Abstract
ABSTRACT − The Artemisia princeps (Compositae) has been used in traditional Korean medicine for the treatment ofmicrobial infections and inflammatory diseases. Since A. princeps is generally difficult to be discriminated from A. cap-illaris, A. caplillaris has been misused in place of A. princeps. To solve this problem, a rapid and nondestructive methodfor discrimination of A. princeps and A. capillaris samples was developed using near infrared spectroscopy (NIRS) in thepresent study. A principal component analysis (PCA) and a partial least squares discrimination analysis (PLS-DA) were per-formed to discriminate two species. As a result, with the use of PLS-DA, A. princeps and A. capillaris were clusteredaccording to their genus. These outcomes indicated that the NIRS could be useful for the discrimination between Artemisiaprinceps and Artemisia capillaris.Key words − Artemisia princeps, Artemisia capillaris, Near infrared spectroscopy (NIRS), Partial least square dis-crimination method(PLS-DA)
