Endophytic fungi are microorganisms that live in plants, without negative effects and are mutually related to hosting plants. Exploration of bioactive compounds from Endophytic fungi is easier and cheaper because they do not require a large area, a short growing time, and uncomplicated mixed compounds. Endophytic fungi are new and patent base secon...

Indonesia is rich in diversity of medicinal plants, vital in traditional medicine and the pharmaceutical industry. However, overharvesting, along with population growth, land use changes, deforestation, and climate change, endanger these plants. This review investigates the potential of endophytic endosymbiont as an alternative. These endosymbionts can synthesise bioactive compounds similar to those found in medicinal plants. This study compiled data from various sources on endophytic fungi and their bioactivity. The review aims to categorise Indonesian medicinal plants, to identify their associated endophytic fungi from different plant parts, and to assess their bioactivity. The results revealed numerous medicinal plant families and a variety of endophytic fungi isolated from fruits, leaves, twigs, bark, roots, and rhizomes. These fungi exhibited bioactivities, including antioxidant, anticancer, antidiabetic, and antimicrobial effects, with metabolites such as alkaloids, flavonoids, peptides, phenols, polyketides, quinones, steroids, and terpenoids. Fusarium and Colletotrichum were the most common endophytic fungi found. Notably, the biological activity was consistent among endophytic fungi from various host organs, but variations were observed according to the host's geographical origin. This suggests that Indonesia's diverse geography influences metabolite production and activity. However, the same host plant may harbour different species in distinct organs. These findings indicate that endophytic fungi within medicinal plants represent a promising source of bioactive compounds for future Indonesian medicine production. Future research should explore metabolite compounds and bioactivity across different geographical regions.
... Results of the isolation of pendophytic fungi from the S. malaccense twig obtained five isolates, YR1-YR5, found four ( Figure 1. The four genera of endophytic fungi found as a result of isolation and identification on S. malaccense twigs (Table 1) are often found on the rhizomes and roots of other medicinal plants, especially the Fusarium genus (Jigjiddorj et al., 2024), but are also found in S. aqueum, S. zeylanicum, S. jambos (Aini et al., 2023;Habisukan et al., 2021;Syarifah et al., 2021), these findings indicate that there are certain types of endophytic plant fungi that can struggle in different anatomical structures and conditions of host plant (Alam et al., 2021). ...
Searching for medicinal raw materials derived from the isolation of secondary metabolite compounds is still being carried out to cure a range of illnesses, including infections and degenerative diseases caused by bacteria and free radicals. This research used endophytic fungi extract from the twig of Syzygium malaccense. The diffusion method was used for antibacterial activity and 2,2-diphenyl-1-picrylhydrazyl (DPPH) was used for antioxidant activity. Chemical compound was identified by using NMR spectroscopic method. This research found 5 isolate of endophytic fungi from twig of S. malaccense (YR1 – YR5). Strong antibacterial and antioxidant activity were showed by YR5. Based on molecular identification, YR5 was Fusarium verticillioides. Pure compound prodeced by endophytic fungi F. verticilloides was naphthalene (3-methoxy-7 methylnaphthalene-1,6-diol). This finding can be used as a basis for drug development.

Medicinal plants are a promising host for endophytic fungi to produce secondary metabolites relevant for food and health. In this study, we evaluate antioxidant activity to determine the species of endophytic fungi isolated from Syzygium aqueum. Endophytic fungi were isolated from leaf stalks through surface sterilization. The fungi’s isolate was identified with morphology and molecular analysis (ITS-rDNA). The pure fungi strain was cultivated on PDB media for 4 weeks, and metabolites were extracted using ethyl acetate. The crude extract of endophytic fungi was examined for its antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH). The pure compound was isolated using the chromatography method, and its structure was determined using spectroscopy analysis involving NMR 1D and 2D. In total, four obtained endophytic fungi were isolated from leaf stalks. The fungi with good antioxidant activity (IC50 59.2 µg/mL) were identified as Beltrania rhombica. The characteristics of the pure compound are white-yellowish powder with IC50 44.2 µg/mL. Based on spectroscopy analysis, the pure compound was identified as 3-(hydroxyl(3,4,5-trihydroxylphenyl)methyl)-3,4-dihydro-2H-pyran-4,5,6-triol.

Natural bioactive substances have been discovered produced of intracellular fungi. Intracellular fungi, as well as endophytic fungi, it can be found in organs are leaves, stems, roots, fruits, flowers, and seeds. This study aimed to specify for antioxidant activity of intracellular fungi Jambu Bol (Syzygium malaccense) mediated and identify secondary metabolites compounds. The liquid culture was partitioned with ethyl acetate solvent. Using chromatographic techniques, extracts were separated from their secondary metabolites with antioxidant activity apply the DPPH procedure. Its chemical structure was determined using NMR spectroscopic research, and endophytic fungi were recognized using phenotypic characteristics and molecular classification. The endophytic fungus isolation yielded four isolates: YF11, YF12, YF13, and YF14. YF12, with an IC50 of 53.03 g/mL, was the fungus that exhibited good antioxidant activity. Pure chemical secondary metabolites compounds were identified as 2-(4-hydroxyphenyl)-4-methoxytetrahydrofuran-3-ol. Tritirachium oryzae was identified as the endophytic fungus YF12 based on morphological studies and a phylogenetic tree. To boost its antioxidant activity, more study is needed to perform a semi-synthetic reaction on this pure molecule.
