“…LDA was applied for qualitative discrimination and PLS modelling for quantitative analysis, thus showing the high potential of this technique (Cetó et al, 2020). A reverse phase high performance liquid chromatography (RP-HPLC) was applied by Sahu et al (2020) to determine adulteration in turmeric with artificial color metanil yellow (MET). The method was found to be robust with an R 2 of 0.99 and a coefficient of variation of 1.68%.…”

Stable Isotope Ratio Analysis for the Authentication of Natural Antioxidant Curcuminoids from Curcuma longa (Turmeric)

“…The three curcuminoid components (curcumin, demethoxycurcumin and didemethoxycurcumin) were measured following the method reported by Sahu et al [27]. In brief, an HPLC system (Shimadzu, Kyoto, Japan), consisting of two pumps LC 20AD, a photodiode array detector SPD-M20A, with an automatic sample injector, all from Shimadzu, was used.…”

Experimentally designed chemometric models for the assay of toxic adulterants in turmeric powder

“…A literature survey revealed several methods to detect and/or quantify the adulteration of turmeric, such as HPLC, 50,51 HPTLC, 52,53 voltammetry, 54 multispectral imaging, 55 spectrophotometry 56 and FTIR. 57–60 However, the reported literature failed to reveal a single analytical method for the simultaneous assay of MY, AO and LCM in turmeric powder.…”
