Method for nondestructively identifying authenticity of agilawood

Abstract

The invention discloses a method for nondestructively identifying authenticity of agilawood.The method includes the steps that a fluorescence spectrum imaging technology is adopted to obtain a spectral cube of original-state authentic agilawood, data analysis is conducted on the spectral cube, spectral characteristics are obtained, and an agilawood standard database is established; full-wave bandscanning ranging from 450 nm to 950 nm in range is conducted on an agilawood sample to be detected, the spectral cube of the sample to be detected is collected, and the data collection is implementedafter the spectrum of the interested region is obtained, the characteristic spectrum of the sample to be detected is extracted, and the characteristic spectrum is matched with the spectrum chart of the authentic agilawood in the agilawood standard database, and judgment of authenticity of agilawood sample to be detected is achieved according to similarity of a spectral curve. The method for identifying authenticity of agilawood in the lossless modeis proposed for the first time, by means of the method, identification of authenticity of agilawood of any shape and size can be achieved, the process is lossless, rapid and high in accuracy; the method can be used for an agilawood collection market, a traditional Chinese medicine market and the like, and an accurate, convenient and fast detection means is provided for agilawood quality control.

Description

technical field [0001] The invention relates to a method for identifying the authenticity of the famous and precious medicinal plant agarwood, belonging to the technical field of traditional Chinese medicine identification, wood quality detection or precision forestry. Background technique [0002] Agarwood ( Aquilaria sinensis Lour.Gilg) is a dark heartwood resin formed in the Agarwood tree, which is widely distributed in Hainan, Guangxi and Guangdong provinces in southern China. Agarwood is formed when the agarwood tree becomes infected with mold. Before the infection, the heartwood of the agarwood tree is relatively white and shiny; however, as the infection spreads further, the agarwood tree will produce a black aromatic resin to prevent the invasion of the infection, and finally promote Very high density, deep black resin embedded heartwood formation. [0003] Known for its unique scent, agarwood is often used in perfumery. At the same time, it is also a kind of pre...
