During the past decade, Raman spectroscopy has been increasingly applied for the analysis
of objects of art and antiquities. Since the publication of the database of Raman spectra of …

Brazilein extract from sappan wood (Caesalpinia sappan L.) has potential for use as natural
food colorant since it has no unique flavor and taste. Although brazilein has long been …

Introduction Brazilin is a promising natural red dye, extracted from the wood of Caesalpinia
sappan L. It exhibits several pharmacological activities including anti-inflammatory …

Surface‐enhanced Raman spectroscopy (SERS) was used in this work to obtain highly
detailed spectra of artists' red lake pigments and colorants. In the past, Raman spectroscopy …

This article deals with the potential of Fourier transform (FT) Raman spectroscopy in
discrimination of botanical species of green and roasted coffees. There are two species of …

In the present study, several natural organic dyes used in antiquity, especially in textile
dyeing, were analysed by surface‐enhanced Raman scattering (SERS) spectroscopy, in …

Brazilin is a nearly colorless dye precursor obtained from the heartwood of several species
of trees including brazilwood from Brazil, sappanwood from Asia and the Pacific islands, and …

Surface-enhanced Raman spectroscopy (SERS) is an ideal tool for analyzing dyes on
historical textiles because it requires very little sample compared to other available …

The uses of natural dyes are getting popularized due to the increased awareness regarding
the toxicity of many chemical colorants. The chemical colorants are being replaced by the …
