[Analysis and Identification of H. rhamnoides subsp. sinensis Harvested From Different Producing Areas by FTIR Spectroscopy].

The accurate identification of traditional Chinese medicine (TCM) which collected from different producing areas is important for its quality control and clinical effects. In the present study, Fourier transform infrared spectroscopy (FTIR) combined with second derivative spectra were used to identify and analyze H. rhamnoides subsp.

[Study on HPLC fingerprint and quantitative analysis of 3 components of Tibetan medicine Gyantse Seabuckthorn].

This study is to establish an HPLC fingerprint and quantitative analysis of 3 components of Gyantse Seabuckthorn from different producing areas.The separation was developed on Shimadzu InertSustain C18column (4.6 mm × 250 mm,5 μm) by gradient elution with acetonitrile and 0.

[HPLC fingerprint of Tibetan medicine Shaji Gao].

This study established an HPLC fingerprint of Tibetan medicine Shaji Gao from different habitats and lay a foundation for Shaji Gao varieties identification and preparation process. The chromatographic condition was as follow: Agilent zorbax SB-C18 (4.6 mm x 250 mm, 5 μm) eluted with the mobile phases of acetonitrile and 0.

[Study on three different species tibetan medicine sea buckthorn by 1H-NMR-based metabonomics].

The 1H-NMR fingerprints of three different species tibetan medicine sea buckthorn were established by 1H-HMR metabolomics to find out different motablism which could provide a new method for the quality evaluation of sea buckthorn. The obtained free induction decay (FID) signal will be imported into MestReNova software and into divide segments. The data will be normalized and processed by principal component analysis and.
