Objective: To provide a quick and simple method to identify different Chinese medicine material of Fritillaria.
Method: The thermograms and differential thermograms of nine Fritillaria powders were obtained by thermal analyzer.
Result: By analyzing the thermograms of nine Fritillaria powders, we concluded that the thermal stability of nine Fritillaria powders was much different each other due to the different geography origin. The thermal stability of F. hupehensis was highest among nine Fritillaria, while F. ussurensis was the lowest. The different Fritillaria showed their own DTA spectra respectively.
Conclusion: According to the differences in the thermal properties of nine Fritillaria powders, the origins of Fritillaria could be easily identfied.

To investigate the effects of different initial processing methods on the quality of Fritillaria taipaiensis, this study explored the effects of anti-browning treatment, drying methods, and drying temperatures on the commercial characters, chromaticity values, and alkaloid and nucleoside components of Fritillariae Taipaiensis Bulbus. The results were comprehensively evaluated through correlation analysis(CA), principal component analysis(PCA), and hierarchical clustering analysis(HCA). Compared with those of the direct drying group(WD60), the chromaticity values(ΔE*) of the groups with scraped outer skin( FHB1) and mixed lime powder treatments(FHB2) were significantly reduced, indicating the inhibition of the browning process.

Fritillaria is a well-known health-promoting food, but it has many varieties and its market circulation is chaotic. In order to explore the differences in volatile organic compounds (VOCs) among different varieties of Fritillaria and quickly and accurately determine the variety of Fritillaria, this study selected six varieties of Fritillaria and identified and analyzed their volatile components using gas chromatography-ion mobility spectrometry (GC-IMS), establishing the characteristic fingerprints of VOCs in Fritillaria. In all samples, a total of 76 peaks were detected and 67 VOCs were identified.

Fritillaria has a long history in China, and it can be consumed as medicine and food. Owing to the high cost of Fritillaria cirrhosa, traders sometimes mix it with the cheaper Fritillaria thunbergii powder to make profit. Herein, we proposed a laser-induced breakdown spectroscopy (LIBS) technique to test the adulteration present in the sample of Fritillaria cirrhosa powder.

Background: In this study, Chinese herbal compound prescriptions combined with Chinese medicine powder were evaluated for the treatment of chronic atrophic gastritis with erosion.
Methods: This multi-center, randomized, positive drug control clinical trial randomly assigned 216 patients with chronic atrophic gastritis with erosion to three groups: (1) control group: aluminum plus magnesium suspension thrice per day for 4 weeks; (2) test group 1: Chinese herbal compound prescriptions twice a day plus Sanqi (Panax notoginseng) powder twice a day for 4 weeks; (3) test group 2: Chinese herbal compound prescriptions twice a day plus Sanqi (Panax notoginseng) powder and Zhebeimu (Fritillaria thunbergii Miq.) powder twice a day for 4 weeks.
