Plant-derived vitamins are a kind of micronutrient which is not only required for the regulation of cell growth, development and metabolism of plant, but also essential to maintain human health. Vitamins are a large family, dozens of vitamins are known at present, which can be roughly classified into fat-soluble and water-soluble categories depending on their hydrophobicity.
The detection of plant vitamins generally includes two steps: extraction and purification of vitamin, and identification of vitamin.
STEMart is able to efficiently and accurately detect the change of vitamins in plant samples with high-performance liquid chromatography, liquid chromatography-mass spectrometry, and biochemical methods.
Methods for Vitamin Extraction and Purification
- Ultrasonic assisted extraction (UAE)
- Supercritical fluid extraction (SFE)
- Solid phase extraction (SPE)
- Liquid–liquid extraction (LLE)
- Dispersive liquid–liquid micro-extraction (DLLME)
Methods for Vitamin Identification
- Chromatography methods
- Electrophoretic methods
- Microbiological assays
- Enzyme-linked immunosorbent assay (ELISA)
- Biosensors
- Fluorescence spectrometry
