Antityrosinase activity and photosynthetic pigments in seaweed treated sprouts of Vigna aconitifolia

Abstract

The seaweed, Ascophyullum nodosum is the focus of the research these days and is looked upon as an important alternative bio-fertilizer. For this purpose the interaction of the seaweed with different plants including legumes is important to understand. We previously noticed lesser pigmented nodules in legume plant Vigna aconitifolia, when grown in presence of A. nodosum Extract (ANE). We therefore studied the effect of the ANE on the tyrosinase inhibition activity, an enzyme known to produce melanin pigment. In addition, the effect of the treatment of ANE on the photosynthetic pigments was also recorded. The seeds of Vigna aconitifolia were treated with 0%, 0.01%, 0.05%, 0.10%, 0.50% and 1.0% of A. nodosum extract for different time periods from 0–24 hours. It was observed that with the increased exposure to the seaweed (ANE), the tyrosinase inhibition activity also increased up to 0.05% of the seaweed concentration at 24 h of soaking and decreased after increasing the concentration of ANE from 0.1–1.0% at the same time period. Seed treatment with 0.05% seaweed was found to be the most effective concentration showing highest tyrosinase inhibition.

Synthesis of nanoparticles from weeds a better alternative of weed utilization: A review

“…Synthesis of nanoparticles from weeds has drawn more attention because of inexpensive, nonpathogenic, sustainable and quick single step process. The plant extract have natural tendency to reduce and stabilize silver ions because of presence of a number of biomolecules like terpens, tannins, alkaloids, phenolics, aminoacids, saponins and vitamins [20] . A large number of weeds are reported that reduce reduced silver ions and its importance (Table 1).…”

“…The synthesis of nanoparticles from ecofriendly material like plant parts (root, stem, leaf), algae, fungi, bacteria have many sustainable use and harmonious to biomedical as well as pharmaceutical applications because in this no harmful chemical is used in the protocol of nanoparticle synthesis. In all emergent area of research i: e physical, chemical and biological sciences nanoparticles have great use [20] . In many areas nanoparticle gaining attention such as biomedicines, cosmetics, drug delivery, healthcare, eco environment, food and feed, water disinfectant, antimicrobial filter, wound dressing material, air filtration, sensor etc.…”
