| Summary: | 碩士 === 國立中興大學 === 生物產業機電工程學系所 === 98 === Near-infrared spectroscopy is an analytical method with nondestructive, rapid and no or minimal sample preparation. It has been applied widely in biomedical detection. Many literatures show that the near-infrared spectroscopy technology could be applied in the rapid detection of herbal medicine.
The purpose of this study is to classify the cultivation area and quantity of ginseng by near infrared spectroscopy. From the repeatability of the spectra wavelength and different methods of sample preparation, the selected band is largely ranged from the 960nm to 1600nm. The solid sample of American ginseng can be observed from the band characteristics.
The results indicated that the NIR method could be applied to classify of cultivation area of ginseng. In quantitative analysis, the ginseng could be analysised with a single geographical origin of the sample and when using its solution as a sample. However, the mixed sample could not be classified.
