The fingerprints of 18 commercially available Ginkgo biloba supplements, 12 samples of raw G. biloba leaves, and three G. biloba standard reference materials from the National Institute of Standards and Technology were acquired directly (no chromatography) by UV spectrometry and after separation using HPLC with a diode array detector. The fingerprints consisted of the UV spectral images, the chromatographic images, and the areas of the 21 most prominent chromatographic peaks. Data were analyzed… CONTINUE READING
