Abstract

Kalakai (scientific name Stenochlaena palustris) is a type of fern that is often used by the people of Kalimantan as a vegetable. The Kalakai plant which grows a lot in the lowland swamp areas of Central Kalimantan is a type of fern plant. Kalakai contains high levels of minerals, vitamin C, folic acid, and protein when compared to other local vegetables in Palangka Raya, Central Kalimantan. The active compounds that act as antioxidants in kalakai are flavonoids and phenols. Flavonoids and phenols act as free radical scavengers to prevent diseases that attack the body thereby strengthening the body's immunity. Traditionally, kalakai is consumed by the Dayak people. This article is a review article that uses the descriptive literature study method to find scientific information or research that proves coherently the benefits or applications of the kalakai. Kalakai which activity as an antioxidant has health benefits such as being able to increase hemoglobin levels so that it can prevent anemia has cytotoxicity in MCF-7 breast cancer cells and prevents antihyperlipidemic by reducing Low-density lipoprotein (LDL).

Abstract

Metabolomics has emerged as a critical field in understanding biological processes and disease mechanisms, necessitating advancements in analytical techniques to handle complex biological samples. This review explores the global landscape of metabolomics, with a focus on the use of spectroscopy and spectrometry. Techniques such as UV-Vis and Fourier Transform InfraRed (FTIR) spectroscopy offer fast and cost-effective metabolite tracing but are limited by their sensitivity, particularly for low-abundance metabolites. Nuclear Magnetic Resonance (NMR) spectroscopy, despite being less sensitive than mass spectrometry (MS), provides unparalleled structural information, distinguishing metabolites with similar mass-to-charge ratios. NMR's capability to detect metabolites in the 1-10 µM range highlights its effectiveness in metabolomics. This review categorizes advancements in these techniques, starting with global contributions to spectroscopy, followed by detailed discussions on FTIR strategies for metabolite tracing, and concluding with NMR's qualitative and quantitative applications in metabolomics and disease diagnostics. The review underscores the continuous development in sample preparation and data integration, enhancing the accuracy and applicability of these techniques, positioning NMR and FTIR as essential tools in modern metabolomic research.
