NEW POTENTIAL ALLELOCHEMICALS FROM AERIAL PARTS OF INDIGOFERA TRIFOLIATA LINN.
AbstractTwo new potential allelochemicals were isolated from ethanolic extract of the aerial parts of Indigofera trifoliata Linn. Along with three known compounds Tricin (3), Taraxerol (4) and 5-hydroxy-3, 4′, 7-trimethoxyflavone (5). The structures of new allelochemicals were characterized as 6, 3′, 4′-trihydroxy-5, 7, 8-trimethoxyflavanone-4′-O-α-L-rhamnopyranosyl-(1→4)-O-β-D-xylopyranosyl-(1→3)-O-β-D-galacto pyranoside (1) and 3, 5, 7-trihydroxy-3′,4′-dimethoxyflavone-3-O-β-D-galactopyranosyl-(1→4)-O-β-D-arabinopyranosyl-7-O-α-L-rhamno pyranoside (2) by various color reactions, spectral analysis and chemical degradations. Allelo chemicals can be defined as secondary plant metabolites, produced by plants, algae, bacteria, fungi and viruses that influence the growth and development of agricultural and biological systems (excluding animals).
