Endophytes are a rich source of novel bioactive compounds that can be used for various applications, such as drug discovery and agricultural biotechnology . Metabolomics has been increasingly used to discover and characterize these compounds . For example, a study by used LC-MS to investigate the metabolic profile of the endophytic fungus Penicillium citrinum isolated from the medicinal plant Ocimum sanctum . The authors identified several novel compounds, including citrinadin A and citrinin H1, that exhibited antimicrobial and anticancer activities. Similarly, a study by used GC-MS and LC-MS to investigate the metabolic profile of the endophytic fungus Chaetomium globosum isolated from the medicinal plant Ginkgo biloba . The authors identified several bioactive compounds, such as chaetomugilin D and chaetoglobosin A, that exhibited antifungal and cytotoxic activities.
