产品描述

General description

all-trans-Astaxanthin is a ketocarotenoid, most commonly identified in marine and aquatic animals, including krill, wild salmon, rainbow trout, microalgae, shells of lobster, shrimp,[1][4] seafood products, etc.[4] It is biologically known as a vitamin A precursor, and exhibits strong antioxidant property, much higher compared to vitamin E and β-carotene. Its role in food and the medicinal industry is also well-defined.[3]

Application

all-trans-Astaxanthin may be used as an analytical reference standard for the quantification of the analyte in:
• Microalgae (Green algae), Haematococcus pluvialis using high-performance liquid chromatography (HPLC) with mass spectrometric[1] and fluorescence detection (HPLC-FLD).[2]
• Parapenaeopsis hardwickii using high-performance liquid chromatography (HPLC) with photodiode array detection (PDA).[4]
