Two phenolic compounds, methylkarranjic (1) acid and pongamol (2), were isolated from the petroleum ether soluble fraction of an ethanolic extract of Derris indica seeds. The structures of these compounds were confirmed by LC-MS and a series of 1D and 2D NMR data. The solvent solvent partionates of the ethanolic extract and compounds (1 and 2) exhibited moderate antibacterial activity against several test organisms. The minimum inhibitory concentrations (MICs) of 1 and 2 were found to be in the range of 32-128 μg/ml against Bacillus megatorium, Streptococcus β-haemolyticus, Shigella dysenteriae and E. coli.

The residual effect of eight herbicides (Pendimethalin, Pretilachlor, TriasulfuronEthoxysulfuron, Pyrazosulfuron Ethyl, Carfentrazone – ethyl, Carfentrazone – ethyl+ Isoproteuron, 2, 4 –D) used in wheat of Agronomy Field Laboratory during March to June 2014 was evaluated for the sunflower. The eighteen herbicide treatment combinations of the eight herbicides used in wheat. The experiment was conducted in Random Complete Block Design (RCBD) with three replications. The effect of herbicide residues on the sunflower was evaluated in terms of germination, the seedling root and shoot length, leaf chlorophyll content and seeding dry matter. The result showed that the seedling establishment of sunflower was not adversely affected by the herbicides applied to the previous wheat crop.
