Composition and Antioxidant Activity of Geopropolis Collected by Melipona subnitida (Jandaíra) Bees
An investigation of the geopropolis collected by Melipona subnitida (jandaíra) stingless bee led to the isolation and characterization of two phenylpropanoids, 6-O-p-coumaroyl-D-galactopyranose (1) and 6-O-cinnamoyl-1-O-p-coumaroyl-β-D-glucopyranose (2), and seven flavonoids, 7-O-methyl-naringenin (...

description | An investigation of the geopropolis collected by Melipona subnitida (jandaíra) stingless bee led to the isolation and characterization of two phenylpropanoids, 6-O-p-coumaroyl-D-galactopyranose (1) and 6-O-cinnamoyl-1-O-p-coumaroyl-β-D-glucopyranose (2), and seven flavonoids, 7-O-methyl-naringenin (3), 7-O-methyl aromadendrin (4), 7,4′-di-O-methyl aromadendrin (5), 4′-O-methyl kaempferol (6), 3-O-methyl quercetin (7), 5-O-methyl aromadendrin (8), and 5-O-methyl kaempferol (9). The structure of the new phenylpropanoid (1) was established from IR, LC-ESI-MS, and NMR spectral data, including 2D NMR experiments. The extract and fractions demonstrated significant antioxidant activity in DPPH, ABTS, and β-carotene/linoleic acid tests. |
