SPECTROPHOTOMETRIC FINGERPRINT IN VIZ FOR SEVEN HYDROALCOHOLIC VEGETABLE EXTRACTS
Keywords:
Flavonoids, fingerprinting method, spectroscopic methods, vegetable extract
Abstract
In this work, we aimed to determine the spectral fingerprint in VIZ for seven extracts made from hypoglycemic species. Absorbance measurement was performed using a UV-VIS Jasco V-530 Spectrophotometer coupled with a computer, the subsequent processing of the absorption spectra in the VIZ being performed with the Jasco V- 500W (V-500 / FP-750) software. Spectral analysis in the VIZ of tinctures reveals the presence of the maximum absorption for chlorophyll a (640-670 nm) and two absorption peaks at λ 530-540 nm and 600-610 nm, attributed to the presence of flavonoids.
