Table 5 The weight and character of the pooled active fractions derived from the Sephadex LH-20 size exclusion chromatography of the bee pollen derived CDEb-5 fraction

From: Chemical constituents and free radical scavenging activity of corn pollen collected from Apis mellifera hives compared to floral corn pollen at Nan, Thailand

  1. a,bYield as a % of the aCDEb5 fraction and bof the bee pollen
  2. cQualitative free radical scavenging activity, as determined by the DPPH assay sprayed onto the TLC plates, where -, +, ++ and +++ represent no, weak, moderate and strong color change (activity).
