ARTE @ Spectral Service – Aloe Vera, a medicinal plant?
Aloe vera has become a worldwide must-have product due to its reputed healing power. The plant is advertised to deliver moisture to skin as a cream, to cool the burn and to heal even cancer. Is Aloe vera really a miracle cure? Xenius (ARTE) got to the bottom of the well-known plant and visited us to look behind the scenes of the analytical chemistry.
We analyze routinely fresh and processed Aloe vera – leaves, juice, powder – from all over the world. In the Xenius documentary (click here) we presented how the Aloe vera sample is prepared for the NMR analysis, how the NMR experiment is set and what information can be extracted from the NMR spectrum.
By using NMR spectroscopy several substances can be analyzed simultaneously within only one measurement: the main components aloverose (polysaccharide), glucose and malic acid; degradation products such as lactic acid, acetic acid, succinic acid, fumaric acid and formic acid; and lastly additives. The Aloe Vera analysis by the powerful NMR technique is presented in our last “Aloe vera” blogpost.
“Was the only the gel or the whole leave used for the product?”, “Is it pure Aloe Vera?”, “Is the Aloe Vera fresh or degraded?” – these are questions which can be easily answered by NMR spectroscopy. Within only one analysis run!
The Xenius documentary was aired on Wednesday, November 11, 2018 (16:55-17:20) on Arte. However, you have the chance to watch the Aloe vera documentary in the ARTE media library (click here).
