Fig. 2From: Development and application of a chemical profiling method for the assessment of the quality and consistency of the Pelargonium sidoides extractComparison of UV spectra (210–330 nm). All 7 common peaks (a–c) were detected only 254 and 280 nm in our profile method. The figure showed that the wavelength of 254 nm does not have a large difference in all peak areasBack to article page
