Chemical constituents of Curcuma kwangsiensis and their antimigratory activities in RKO cells.[Pubmed: 29914271]
Two new sesquiterpenoids, curkwangsien A-B (1-2), and seven known compounds (3-9) were isolated from rhizomes of Curcuma kwangsiensis. Their structures were elucidated by spectroscopic analysis, and the absolute configurations of compounds 1-2 were determined by the quantum chemical ECD calculations. Compounds 3-9 are firstly reported from this plant. In the in vitro assays, compound 3 was found to inhibit human colon cancer RKO cell migration in time-dependent manner.
On-line comprehensive two-dimensional liquid chromatography tandem mass spectrometry for the analysis of Curcuma kwangsiensis.[Pubmed: 29784421]
A novel online comprehensive two-dimensional liquid chromatography (2DLC) coupled with quadrupole time-of-flight (Q-TOF) mass spectrometry (MS) method is developed for the analysis of Curcuma kwangsiensis (C. kwangsiensis) extract. In this system, a newly developed phenyl/tetrazole sulfoether (PTAS) bonded stationary phase was introduced to construct RPLC×RPLC combined with C18. The unique structure endowed PTAS with very different selectivity from C18, reaching a high orthogonality of 93.2%. Moreover, such a combination settled compatibility issues because of the weaker hydrophobic retaining property of PTAS, thus allowing direct interfacing in online configuration. As a result of coupling with the mass spectrometry, a four-dimensional (4D) data plot was presented, in which 439 peaks (containing positive mode and negative mode) were counted, and 105 compounds were grouped and tentatively identified in C. kwangsiensis extract, including 73 unreported ones. Some novel types of compounds with masses exceeding 500 were discovered for the first time. Besides, compared to one-dimensional liquid chromatography (1DLC), the great resolution power of this system allowed separation of more isomers. These results provide supplementary to the material basis of C. Kwangsiensis and in-depth research should be conducted. The configuration of RPLC×RPLC-Q-TOF MS can be a powerful and efficient tool for separation and characterization of chemical substances in complicated herbal extracts.

Diarylheptanoid from rhizomes of Curcuma kwangsiensis (DCK) inhibited imiquimod-induced dendritic cells activation and Th1/Th17 differentiation.[Pubmed: 29454234]
Dendritic cells (DCs) are critical for initiating the activation and differentiation of T cells in inflammatory diseases including psoriasis. Curcuma kwangsiensis S.G. Lee & C.F. Liang is a herb for treating psoriasis and we previously found Diarylheptanoid from rhizomes of Curcuma kwangsiensis (DCK) inhibited keratinocytes proliferation. However, it is unknown whether DCK influences DC functions. Thus we aimed to explore whether DCK affect the major immunological functions of DCs.

Curcumol induces cell cycle arrest in colon cancer cells via reactive oxygen species and Akt/ GSK3β/cyclin D1 pathway.[Pubmed: 28684297]
Curcuma kwangsiensis S. G. Lee & C. F. Liang (Guangxi ezhu, in Chinese) belongs to the Zingiberaceae family, has been used as a traditionally Chinese medicine nearly 2000 year. Curcumol is one of the guaiane-type sesquiterpenoid hemiketal isolated from medicine plant Curcuma kwangsiensis S. G. Lee & C. F. Liang, which has been reported possesses anti-cancer effects. Our previous study found that the most contribution to inhibit nasopharyngeal carcinoma cell growth was curcumol.

Development of intron length polymorphism markers in genes encoding diketide-CoA synthase and curcumin synthase for discriminating Curcuma species.[Pubmed: 26471689]
Various Curcuma rhizomes have been used as medicines or spices in Asia since ancient times. It is very difficult to distinguish them morphologically, especially when they are boiled and dried, which causes misidentification leading to a loss of efficacy. We developed a method for discriminating Curcuma species by intron length polymorphism markers in genes encoding diketide-CoA synthase and curcumin synthase. This method could apply to identification of not only fresh plants but also samples of crude drugs or edible spices. By applying this method to Curcuma specimens and samples, and constructing a dendrogram based on these markers, seven Curcuma species were clearly distinguishable. Moreover, Curcuma longa specimens were geographically distinguishable. On the other hand, Curcuma kwangsiensis (gl type) specimens also showed intraspecies polymorphism, which may have occurred as a result of hybridization with other Curcuma species. The molecular method we developed is a potential tool for global classification of the genus Curcuma.
Structural characterization and immunostimulating activity of a levan-type fructan from Curcuma kwangsiensis.[Pubmed: 25783019]
A fructan designated as CKNP with apparent molecular weight of 5.3kD was isolated from the hot water extract of Curcuma kwangsiensis through a combination of ion-exchange chromatography on DEAE 650M and gel filtration on Superdex G-200. CKNP was characterized by chemical derivatization as well as HPLC, GC, and GC-MS technologies. Structural studies revealed that CKNP is composed predominately of fructose (96.8%) and a small amount of glucose (3.2%) with a degree of polymerization (DP) of 30-31. It was deduced to be a levan-type fructan containing a backbone composed of (2→6)-linked β-d-Fruf residues and single β-d-Fruf residues as side chains branched at the O-1 position along the backbone. Preliminary in vitro bioactive tests on RAW 264.7 murine macrophage cells revealed that the levan-type fructan from C. kwangsiensis shows significant immunostimulating activity based on its ability to stimulate macrophage proliferation and enhance phagocytosis.
