Abstract
In this study, phytochemicals from the wold and cultivated Lithospermum erythrorhizon (gromwell), which has been used for medicinal purpose or natural coloring material from the old days, were extracted by methanol and fractionated with hexane. The shikonin compounds in the fraction was isolated and their chemical structures were identified by $^1H$ and $^{13}C-NMR$. It was found that compound I was the shikonin substance with molecular weight of 288.3 and chemical formula of $C_{16}H_{16}O_5$, and compound II being deoxyshikonin substance with molecular weight of 272.3 and chemical formula of $C_{16}H_{16}O_4$. The Quantities of these compounds in the wild and cultivated gromwells was determined.
