Fig. 1From: Development and application of a chemical profiling method for the assessment of the quality and consistency of the Pelargonium sidoides extractUV spectra of 7 common peaks (a–g) for specificity. Peaks (a), (b), and (c) were detected specific wavelengths at 256.6, 253.1, and 255.5 nm. Peaks (d), (e), and (g) were detected specific wavelengths at 323.3, 322.1, and 326.8 nm, and f at 297.0 nmBack to article page
