Abstract
The extraction and physicochemical properties of pigment from rhododendron dauricum L were investigated. The optimal extraction conditions on pigment by orthogonal assay were as followed] citric acid content 2%t radio of mate rial /solvent 1 : 10, extracting time 1 h, extracting temperature 50 ℃. The maximum absorption wavelength of pigment was 530 nm, This pigment is resistant to heat, light and common ingredients. Most metal ions have no undesirable effect on it, but Fe3+ , Cu2+ could change its color. The pigment is resistant to oxidizing agent, however, it was unstable to reducing agent.关键词
