Analysis of the Bioactive Content of Kirinyu (Chromolaena Odorata) Extract through GC-MS Phytochemical Testing to Improve Laboratory Skills of Biology Students at Jabal Ghafur University

Kirinyu (Chromolaena odorata) is a plant that the people of Aceh believe can cure several diseases.The results of the research that has been carried out show that the content of kirinyu extract has the potential to be antihypercholesterolemic, antibacterial, and accelerate wound healing.This research aims to determine the content of bioactive compounds contained in kirinyu leaves.The method used is the extraction of dried kirinyu leaf powder in 96% ethanol solvent, then dissolved in several reagents for phytochemical screening (alkaloids, tannins, flavonoids, steroids, terpenoids, and saponins) and analyzed using gas chromatography-mass spectrometry (GC-MS) to get polar content information.The results of the phytochemical screening showed it was positive for containing tannins, flavonoids, saponins, and alkaloids.GC-MS analysis of kirinyu leaf extract showed that there were 39 compound components extracted.The research results also showed that there were four polar bioactive compounds at the highest peak, namely 9,12-Octadecadienoic acid (Z, Z)-, delta.-Cadinene,trans (.beta).-caryophyllene and gamma.-Muurolene,obtain related laboratory skills Phytochemical screening and gas chromatography-mass spectrometry (GC-MS) analysis as authentic experiences to promote science to students.
