Introduction

Indonesia’s archipelago hosts exceptional biodiversity and a long-standing tradition of plant-based medicine. Jamu remains widely used, while policies and industry efforts increasingly aim to strengthen evidence-based herbal medicine development and move selected products toward standardized herbal medicines and phytopharmaceuticals (Elfahmi et al., 2014) [4]. This context creates a strong rationale for universities to become centers of excellence in medicinal plant biochemistry: discovery, validation, and translational pathways can be anchored in local species and local health priorities.

Medicinal plant biochemistry spans multiple levels of analysis. At the molecular level, it studies secondary metabolites, bioactive peptides, polysaccharides, and enzyme systems that underpin therapeutic effects. At the analytical level, it uses chromatography–mass spectrometry and NMR to profile complex extracts. At the translational level, it requires quality control, marker selection, contamination screening, stability testing, and increasingly, clinical evidence pathways. These demands make medicinal plant biochemistry a multidisciplinary domain bridging biology, chemistry, pharmacy, data science, and public health. Yet success is not guaranteed. Many promising medicinal plant studies fail to translate because they lack reproducible sampling design, have uncertain compound identification, rely on weak bioassay validation, or overlook governance and ethics. Access-and-benefit sharing (ABS) governance under the Nagoya Protocol framework requires prior informed consent and mutually agreed terms when accessing genetic resources and associated traditional knowledge (Convention on Biological Diversity, 2011) [3]. Governance complexity can slow research but also provides an opportunity to build trusted partnerships and legitimate long-term programs (Oberthür & Rosendal, 2014) [9].

Additionally, variability is intrinsic: the same species may present different chemotypes across geography, season, and cultivation history. Without careful metadata and vouchers, results are difficult to reproduce or compare across studies. Meanwhile, metabolomics and natural products science face an annotation bottleneck: many detected features cannot be confidently identified without standards or high-quality spectral libraries (Wolfender et al., 2019) [16]. This article synthesizes literature up to 2024 to answer three questions: (1) What are the main scientific and institutional challenges of medicinal plant biochemistry research in Indonesia? (2) What opportunities and value pathways exist for higher education? (3) What practical roadmap can universities follow to improve research quality, reproducibility, and translation while ensuring ethical and sustainable practice?

2. Literature Review

2.1. Indonesian herbal medicine context and the evidence

ladder A distinctive feature of Indonesia is the coexistence of widespread traditional use and expanding evidence expectations. The concept of jamu-to-phytopharmaceutical development reflects an “evidence ladder,” in which traditional formulations can evolve through standardization and preclinical/clinical evidence toward regulated phytopharmaceuticals (Elfahmi et al., 2014) [4]. This ladder requires biochemistry research to provide chemical markers, bioactivity mechanisms, and quality assurance evidence that can support regulatory and clinical evaluation.

2.2. Plant metabolomics standards and implications for

medicinal plant research Plant metabolomics enables comprehensive profiling of plant extracts and supports chemotype comparisons, biomarker selection, and pathway inference. Foundational framing emphasized metabolomics as a bridge between genotype and phenotype (Fiehn, 2002) [6]. Minimum reporting standards were proposed to improve comparability and reproducibility (Sumner et al., 2007) [11], while later reviews emphasized plant-specific challenges such as genotype × environment effects and pathway interpretation (Fernie & Tohge, 2017) [5]. For medicinal plants, these standards translate into concrete requirements: QC samples, internal standards, batch randomization, detailed metadata, and transparent identification confidence.

2.3. Natural products dereplication, molecular

networking, and annotation bottlenecks A recurring limitation in medicinal plant research is rediscovery and weak compound identification. Strategies such as dereplication—identifying known compounds early—are essential for efficiency. Reviews highlight innovative approaches combining LC–MS/MS, NMR, and computational annotation to accelerate dereplication and structure elucidation (Wolfender et al., 2019) [16]. MS/MS-based molecular networking has been promoted as an efficient approach to dereplication and comparative analysis in complex mixtures, with continuing methodological refinements and applications (Qin et al., 2023) [10]. However, annotation remains limited by incomplete databases and by the scarcity of authentic standards for many locally important compounds.

2.4. Ethnopharmacology ethics, traditional knowledge, and community partnerships Ethnopharmacology provides valuable hypotheses by linking community practices and local disease priorities to plant selection, but it also requires ethical safeguards. Best-practice recommendations emphasize respectful engagement, transparency, and methodological rigor to avoid extractive research and to protect community rights (Heinrich et al., 2020) [7]. When traditional knowledge is involved, ABS governance under the Nagoya Protocol framework becomes central, requiring prior informed consent and mutually agreed terms for access and benefit-sharing (Convention on Biological Diversity, 2011) [3].

2.5. Governance and quality: ABS, regulation, and

quality control Governance affects both timelines and legitimacy. Scholarly analysis of ABS governance highlights variation in national implementation and the practical complexity of compliance, especially for collaborative research and international partnerships (Oberthür & Rosendal, 2014) [9]. In addition to governance, quality control is a scientific and public-health necessity. WHO guidance provides frameworks for quality control and contamination/residue considerations in herbal medicines (World Health Organization, 2011) [14]. Indonesian regulatory framing for traditional medicines—including categories such as jamu, standardized herbal medicines, and phytopharmaceuticals—further reinforces the need for standardized markers, quality systems, and evidence-based pathways (Badan Pengawas Obat dan Makanan Republik Indonesia, 2019) [2].

