The identification was performed according to the elution order on C30 column, UV–vis spectrum characteristics and the injection of all-trans-β-carotene standard (0.125–15 μg.mL−1). 2.6. Quantification of the lipid content of the extracts The lipid content of the extracts was determined ...
The diffuse reflectance absorption spectra for the powder samples were measured using a double beam Neosys-2000 UV–Vis spectrophotometer (Scinco). X-ray photoelectron spectroscopy (XPS) was performed using a Thermo-VG Scientific MultiLab 2000 with a monochromatic Al Kα X-ray source (1486.6...
The UV wavelength for the HPLC was optimized according to the UV spectrum and maximum absorption for each standard component; the wavelength was set at 320 nm for detecting the first two components and 365 nm for detecting the third. Five different concentrations of the standard solutions ...
Antioxidant activity testing with the CUPRAC method was carried out using a UV-Vis spectrophotometer. The maximum wavelength of CUPRAC was 453 nm with absorbance of 0.497 nm [31,32]. Determination of antioxidant activity in the ethanolic extract of the stem of E. rubroloba A.D. Poulsen compare...
