The sap expelled from the fresh harvest of Kappaphycus alvarezii , a red seaweed growing in tropical waters, has been reported to be potent foliar spray. Tandem mass spectrometry various organic extracts confirmed presence plant growth regulators (PGRs) indole 3-acetic acid, gibberellin GA(3), kinetin, and zeatin. These PGRs were quantified state after 1 year storage by ESI-MS without recourse chromatographic separation. Quantification was validated against HPLC data. results may useful...

In vitro somatic embryogenesis and regeneration of embryos to whole plants through micropropagules was successfully demonstrated from pigmented uniseriate filamentous callus Kappaphycus alvarezii (Doty) Doty in axenic cultures. More than 80% the explants cultured on 1.5% (w/v) agar‐solidified Provasoli enriched seawater (PES) medium showed development. The induction rate consistently higher for laboratory‐adapted plants. excised grew well subcultures maintained its growth prolonged periods...
Abstract Grafting of agar and κ‐carrageenan with polyvinylpyrrolidone (PVP, average molecular weight 10,000 D) in an aqueous medium at a pH about 7 produced agar‐ graft ‐PVP κ‐carrageenan‐ blends capable forming hydrogels. The reaction was carried out microwave irradiation the presence water‐soluble initiator, potassium persulfate. Optimum conditions for obtaining hydrogels grafted products were achieved. structural characteristics thermal stability studied by Fourier transform infrared, 13...
The present work reports a standalone integrated scheme for the production of 5-hydroxymethyl furfural (HMF) and potassium sulphate (K2SO4) from granular biomass rich in sulphated polysaccharide, κ-carrageenan. Fresh Kappaphycus alvarezii seaweed was crushed to expel juice KCl (0.7 m3 t−1 fresh seaweed) (0.04 t dry weight per seaweed). latter yielded κ-carrageenan through seawater extraction. HMF derived this phycocolloid reaction with Mg(HSO4)2 acid catalyst isolated pure form. Galactose...
Epoxyeicosatrienoic acids were isolated and purified from female rabbit kidneys.They identified as a group, prior to resolution, by packed column gas-liquid chromatography-mass spectroscopic techniques their methyl esters well trimethylsilyl bromohydrin esters.Initial capillary spectral analysis of the corresponding hydrogenated pentafluorobenzyl revealed presence 8,9and 14,15-epoxyeicosatrienoate regioisomers.These results, in conjunction with documented vitro biological activities...

Abstract κ‐Carrageenan‐ graft ‐PAAm, a copolymer hydrogel of κ‐carrageenan (kC) and acrylamide (AAm), has been synthesized in aqueous medium at ∼ pH 7 the presence initiator potassium persulfate (KPS), using microwave irradiation. The reaction conditions were optimized by varying concentration AAm KPS to obtain hydrogels having different nitrogen contents e.g., %N 6.35, 10.56, 11.05. It was observed that 11.05 gives superior adhesive properties whereas with 10.56 produces absorbent...
