      J. Chromatogr. Sci. 54 (8), 1421-1427 (2016). Development of a simple, cost-effective and reliable method for quantification of naphthoquinones, found as natural red color pigments in roots of Arnebia benthamii (Wall. ex G.Don) I.M. Johnst., by HPTLC on silica gel with hexane – ethyl acetate – methanol 16:3:1. Determination of shikonin (hRf 37) and β,β-dimethylacryl shikonin (hRf 58) in the methanol extract by densitometry at 520 nm. The linearity was 0.1-8 µg/zone. The average recovery was >97 % for both and the intraday and interday precision for the quantification of naphthoquinones was good (%RSD <2.0 %). The LOD were 13 and 15 ng/zone for shikonin and β,β-dimethylacryl shikon and the LOQ were 39 and 44 ng/zone, respectively.
