Abstract
Introduction: Wenyujin Rhizoma Concisum, named as Pian Jianghuang (PJH) in China, is the decoction piece from the dried rhizome of Curcuma wenyujin Y. H. Chenet C. Ling, has been used to relieve pain for many years in China. However, the qualities of PJH in different districts differ greatly due to their growing environments, which would affect their clinical applications.
Objective: To evaluate the qualities of PJH from different districts in China.
Methods: HPLC, Heracles NEO ultrafast gas-phase electronic nose, and Fourier transform near-infrared (FT-NIR) spectroscopy were applied to estimate the qualities of PJH from different districts in China.
Results: By HPLC, the average contents of neocurdione, curdione, germacrone, and furanodiene were 0.203%, 0.151%, 0.022%, and 0.022% in Fujian (FJ); 0.447%, 0.786%, 0.298%, and 0.276% in Zhejiang (ZJ); 0.082%, 0.259%, 0.038%, and 0.019% in Yunnan (YN); 0.041%, 0.022%, 0.260%, and 0.024% in Guangxi (GX); and 0.026%, 0.091%, 0.260%, and 0.016% in Anhui (AH), respectively. By Heracles NEO ultrafast gas-phase electronic nose, the unique odor components in PJH from FJ, YN, and GX were 1,2,4-thiadiazole,5-ethoxy-3-(trichloromethyl), 5,6,7,8-tetrahydroquinoxaline, and 1,3,5-trimethylbenzene, respectively, while ZJ and AH both contained two unique odor components, respectively: pentyl pentanoate and dill ether (ZJ), myrcene, and 2-pentadecanone (AH). Moreover, PJH from above five districts could be discerned quickly by FT-NIR.
Conclusion: The application of multidimensional analytical techniques in quality assessment of PJH from different districts in China would provide a new idea for quality control and geographical origin traceability of traditional Chinese materia medica.
期刊介绍：
Phytochemical Analysis is devoted to the publication of original articles concerning the development, improvement, validation and/or extension of application of analytical methodology in the plant sciences. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bio-screening), extraction, separation, purification, identification and quantification of compounds in plant biochemistry, plant cellular and molecular biology, plant biotechnology, the food sciences, agriculture and horticulture. The Journal publishes papers describing significant novelty in the analysis of whole plants (including algae), plant cells, tissues and organs, plant-derived extracts and plant products (including those which have been partially or completely refined for use in the food, agrochemical, pharmaceutical and related industries). All forms of physical, chemical, biochemical, spectroscopic, radiometric, electrometric, chromatographic, metabolomic and chemometric investigations of plant products (monomeric species as well as polymeric molecules such as nucleic acids, proteins, lipids and carbohydrates) are included within the remit of the Journal. Papers dealing with novel methods relating to areas such as data handling/ data mining in plant sciences will also be welcomed.