3. Method

This article uses a framework synthesis approach. We integrated peer-reviewed articles and authoritative guidance (≤2024) to construct an evidence-informed account of challenges and opportunities in Indonesian medicinal plant biochemistry research in higher education. We organized sources into six clusters: (1) Indonesia herbal medicine development; (2) plant metabolomics methods and reporting standards; (3) dereplication and molecular networking; (4) ethnopharmacology ethics and traditional knowledge; (5) ABS governance and policy; and (6) quality control and standardization guidance for herbal medicines. The synthesis is reported as design-oriented results: Figure 1 presents an end-to-end pipeline from ethnobotanical prioritization to sustainable translation, and Figure 2 maps key constraints and leverage points. Tables summarize methodological options, mitigation strategies, and institutional action pathways. References are restricted to publications no later than 2024 to support a backdated 2024 publication.

4. Results and Discussion

Fig 1: Pipeline for medicinal plant biochemistry research in Indonesia Fig 2: Challenges and opportunities matrix in Indonesian medicinal plant biochemistry research Results are presented as a structured synthesis of constraints and leverage points. Figure 1 shows an end-to-end pipeline for medicinal plant biochemistry research in Indonesia, emphasizing governance (ABS), taxonomy and chemotype documentation, analytical profiling, and the evidence ladder toward phytopharmaceuticals. Figure 2 summarizes how challenges and opportunities cluster along two dimensions: governance/biological variability and analytical/translational capacity.

4.1. Scientific challenges: variability, identification, and

reproducibility The dominant scientific constraint is variability: metabolite profiles shift with organ, season, habitat, and post-harvest processing. This is particularly acute for medicinal plants collected from wild or semi-wild sources. Plant metabolomics standards imply that sampling design and QC practices are not optional; they are prerequisites for credible conclusions (Fiehn, 2002) [6]; (Sumner et al., 2007) [11]. A second scientific bottleneck is compound identification. While LC–MS/MS detects thousands of features, only a fraction can be confidently annotated without standards or curated libraries. Dereplication strategies and molecular networking reduce rediscovery and improve comparative analysis, but confidence levels must be reported transparently (Wolfender et al., 2019) [16]; (Qin et al., 2023) [10]. 4.2. Governance challenges: ABS, traditional knowledge, and long timelines ABS compliance and traditional knowledge governance affect whether research is ethical, publishable, and translatable. In practice, unclear permit pathways can delay field sampling and constrain collaborations. However, governance also creates an opportunity: universities that institutionalize ABS workflows and benefit-sharing templates can become trusted partners, enabling long-term programs rather than one-off extractive projects (Convention on Biological Diversity, 2011) [3]; (Oberthür & Rosendal, 2014) [9]; (Heinrich et al., 2020) [7].

4.3. Quality, safety, and the evidence ladder

Translational herbal medicine requires quality and safety assurance. WHO guidance emphasizes contaminants and residues and broader quality control methods (World Health Organization, 2011) [14]. Indonesian regulation distinguishes traditional medicine categories and strengthens requirements for safety, quality, and evidence as products move up the evidence ladder (Badan Pengawas Obat dan Makanan Republik Indonesia, 2019) [2]. Biochemistry research supports this ladder by identifying marker compounds, developing fingerprints, validating stability, and linking chemistry to bioactivity mechanisms.

4.4. Opportunity pathways for Indonesian universities

Indonesian universities can build globally visible niches by focusing on under-studied endemic species, developing local spectral libraries and metabolomic reference datasets, and integrating ethnobotanical knowledge with rigorous biochemical workflows. Universities can also strengthen translation through partnerships with hospitals, SMEs, and government programs, with a particular focus on standardized extracts, diagnostics, and sustainable agriculture inputs. Finally, sustainability must be built in: cultivation and conservation plans reduce overharvesting risks, and green extraction approaches reduce solvent and energy footprints.

4.5. A practical institutional roadmap

The synthesis implies that universities should invest in: (1) governance readiness (ABS and ethics support), (2) taxonomy and voucher systems, (3) shared analytical infrastructure (LC–MS/MS, NMR, bioinformatics), (4) reproducible workflows and reporting checklists, (5) curated local databases and spectral libraries, and (6) translation platforms that include QA/QC, safety testing, and partner engagement. These institutional investments convert dispersed projects into a coherent research program with credible outputs and scalable societal value.

5. Conclusion

Medicinal plant biochemistry research in Indonesia offers extraordinary opportunities because it is grounded in biodiversity and living traditions of herbal medicine. Yet the field faces persistent challenges—ABS governance, ethical engagement with traditional knowledge, taxonomy and voucher rigor, chemotype variability, annotation bottlenecks, limited analytical capacity, and difficulties in standardization and clinical evidence pathways.

This article provides a practical synthesis toolkit: two conceptual figures (pipeline and challenge–opportunity matrix) and three implementation tables. The core recommendation is to treat governance readiness, reproducibility, and data stewardship as primary scientific outputs, on par with publications. With shared analytical infrastructure, curated local libraries, and responsible partnerships, Indonesian universities can strengthen the credibility and translation of medicinal plant biochemistry while protecting biodiversity and community rights.
