[Identification of Panax notoginseng base on solid three-dimensional fluorescence fingerprint spectra technology].
OBJECTIVE
To establish the solid three-dimensional fluorescence fingerprint spectra for the main root and branch root of Panax notoginseng.


METHODS
With the Xuesaitong power as a control, the solid three-dimensional fluorescence technique was employed to establish the fingerprint spectra.


RESULTS
The fluorescence peaks of Xuesaitong power were at 230 nm/330 nm,280 nm/660 nm,300 nm/340 nm, 370 nm/590 nm, 440 nm/550 nm, and 490 nm/610 nm. Among of them, the 300 nm/340 nm peak was the strongest. The fluorescence peaks of Panax notoginseng main root power were at 230 nm/340 nm,290 nm/340 nm,370 nm/480 nm,and 430 nm/540 nm. Among of them, the peak at 290 nm/340 nm was the strongest. The branch root of Panax notoginseng was at 280 nm/450 nm,290 nm/350 nm and 350 nm/440 nm,and the peak at 350 nm/440 nm was the strongest. All of them had the peak at 290-300 nm/340-350 nm, this peak was the strongest in Xuesaitong and Panax notoginseng main root power, but 350 nm/440 nm was the strongest in the branch root of Panax notoginseng. Only the peak at 230 nm/330-340 nm was not detected in the branch root of Panax notoginseng.


CONCLUSIONS
The solid three-dimensional fluorescence fingerprints spectra are established. Using peaks at 290-300 nm/340-350 nm and 230 nm/330-340 nm as characteristics of the fluorescence peak can efficiently identify main root and branch root of Panax notoginseng.
