HPLC semi-preparativo serie LC-4000 JASCO_PREPNAT

Language English

The required instrument is a High-Performance Liquid Chromatography system developed to operate in both analytical and preparative modes, in ultra-fast, fast, and conventional chromatography, and using columns with a particle size of 1.8 microns. The chromatographic system consists of several units and accessories that compose a versatile and high-performance instrument for the qualitative and quantitative analysis of complex mixtures and for the purification of large amounts of samples.

Peptidomic approach for the identification of peptides with potential antioxidant and anti-hyperthensive effects derived from Asparagus by-products

Asparagus waste represents products of great interest since many compounds with high biological value are located in the lower portion of the spears. The extraction of bioactive compounds from asparagus by-products is therefore crucial for the purpose of adding value to these by-products. In this paper, bioactive peptides from asparagus waste were extracted, digested, purified and identified. In particular, Alcalase® was chosen as the enzyme to use to obtain protein hydrolysate due to its low cost and, consequently, the possibility of implementing the method on a large scale.
