What is Natural Products and Applications?
Natural Products and Applications is a research field in agricultural and biological sciences that investigates the extraction, biosynthesis, and practical uses of plant secondary metabolites, herbal medicines, and biomass-derived materials such as activated carbon for applications in phytomedicine, antioxidants, and wastewater treatment.
This field encompasses 25,979 papers focused on agricultural research topics including plant secondary metabolites, sorghum, millets, oxidative stress, antioxidants, egg yolk color, phytomedicine, space science, and activated carbon production. Key studies address extraction of phenolic and flavonoid compounds from plants like Etlingera elatior, as shown in 'Penetapan Kadar Fenolik dan Flavonoid Total Ekstrak Metanol Buah dan Daun Patikala (Etlingera elatior (Jack) R.M.SM)' (2015) with 288 citations. Applications extend to biosorbents from agricultural wastes and herbal pharmacopeias documented in works like 'Farmakope Herbal Indonesia' (2017, 304 citations).
Topic Hierarchy
Research Sub-Topics
Plant Secondary Metabolites Extraction
This sub-topic covers methods like solvent extraction, supercritical CO2, and ultrasound-assisted techniques for isolating flavonoids, phenolics, and terpenoids from medicinal plants. Researchers optimize yields, characterize compounds via HPLC-MS, and evaluate bioactivity.
Activated Carbon from Agricultural Waste
This sub-topic focuses on producing high-surface-area activated carbon from peels, shells, and husks via chemical and physical activation for water purification. Researchers study adsorption isotherms, porosity via BET analysis, and heavy metal removal efficiency.
Phytomedicine and Antioxidant Properties
This sub-topic investigates herbal extracts' DPPH scavenging, FRAP assays, and protective effects against oxidative stress-related diseases. Researchers screen Indonesian plants like Etlingera elatior for total phenolic/flavonoid content and cytotoxicity.
Biosynthesis of Metal Nanoparticles

Sorghum and Millets in Agriculture
This sub-topic covers agronomic practices, drought tolerance breeding, and nutritional profiling of sorghum and millets in Ethiopian farming systems. Researchers assess yield stability, biofortification, and climate resilience.
Why It Matters
Natural products from agricultural sources provide biosorbents for wastewater treatment, with 'High surface area activated carbon prepared from cassava peel by chemical activation' by Sudaryanto et al. (2005) demonstrating high surface area carbon from cassava peel achieving 444 citations for its chemical activation method. Coconut-based biosorbents reviewed by Bhatnagar et al. (2010) in 'Coconut-based biosorbents for water treatment — A review of the recent literature' (220 citations) highlight removal of pollutants like heavy metals and dyes from water. Phytomedicine applications include total phenolic and flavonoid content in Etlingera elatior extracts measured by Ahmad et al. (2015) in 'Penetapan Kadar Fenolik dan Flavonoid Total Ekstrak Metanol Buah dan Daun Patikala (Etlingera elatior (Jack) R.M.SM)' (288 citations), supporting traditional uses for disease treatment, while date palm adsorbents reviewed by Ahmad et al. (2011) (251 citations) aid environmental remediation in industries.
Reading Guide
Where to Start
'High surface area activated carbon prepared from cassava peel by chemical activation' by Sudaryanto et al. (2005), as it provides a clear, highly cited (444 citations) example of transforming agricultural waste into a practical material with detailed methodology accessible to newcomers.
Key Papers Explained
Sudaryanto et al. (2005) in 'High surface area activated carbon prepared from cassava peel by chemical activation' (444 citations) establishes chemical activation from cassava peel, which connects to Ahmad et al. (2011) 'The use of date palm as a potential adsorbent for wastewater treatment: a review' (251 citations) reviewing similar biomass adsorbents and Bhatnagar et al. (2010) 'Coconut-based biosorbents for water treatment — A review of the recent literature' (220 citations) extending to coconut wastes; meanwhile, Ahmad et al. (2015) 'Penetapan Kadar Fenolik dan Flavonoid Total Ekstrak Metanol Buah dan Daun Patikala (Etlingera elatior (Jack) R.M.SM)' (288 citations) shifts to phytochemistry, building on 'Farmakope Herbal Indonesia' by Kemenkes Ri (2017, 304 citations) for herbal standards.
