Figure 3From: Chemical constituents and free radical scavenging activity of corn pollen collected from Apis mellifera hives compared to floral corn pollen at Nan, Thailand Representative TLC plates showing the compound profile. (A), Lanes 1–8 contain fractions 31, 33, 35, 37, 39, 41, 43 and 45, respectively, from the Sephadex LH-20 chromatography of CDEb5-5. The potentially pure band of fractions# 33–45 (pooled as compound I) is indicated by an arrow. (B), Lane 1 contains CDEb5 while lane 2 contains pooled fractions# 70–109 from CDEb5–6 (compound II, indicated by an arrow). The solvent system used in the shown TLC plates were (A) 1:19 (v/v) methanol: DCM and (B) 1:9 (v/v) methanol: DCM. TLC plates shown are representative of three replicates.Back to article page
