Comparative Studies on the Discrimination of Angelicae Gigantis Radix by Near-infrared Spectroscopy; Electronic Nose and X-ray Fluorescence Spectrometry

Angelicae gigantis radix is the root of the perennial plant, which belongs to the family Umbelliferae. However this herbal drug is represented quite different chemical components according to its different genus name, though other herbal drugs (I.e. Leonuri Herba, Xanthii Fructus and so on) show similar constituents on the same name. The root of Angelica gigas containing the coumarin compounds is commonly used in Korea, while Angelica sinewis and Angelica arutiloba including phthalide compounds are used in China and Japan, respectively as Angelicae gigantis radix. In this paper, a nearinfacted spectroscopic method was developed to determine genus name of Angelica spp., especially A.gigas and A. sinensis which are commonly misused in herbal markets. X-ray fluorescence spectrometry and electronic nose have been also applied as nondestructive methods to discriminate A. gigas from A sinenis according to their specific properties.
