A chalcone (Pongamol) and phytoconstituents of .

stem extract fractions shows more amount of Cyclohexane, 1-ethenyl-1-methyl-2,4-bis(1-methylethenyl)-, (1α,2β,4β)- (62.32%). Secondary metabolites contents were higher in stem than root of It is the first time a chalcone (Pongamol) was crystallised from the column chromatography fraction of stem extract identified by using FT-IR and XRD.

Green preparation of seaweed-based silver nano-liquid for cotton pathogenic fungi management.

Silver nanoparticles (Ag NPs) were synthesised using the crude ethyl acetate extracts of and evaluated their bioefficacy against two crop-damaging pathogens. The sets of lattice planes in the XRD spectrum for the Ag NPs were indexed to the 111, 200, 220 and 311 orientations and support the crystalline nature of the Ag NPs. The 3414 and 2968 cm peaks were observed in crude algal thallus extract and they were characteristic of terpenoids.
