The limits of detection and quantification for all compounds were within a range of 0.2–1.1 mg/ml. Quantitative determination of the four biomarkers showed high levels of aloeresin A (129.0–371.6 mg/ mg) and aloesin (111.8–561.8 mg/mg) while aloin A (21.3–133.4 mg/mg) and aloin B (18.4–149.7 mg/ mg) were present in lower amounts. Hierarchical cluster analysis revealed two major groups within the dataset. However geographical locality was not a major factor in the clustering observed. This validated, ultra-fast method for simultaneous quantification of chromones and anthrones present in A. ferox is recommended for routine quality control analysis.]]> Fri 07 Aug 2020 08:20:01 SAST ]]> The application of vibrational spectroscopy techniques in the qualitative assessment of material traded as ginseng. http://tutvital.tut.ac.za:8080/vital/access/manager/Repository/tut:5238 Fri 04 Sep 2020 12:55:25 SAST ]]>
