia are useful for making the air clean and becoming ornamental plants. The aim of this study was to determine the content of bioactive compounds and antimicrobial activity of methanol extracts of leaves and flowers of various Tabebuia genus. The method to determine the content of bioactive compounds using GC-MS (Gas Chromatography-Mass Spectrometry) method while to determine antimicrobial activity using Kirby-Bauer method. Bioactive compounds found in all extracts were Siliconfett and Cyclotrisiloxane, hexamethyl. Methanol extract of T. aurea leaves at a concentration 6.25% had the highest mean ZOI against C. albicans. The methanol extract of T. rosea leaves at 100% concentration had the highest mean ZOI against E. coli. The methanol extract of T. aurea leaves at a concentration 25% has the highest mean ZOI against S. aureus.

“…Compounds were identified by comparison of mass fragmentation using NIST digital library spectra 2.0 (2008) and the fragmentation pattern. n-Alkanes were characterized based on comparison of retention times with components of a homologous series in the range C 19 -C 40(Carvalho et al 2021). Hydrocarbon patterns (C 19 -C 40 ) were also analyzed via GC-MS.…”

hydrocarbons. These primarily minimize water loss, but are also known to have numerous functions in arthropod interactions with other animals. Typically, they are contact chemicals that participate in specific and sexual recognition, in addition to providing a wealth of information about the individual. In harvesters, there is ample evidence for the importance of contact chemoreception from both the sender and receiver perspectives. However, we had no idea which chemicals would be relevant in these interactions. We therefore described the cuticular hydrocarbons of both sexes in one species of harvester, having detected numerous chemicals used in chemical communication in other taxa, as well as a difference between males and females. The thesis is divided into 4 independent chapters, but under the umbrella of cuticular structure in Opiliones. Each consists of one publication. The first is published, the second is accepted, the third and fourth are submitted.
